Apply Size Rule – Applies the size of the selected component to the attached size of the previous component. Three settings are available: Show Options, Automatic, and No. In the example above, a 1inch flange is being added to a 3-inch pipe. When this rule is set to Show Options, you receive the prompts shown in the image on the left (1). When this rule is set to Automatic, the size of the component is changed to match that of the pipe, as shown in the image in the middle (2). When this rule is set to No, the size of the flange stays the same size as the flange size selected, as shown in the image on the right (3).

Apply Specification Rule – Applies the specification of the selected component to the attached specification of the previous component. Three settings are available: Show Options, Automatic, and No. In the example above, a 1-inch 300 lb specification flange is being added to a 1 -inch 150 lb specification pipe. If this rule is set to Show Options, you receive the prompt shown on t he left (1). If this rule is set to Automatic, the result is similar to the image shown in the middle (2), where the specification is changed to be the same as the pipe. If this rule is set to No, the result is similar to the image shown on the right (3), where the specification remains unchanged as illustrated by the green color of the 300 lb specification.

Apply End Type Rule – Checks the end type of two inserted components for a match. Three settings are available: Show Options, Automatic, and No. In the example above, a 2-inch globe valve is being added to a 2-inch pipe. If this rule is set to Show Options, you receive the prompt shown on the left (1). If this rule is set to Automatic, you receive a prompt similar to the one shown in the middle (2), indicating that adding a globe valve to a beveled piece of pipe without a flange violates the end type rules. If this rule is set to No, the software adds the valve without displaying any prompts, as shown in t he image on the right (3).

Apply Pipe Length Rule –Uses the Specification Editor settings for minimum and maximum length of pipe allowed. Three settings are available: Show Options, Automatic, and No. In the example shown above, a 3-inch length of pipe is being drawn. If this rule is set to Show Options, you receive the prompt shown on the left (1). If this rule is set to Automatic, the pipe is extended to 6 -inches, as shown in the image in the middle (2). If this rule is set to No, the size does not change and a 3-inch length of pipe can be drawn, similar to the image on the right (3). Apply Weld Insertion Rule – Controls the automatic placement of weld gaps. Two settings are available: No and Automatic. If this rule is set to No, weld gaps are not placed automatically. If this rule is set it to Automatic, weld gaps are placed automatically. When setting the rule to Automatic, you can specify whether it applies to Buttweld, Socket Weld, or Both.

Piping Rules Apply Gasket Insertion Rule – Controls the automatic placement of gaskets when a set of components requiring gaskets are placed in the drawing. Two settings are available: No and Automatic. Only flanges that have a pair or a valve attached will have automatically added gaskets. This can be seen in the image at the left. If this rule is set to No, gaskets are not placed automatically. If it is set to Automatic, gaskets are placed automatically when they are required. Apply Bolt Insertion Rule – Controls the placement of bolts in the drawing when components requiring bolts are placed. Two settings are available: No and Automatic. In the drawing to the left, the bolt is represented by the letter B that is lying down perpendicular to the gasket. If this rule is set to No, bolts are not placed automatically. If it is set to Automatic – bolts are placed automatically when they are required.
Apply Trimmed Elbow Rule – Allows you to place trimmed elbows in the model. The image above shows a trimmed elbow and how to identify it in the Component Edit dialog box. Two settings are available: No and Automatic. If this rule is set to No, trimmed elbows not allowed. If this rule is set to Automatic, trimmed elbows allowed. Apply Pipe Healing Rule – Heals the pipe when a component within a section of pipe is deleted. The images at left show a tee with weld gaps. These are being deleted and then the pipe heals itself. There are two options: No, which does not allow pipe healing, and Automatic, which allows pipe healing.

Apply Branch Table Rule – Controls whether the software checks the Branch table when branches are inserted into the drawing. This is a valuable tool when yo u are drawing reducing branches because it ensures that you are drawing valid branched components. Two settings are available: No and Automatic. When this rule is set to Automatic, the software checks the Branch table, as shown in the example shown above. If this rule is set to No, then the branch table is not checked.
Apply Flange Insertion Rule – Controls how flanges are inserted into t he model. If this rule is set, a flange is automatically placed in the drawing when required. The image above left illustrates how the piping continues on when you manually insert a flange while routing. The image above right illustrates automatic flange placement when the rule is set. There are a number of options available for this rule. The main options are Automatic and No. When this rule is set to No, flanges are not automatically inserted into the drawing. When this rule is set to Automatic, the type of flange you have specified is automatically placed in the drawing when required. An option that allows the software to place flanges based on the defined specification is also available. For more information, see Apply Flange Insertion Rule in the CADWorx Plant Users Guide .

Piping Rules
Apply Bolt Hole Orientation Rule – Applies the angle of the bolt holes based on three different selections in the rule.
Automatic – 1 Hole (image on the left)
Automatic – 2 Holes (image in the middle)
Show Options – Specify Input Angle (image on the right).
In each image, the red line denotes the center of the flange and how the holes correspond to that center. The last image shows the angle as set at 15. This rule can only be viewed in 3D Enhanced mode.
Apply Pipe End Prep Rule – Controls the application of the Pipe End Prep rule. Three settings are available: Show Options, No, and Automatic. When this rule is set to Show Options, you receive the prompt as pictured here. This allows you to decide whether to set the Pipe End Prep. If you do not want to receive this prompt, select No. This does not prep the end of the pipe. However, selecting Automatic preps the end of the pipe automatically without displaying any options.
Center Line – Turns on and off the centerline. The e xample on the left shows an image without a center line.
