Introduction to Delcam Crispin SoleDesign Delcam Crispin SoleDesign contains functionality for grading shoes in a variety of ways, together with a set of commands to help model shoe soles.

SoleDesign is an add-in program, that runs with PowerSHAPE. We expect you to know how to use PowerSHAPE before using SoleDesign.

Grading You can grade shoes by scaling the whole shoe up or down using a range of methods:


Delcam Crispin SoleDesign • 3

By user-specified scale factors (in X, Y and Z). By user-specified length increments. According to company-standard grading schemes. This is Group grading (see page 33). You can also grade shoes (or boots) in such a way that different 'zones' are scaled by different amounts (or fixed as unscaled) with smooth blending between. This is Zone grading (see page 34). You can use EVA grading (see page 38) to take into account the expansion properties of EVA foam when creating the mold cavity. A series of heels can be graded from a single one (Heel grading (see page 61))

Shoe sole modelling With PowerSHAPE and SoleDesign you can: Wrap a 2D curve onto a surface. This is useful for wrapping an imported 2D curve onto a surface. Create a flat curve from a 3D composite curve that lies on a base surface. Place a 2D composite curve along a profile. Create a variable offset of a wireframe or surface curve. Add sections between profiles. Create a bulge surface. Create a sole using wireframe. Create a new heel using wireframe. Create a workplane relative to the bounding box of the current selection. For further details, see Create workplane above selection (see page 16) and Create workplane under selection (see page 16).

Levels toolbar for SoleDesign The levels toolbar displays the groups of levels that are automatically associated with SoleDesign.

4 • Delcam Crispin SoleDesign


Each of the buttons is associated with turning a group of levels on and off. Currently, only the Sole group levels are active. Levels for last and style lines, upper pieces and accessories are provided as empty level groups. These are ready to place items imported from other modules. - Design - Pieces - Accessories - Sole The footwear tooltips on the groups on the Levels toolbar display graphics rather than text.

The graphical tooltips are for the different groups are as follows: Design Pieces Accessories Sole For further details, see View - Toolbars - Levels

Sole Engineering modelling tools Use the modelling features of PowerSHAPE to do the following: Use Curve Wrapping to wrap a composite curve onto a surface (see page 9). Use Curve Unwrapping to flatten a composite curve (see page 11). Use Create pattern of Objects to create repeating objects on a sole (see page 11). Create a Variable offset of a wireframe or surface curve (see page 12) Use Place Wireframe to place a section between two profiles (see page 13). Create a Bead surface (see page 14). Create a workplane relative to the bounding box. (see page 15)

Wrapping profiles onto surfaces You can wrap a composite curve onto a surface.



At the same time, you can map other curves onto surface representing features on the shoe sole.

The lengths of the composite curve and the wrapped curve will be the same. You can also define the surface using a 2D composite curve.

SoleDesign extrudes the composite curve into a surface and wraps the other composite curve onto the extruded surface.

See Also: Wrapping a shoe profile (see page 11)



Wrapping a shoe profile 1. Create a shoe sole outline and a curve representing a cross section of the shoe sole. 2. Click Curve Wrapping

(Curve toolbar).

3. Use the Wrap Wizard to create the shoe sole wrap. For further details, see Creating a shoe sole wrap.

Flattening a 3D curve onto a surface Flatten is used to flatten a 3D composite curve (see page 11) that lies on a base surface to create the corresponding 2D composite curve. Flattening a shoe profile 1. Select the 3D curve. 2. Click Curve Unwrapping

(Curve toolbar).

3. Use the Unwrap Wizard to create a 2D composite curve. For further details, see Using the Unwrap Wizard.

Placing profiles on a drive curve You can add repeating features on a sole using composite curves.



1. Create composite curves for the 2D profile and a drive curve. The 2D profile and drive curve can be either open or closed.

2. Click General Edits displayed. 3. Click

flyout. The General Edits toolbar is

(General Edit toolbar).

4. Use the Create pattern from Wireframe option of the Pattern Edit dialog box to place the profile around the drive curve.

Variably offsetting curves Offset curves and surface curves such that the offset value varies at different positions.

In a surface with only two laterals, you can define the offset as a draft angle instead of an offset distance. See Also: Variably offset a curve (see page 12) Variably offset a curve 1. Create a surface or a curve. The curve can be either a wireframe curve or a composite curve, that is open or closed. The surface can be either a power surface or a primitive.



2. Click General Edits displayed. 3. Click Offset 4. Click

Grading shoes You can grade shoes by scaling the whole shoe up or down using a range scale factors. This is called Group grading (see page 33). You can grade shoes (or boots) in such a way that different 'zones' are scaled by different amounts (or fixed as unscaled) with smooth blending between. This is called Z (see page 34)one grading. You can use EVA grading (see page 38) to take into account the expansion properties of EVA foam when creating the mold cavity for the sole.

Creating a grading origin If you want graded entities to match each other at a particular point, 1. Create a workplane at required point on the original item. If there is no active workplane, the grading origin is considered to be World, at 0 0 0. 2. Grade the object as normal. The example below shows grading with the origin at the back of the heel.

Using the Grading Wizard The Grading Wizard lets you use Group Grading and the Zone Grading functionality from a single dialog box. To start the Grading Wizard, 1. Ensure that you the SoleDesign module is running and the model to be graded is open and selected.



2. Click Grading


3. Use the Grading Type options on the Grading dialog box (see page 29) to create different shoe sizes by selecting Group grading and Zone grading as appropriate.



Grading dialog box Use this to grade a shoe to give different sizes using Group Grading or Zone Grading.

Reference geometry selected (optional) - You can select geometry from where the increments will be referenced. When you select some geometry, changes to . In general, you will want to apply the increments to the internal dimensions of the sole and not the external dimension of the sole. In this case, you need to select the internal geometry as the reference geometry. In the figure below, the internal geometry is also shown outside the shoe for clarity. The reference geometry is used when converting between increments and scale factors when increments have been specified. If no reference geometry is specified, the overall size of the geometry is used Grading File - Select a grading file for the basis of your shoe sizing. Specifications for the following shoe sizes are provided:



French - Children's, Men's, Women's, Youth's. UK - Children's, Men's, Women's, Youth's. US - Children's, Men's, Women's, Youth's. - Save the grading table that you have modified as a .csv file. You should save the grading table to the shareddb folder that will typically be stored in C:/Program Files/Common Files/Delcam. Your filename will automatically be prefixed by PSGRADE_ and given a .csv extension. When you return to grading, you will find that new_grading has been added to the Grading file list. Select a standard - You can load a standard that contains the definition of width fittings and mid sizes. The available options are UK Mens Shoe and US Mens Shoe. The standards files are typically stored in stored as .csv files, typically in the C:/dcam/product/powershapeXXXX/file/grading folder, (where XXXX is the product version). The names of the standards files all start with PSGRADESTND_. You may create your own standard or customise an existing one. You should save your customised standards files to the shareddb folder with a filename that takes the form PSGRADESTND_name.csv. Destination - There are three possible output options for your graded model. New level - Each size will be saved to a new level on the existing model. Current model and levels - Sizes are saved to existing model and levels. Although this option lets you see all sizes together, the output can look rather cluttered if you are generating a lot of sizes.



New Model - Each size will be saved as a new model. The model name will take the form Graded_size_XX.psmodel where XX is the shoe size. Increments - This is the default option. Grading is defined by increments, based on the increments that are displayed in Parameters for Grading. Scale factors - Grading is defined by a table of pre-defined scale factors, based on the Main Size shoe. All shoe sizes that are larger than Main Size are scaled by a factor >1. All shoe sizes that are smaller than Main Size are scaled by a factor <1. Sizes First Size - Enter the size of the smallest shoe you want to create. Last Size - Enter the size of the largest shoe you want to create. Main Size - Enter the size of the shoe that is to be used as the basis of the grading. Main Step - Enter the step size for the shoe sizes. For example, to create shoe sizes 10, 10.5 and 11 you will need to set Main Step to 0.5. First Mid Size - Select a value from the drop down list to represent the narrowest fitting. The values that are available for the Mid Size drop down lists are defined by the file that you selected from the Select a Standard drop down list. US options will display sizing of AAAA - EEEE. UK options will display widths A - H. Last Mid Size - Select a value from the drop down list to represent the widest fitting. Basic Mid Size - Select a value from the drop down list to represent the standard width fitting that this model represents. Mid Step - Enter the step size for the shoe widths. For example, to create shoe widths AA, B, D and EE you would set Mid Step to 2 as shown below. Grading Type - Select the grading mode from the drop down list. Group is the only option currently available. Parameters for Grading - Grading parameters define the scale factors or increments to be applied to produce the different shoe sizes



Main sizes -The X, Y and Z boxes give the values that are used to calculate the scale factors or increments to be used to create the main sizes. The values can be modified manually by entering a value in the box. Mid sizes - The X, Y and Z boxes give the values that are used to calculate the scale factors or increments to be used to create the mid sizes. The values can be modified manually by entering a value in the box. Grading Table - This table shows all the grading and sizing information for the range of sizes that you have selected in the other sections of the dialog box. By default, the grading table will have the columns shown below In addition, is you have additional solids that you wish to use (for example, an airbag in a sole), an additional column will be displayed for solid. This allows these solids to use different scaling factors for a specific size. So, the sole airbag for a size 20 shoe may use the grading factors of a size 18 shoe.

Grade - Any shoe size that is defined by grading will be indicated by Yes by default, except the Main Size. To omit a particular size, select Yes on the relevant row with the right mouse button and select Modify to display the Edit Grade dialog box. You can also display this dialog box by double clicking the relevant row. Turn OFF the Grade option in the dialog box and close the dialog box. The Grade column in the grading table will be updated. You can select multiple rows using the normal CTRL and click technique. Size - There will be an entry in this column for every shoe size that falls in the range that you defined using First Size, Last Size, First Mid Size, Last Mid Size, Main Step and Mid Step. X - X value grade data for the selected size. If you have selected reference geometry, and the type of grading is set to Increments, this value will be the position relative to the reference geometry.



To change this value, select it with the right mouse button and selecting Modify to display the Edit Factor dialog box. Select another value from the drop down list, or enter a new value in the X Value box.

Y - Y value grade data for the selected size. If you have selected reference geometry, and the type of grading is set to Increments, this value will be the position relative to the reference geometry. You can modify this data using the Edit Factor dialog box. Z - Z value grade data for the selected size. If you have selected reference geometry, and the type of grading is set to Increments, this value will be the position relative to the reference geometry. You can modify this data using the Edit Factor dialog box. OK - Grade the shoe according to the parameters defined in the dialog box. Cancel - Close the dialog box without grading the shoe.

Group grading Group grading can be used to quickly produce many shoe sizes by scaling a selected shoe up or down. The example below shows the original, size 20 and two other sizes (16 and 27) that were obtained by grading the original.



Zone grading You can create different shoe sizes by scaling various portions of a single shoe. These portions are called zones. The portions not scaled are blended onto the scaled zones. In the example below, the following zones are scaled on the boot.

In the following figure, you can see the result of the zone grading.

When you are zone grading, you have more control over the blending zones if there are more control points on the surfaces. To create shoe sizes using zone grading Zone grading using the Grading Wizard Zone grading is available from the Grading Type options on the Grading dialog box. To create shoe sizes using Zone grading



Select Zone from the drop down list. Additional options are displayed in the Parameters for Grading section of the dialog box.

Editing the current zone You can edit the current zone in one of the following ways: button. When you select this, Select the Edit current zone the Edit Zone dialog box is displayed. Change the Upper Limit and Lower Limit by entering values in the dialog box and clicking Dismiss. Use the mouse to dynamically change the limits by dragging the individual zone boundaries. Shift the entire zone by holding down the SHIFT key and dragging the zone to a new location. Creating a new zone You can create a new zone on your model in one of the following ways: Select the Create new zone button. A new zone will be added to your model and the drop down list. The grading table will be updated to include the new zone and the scale factors of the current zone will also be copied.

Hold down the CTRL key and drag the mouse to make a copy of the current zone (including the scaling factors)



Deleting the current zone Select the Delete current zone

button. Zone 2 will be added to 5. Select the Create new zone your model and the drop down list.

6. Adjust the zone boundaries and the scaling factors for the zones as required. Click OK to apply zone grading to your model.



EVA grading Many footwear manufacturers use a flexible shock-absorbing foam called EVA (Ethylene Vinyl Acetate) which is made up of tiny air bubbles. When EVA is injected under pressure the air bubbles are compressed. Opening the mold lets the bubbles expand and the molded shape grows considerably in size. The mold designer must take the expansion properties of the material into account when creating the mold cavity. Because the sole thickness varies along the length of the sole the expansion percentage will vary accordingly. When using EVA grading you can specify slices that cut the model in a particular direction. apply a specified expansion to each slice in the specified direction create slices and specify expansions in any or all of the X, Y and Z axes create planar slice

or a curve slice based on an extruded curve

Starting EVA grading 1. Select Module from the PowerSHAPE menu bar and select Crispin from the drop down menu.



2. Select SoleDesign. 3. Open a model and select the sole geometry to be graded. The geometry can comprise of surfaces, solids, symbols with triangle data, curves and composite curves. 4. Click on the SoleDesign toolbar to display the EVA grading dialog box (see page 39).

5. Use the options on the dialog box to create the graded sole. EVA Grading dialog box Use this dialog box to define the grading for an EVA sole.



Destination - There are three possible output options for your graded model. New level - Each size will be saved to a new level on the existing model. Current model and levels - Sizes are saved to existing model and levels. Although this option lets you see all the results of using different values, the output can look rather cluttered if you are generating several versions.

New Model - The graded model will be saved as a new model with the name EVA graded items.psmodel Direction - Select from X, Y or Z to define the direction that the current slice will be created. On the following model, X has been selected as the Direction.

Slice - Select the slice number from the drop down list. When additional slices are created, they are added to this list. Position slice - Enter the position of the current slice. If you create additional slices, the positions are defined by the value in Spacing (default 10) If you are using a curve selection, this option is not available. - Delete current slice.



- Toggle direction of curve extrusion. When using a curve to produce the slice, the curve is extruded orthogonal to the axis. In most cases the most appropriate direction is automatically selected, but if required, you can you can toggle the extrusion to see the only alternative. Scale(%) - Enter the expansion factor for the current slice as a factor. If you want the expansion factor to be unchanged, leave this option set at 100. When you create a new slice, it is automatically given the expansion factor of the current slice. - These buttons let you apply the Scale factor at or between the slices as follows: applies the Scale factor between the slices.

In the following example, Scale was set to 70; that is a shrinkage of 30% between slices 2 and 3

applies the Scale factor at the slice you have selected in the Slice drop down list.



In the following example, Scale was set to 70; that is a shrinkage of 30% at slices 3

You can add one or more slices relative to the current slice by using Spacing, Number of slices and as follows: Spacing - Enter the spacing of the additional slices. Number of slices - Enter the number of additional slices to create, relative to the current slice. - Add slice(s). Clicking this will add the appropriate number of slices relative to the current slice. The new additional slices will be added to the model and also to the Slice drop down list. The slices will be spaced according to the value you specified in Spacing. Existing slices will be renumbered as appropriate to avoid duplicates. You can also graphically add and select slices as follows: To copy a slice - Hold down the CTRL key and drag an existing slice To reposition a slice - Drag the slice to the new position To select a slice in the current direction - Click the appropriate slice to make it current The correct numbering of slices will always be maintained, so adding and repositioning slices may cause existing slices to be renumbered to maintain integrity. EVA grading example This example shows how to apply EVA grading along the x-axis only. You can create slices and specify expansion factors in one or more axes. 1. Ensure that the model to be graded is open and selected.



2. Select EVA grading from the SoleDesign toolbar. The EVA Grading dialog box (see page 39) is displayed and default slices created in the X direction are drawn on the model. The current slice is 1 and the end slice is 2.

3. Using the EVA Grading dialog box (see page 39), click to add a new slice using the default values. The new slice becomes 2 and the end slice is renumbered as 3

4. Drag slice 2 to a new position on the current axis.



5. Use to copy the current slice. This will create a new slice with the same values. The slices will be renumbered to avoid any duplication.

6. Specify the following expansion percentages: 70% for slice 2 75% for slice 3 7. Click OK to create the graded sole. The default Destination is New Level (on the current model), so the model will look similar to the one below.

You can use levels to see the original sole and the EVA graded sole separately



Tips on using EVA grading If you want a region to be unaffected, it needs to be surrounded by two slices that have 100% as the expansion factor. If two slices have expansion factors of X1 and X2, the result will be a scaling of sole between the two slices by their average. The curve used to specify a curve slice may be a feature line.

The slice for the above model is

Suppose we specify 70% expansion along the curve 75% along the bottom 70% along the top The region between slices 2 and 3 will be scaled by 70% and the lower region by 72.5%



Heel Creation Creating a heel The Heel Creation option is used to create profiles that can become the seat or the base for a new heel. This tool provides five types of profile that can be customised by editing the parameters for the profile. Once the parameters have been entered, the Edit Profile tab can be used to adjust the scale or the position of the profile. 1. Click

The remaining composite curves can be considered as Other Profiles. Dismiss - This exits the command, without creating the heels and removes the wizard from the screen. Next – This displays the second page of the Heel Grading wizard.



Second page of the Heel Grading wizard This dialog box is used to enter the grading for the heel.

The red bullet is at the top of the basic number column. The dimensions of the selected geometry are displayed in this column. As you move the cursor over the figures in the grid, the relevant dimensions are highlighted on the image in the wizard. Using the grading parameters form There are six buttons on the grading parameters form: Save the increments you have entered into the grid as a .hgd file. Open a .hgd file of previously created increments. The dimension setting will automatically be set to incremental. Incremental dimensions. Absolute dimensions. This is the default dimension setting. Use angle. Selecting this row activates row B in the parameter table.



Use projection. Selecting this button activates row C in the parameter table. Linear grading. Use this option to create a heel similar to the one below.

Non-linear grading. Use this option to create a stiletto-type heel like the one below.

Delete number. This deletes a column in the parameter table and is used to reduce the number of sizes. Add number. This is used to add a size to the parameter form. The grading parameter form has the following features: If you move the cursor over the size number, it changes to a red bullet . Clicking on the size number of the grid allows you to change the Basic Number. If you use the mouse to 'hover' over the parameters on the grading parameter grid, the relevant dimensions are highlighted on the image in the wizard. You can edit the individual cells of the grid by double-clicking in the cell.



You can lock a particular row of parameters using the padlock buttons to the right of the grid. The default is unlocked. A number of additional parameters can be accessed by clicking on the Advanced button. Standard grading parameters - the standard parameter grid is shown below.

This allows you to enter values for XUC, YUC, XTH, YTH, H, A, B and C. These dimensions are defined on the following diagrams:

Side view

Top view

Advanced grading parameters - A number of additional parameters can be accessed by clicking on the Advanced button.



D is the displacement along the y-axis. Once a new heel has been created, the displacement factor will move the heel along the yaxis. This will allow the range of created heels to be seen alongside one another. If an incremental value of 100 is entered for D, the resulting model might look as follows:

H(X) is the height (z value) from scaling factor is applied to x (in case the base dimensions are locked). H(Y) is the height (z value) from which the scaling factor is applied to y. H(Z) is the height (z value) from which the scaling factor is applied in z.



H(TH) is the height from where the heel will be graded with the same scale factor used for the seat and front seat. Below this value, the heel is graded using scale factors that are calculated according to the chosen algorithm (linear or non-linear). The H(TH) dimension is shown on the diagram below.

Icod, Ycod and PQ are parameters to control scaling of the tail of the heel (not implemented). Advanced - Use this to toggle between show and hide the additional parameters. Dismiss - This exits the command, without creating the heels and removes the wizard from the screen. Back - Use this to return to the previous page. Preview – This scales the composite curves you selected on the first page (seat, front seat, base, front base and other profiles) and displays then superimposed on the original heel. Before selecting this button, ensure that there are values in all the cells for all the required shoe sizes. Next - This displays the third page of the Heel Grading wizard.

Third page of the Heel Grading wizard This dialog box is used to select the required method of saving the output.

Output



There are two options for saving the model. Use the radio buttons to choose the option you require. Output on Separate Levels – Select this to output the new sizes on different levels of the same model. If you create 3 new sizes (for example sizes 1, 2 and 4), the output will be the first free (unused and unnamed) levels. So, if levels 20, 33 and 41 were free, the models will be output to those levels. The name of the output levels will reflect the sizes that have been created. So in the example above, the output levels would be named Size1, Size2 and Size4 respectively. Output on Separate Models –Select this to output the new sizes as separate models. Enter a model name in the text box. The new sizes will all have a name of the format filename_4, filename_5, filename_6 etc., where filename is the model name you entered in the text box and 4, 5 and 6 represent the new shoe sizes. Milling Options There are two Milling Options. Use the check boxes to choose the option(s) you require. Create Workplanes – This creates workplanes at the seat back point of each heel. These will be used when machining the heels. In the figure below, the displacement parameter (D) was set in the Advanced parameters to display the heels individually.



Align along Seat Back Point – This aligns the heels using the seat back point as the alignment point. The figure below shows a set of heels aligned along the seat back point. The displacement parameter (D) was set in the Advanced parameters to display the heels individually.

Back - Use this to return to the previous page. Apply – This creates the range of graded heels Dismiss - This exits the command, without creating the heels and removes the wizard from the screen.

Editing a Last The Last Editor lets you make changes to an existing last by altering parameter values associated with the last. To use Last Editing, 1. Ensure that you the SoleDesign module is running and that you have a model of a last open. You can create the last using the Last Identification Wizard. (see page 70) or load a library of lasts that are supplied with PowerSHAPE.



2. Select Last Engineering Mode


The Last Engineering toolbar will be displayed. 3. Click

(Last Engineering toolbar).

4. Use the Last Editing dialog box (see page 78) to change the parameters of the last. Last files You can import last and style files from MIND software. You can load a library of lasts by running the macro called load_lasts.mac that is supplied as part of PowerSHAPE. It is typically located in C:\Program Files\Delcam\powershape7240\file\examples Using the Last Editor You use the Last Editing dialog box to change the parameters of the last. The parameters are colour-coded on the Last Editing dialog box (see page 78) as follows Stick Length shown in yellow Toe Spring shown in cyan Heel Height shown in red Girth shown in green Parameters can be changed by entering a new value or using the appropriate slider. You can display the calculator by clicking the right mouse button in the box containing the parameter value. As you change a parameter, the values on the graphic on the Last Editing dialog box are updated to reflect the changes you make. Last Editing dialog box Use this dialog box to alter the parameters associated with a last.



When the Last Editor is opened, the levels containing the key curves and key points on the last are turned OFF. - Displays the Move last before editing dialog box. Use the slider on this dialog box to move the last copy away from the last that is being edited, so you can see both the lasts. Stick length - The stick length is the overall length of the last. Changing the stick length affects the values that are displayed for the Toe spring, Heel height and Girth parameters. If you update the Stick length without locking associated parameters, the last is scaled in all three directions.



- The current value for the Stick length is shown in the box. Use this slider to adjust the value, or enter a new value in the box. Allowable values are in the range 1 to (twice the current stick length). So for a stick length of 250, the value you enter must be in the range 1 to 500. The Stick length option that you choose determines the way that the parameter is applied. Toe spring and heel height - If locked, editing does not affect the last in the Y direction. Last width - If locked, editing does not affect the last in the Z direction. Back of last - If locked, only the front part of the last is scaled; the back of the last is unaffected by scaling. Toe spring - The vertical distance between the base plane and the toe point of the last. Use this option to update the parameter that defines the Toe spring. - The current value for the Toe spring is shown in the box. Use this slider to adjust the value, or enter a new value in the box. Allowable values are in the range 0 to (toe spring value of the last when the stick length is set to its maximum). The Toe spring option that you choose determines the way that the parameter is applied. From vamp point - When the Toe spring is changed, the change in height will be graduated between the portion of the last that is between of the vamp point and the toe point. From girth - When the Toe spring is changed, the portion of the last that is changed is determined by the girth points. The change in height will be graduated between a plane passing through the three girth points and the toe point. Heel height - The vertical distance between the base plane and the heel point. Use this option to update the parameter that defines the Heel height. - The current value of the Heel height is shown in the box. Use this slider to adjust the value, or enter a new value in the box.. Allowable values are in the range 0 to (heel height value of the last when the stick length is set to its maximum). The Heel height option that you choose determines the way that the parameter is applied.



Heel seat length - Use this to adjust the region of the heel seat that will be affected by the heel height. Stick length - If locked, the Stick length is not affected as the height of the heel is adjusted. If unlocked, the Stick length is changed as the height of the heel is varied. Girth - This option is used to update the girth of the last. Changing the girth also affects the Stick length, Toe spring and Heel height. - Change the girth of the last by using the slider or enter a value in the box. Affected Area - Use this to specify the region of the last that will be affected by the girth edit. This is the distance that decides how much the selected point on the last will be distorted as the distance for the girth curve increases. If the affected area is small, the distortion will be extreme, but if the distance is larger, the change in girth will be more gentle The following options let you define how the change in girth will be applied. Overall - This is the default option. Any change in girth will affect all directions. By width - The girth is only affected in the Y direction - the width. The height of the girth will remain the same. Change only on side surface - Only the side surface is affected, base surfaces remain unchanged. Use this option if you have already designed a sole for a last and do not want the last to change where it would cause a mismatch between the sole and the last. It will ensure that the girth change will affect only the side surface of the last (the upper) . - Undo the last edit. - Redo the last edit. Restore - Restore the last to its original settings. OK - Accept the changes and close the dialog box. Cancel - Cancel the changes and close the dialog box.
