CATIA V5 DRAFTING IN AUTOMOTIVE CATIA DRAWINGS

1. OBJECTIVE Creation of Drawing similar to reference PDF file and as directed by client. 2. INPUT FROM CLIENT A. Reference PDF file B. Drawing Template (already shared by client at the start of the project) C. Word file (for Specific Drawing instructions given by client) D. CATPART/CATASSEMBLY E. Excel File For 2d points import (If required) F.

Word File for Export and Import of points from Cat Part to Excel file.

G. CATIA V5 R19 (Software) 3. WORK PROCEDURE A. FOR CREATING FRONT VIEW i. First Open the Template in which Drawing is to be made. Then do save as by name of the part, whose Drawing is to be made. ii. Open that PART. iii. In the View Toolbar click Front View option.

iv. In every Part there is FEATURE FOR 2D DRAWING. Under this option there is PLANE FOR FRONT VIEW. Select this plane for ge tting Front view (If plane is not given then try to get front view similar to reference PDF using XY/YZ/ZX plane or any main surface of the part)

TCS Internal

Page 3 of 46


v. The Catia window automatically switches to drawing (Front view is seen inside Green Box).

vi. Click anywhere in the drawing if the view inside the green Box is needed, else change the view orientation by rotating or flipping the Compass next to the view. vii. By clicking on the Triangle (shown in the above fig.), view can be flipped and by clicking on the curved arrow, view can be rotated, in either direction. viii. The view cannot be edited after it is generated. B. FOR CREATING PROJECTION VIEW i.

Activate the front view and from the View Toolbar click on the Projection View option.

TCS Internal

Page 4 of 46

There are 4 possible options of creating projection view i.e. Left view, Right view, Top view and Bottom view. These are obtained when cursor is moved towards Left, right, below and above the vie w respectively.

iii.

Not necessarily that all the projection views should be created, it depends upon the requirements of client.

iv.

The view cannot be edited after it is generated.

C. FOR CREATING SECTION VIEWS i.

Select the view from which section view is required.

ii.

In the View Toolbar, go to Sections and Select Offset Section view

iii.

Click on the starting point and then double click on the end point.

iv.

2. Aligned Section view

: Create the profile by clicking on the points

(more than 2 points on the main view ) through which the view has to pass.

3. Offset Section cut

4. Aligned Section cut

: Only Hatched portion will be visible.

: This view is generated similar to Aligned Section

view.

Automotive Catia Drawings W. MISCELLANEOUS i.

A view is not active, when it is enclosed in blue dotted rectangular box

View is activated by double clicking on it. Then it becomes enclosed in red dotted rectangular box. This is the range of the view and its content (i.e. dimension we put, annotations we create, etc...)

ii.

Whenever view is generated, by default view axis (refer below figure, blue L shaped) is also visible when we double click on it.

Select it and Hide it using Hide option

.

Selecting this turns orange in color

then click on Hide option

.

Now the view appears as shown in below figure. It is mandatory that axis system is hidden by this method only (required by

TCS Internal

Page 43 of 46

Automotive Catia Drawings client).

iii. Always keep in mind that whatever tools used other than view generation, respective view should be activated before using the tools. iv. Double click the tool to perform action more than one time. v.

Geometrical Tolerance can be attached to Dimension also

Text and geometrical tolerance can be fixed with the dimension by Creating positional link and orientation link. This option will come by right clicking on text or geometrical tolerances. vi. Arrows of the dimension line should be outwards when the dimension value is outwards from the element. (Required by Client)

If the value lies inside the dimension line , then arrows will be inwards.(Refer below figure)

TCS Internal

Page 44 of 46


vii. Curve Edges have more than one anchor point. Press Ctrl Key (Dimension will be stationary)place the cursor on Yellow Dot

, possible anchor points will

get visible in blue, drag this yellow dot to change the anchor point.

viii. By default view is generated with its view name showing scale also. ix. Remove Main View Name i.e. Front view, Right View, Left View, Top View, Bottom View, and Auxiliary View as its scale is mentioned in the TITLE BLOCK. Keep View name of Section View, Detail View as its scale will be different from the main views or refer to PDF file given. x.

Lock all the views before delivering drawing to the client.

xi. Do the CATDUA and save the file before delivery. xii. Save the PDF format of the CAT Drawing made in the same folder.
