Sets the rules that are used to calculate both the X and Y sizes of the compensating plate.
The default values/settings indicated on the window are those that exist when the Supports application is first installed.
Click Reset to revert the Supports Compensation Sizes window to the default values/settings.
Changes made are only applied to the database when Apply is clicked. To keep the changes the Save Work operation must be performed.
Click Cancel to close the window. If changes have been made, but not applied, a window displays asking if the changes are to be applied before exiting.

The Supports Compensation Sizes window contains two tabs for specifying separate rules to calculate the X and Y sizes of the compensating plate.
The General Rule is used when a rule for a given support type is not defined.
The Default Value field defines the default X and Y sizes of the compensating plate.
Rules can be created for specific support types, input the support codes into the support code field, separated by a space. An asterisk can be used to identify all support types. If two rules are defined for the same support type, the first rule in the list for that support type is used and the second is ignored.
A rule must always be a Programmable Macro Language (PML) expression that returns a REAL value upon evaluation. If the expression contains references to attributes or properties, the expression is evaluated against the ANCI of the support. Therefore it can contain any attribute or property which is available on the ANCI element.
To access the width of the General Section (GENSEC) supporting the ANCI, the syntax 'VVAL( !WIDTH)' can be included into the expression. The profile width in this context is the width of the GENSEC face below the ANCI depending on the profile rotation and may not necessarily correspond to the catalog property WIDT.
If the evaluation of the rule expression fails, then the explicitly set default value is used instead.
To add a new rule to the list of available rules, click Add Entry to display the Add Entry window.

You can populate the Support Codes and X-Size Rule or Y-Size Rule fields with the relevant rule values.
Click OK to add the rule to the list of available rules or Cancel to discard any changes and close the Add Entry window.
Click Remove Entry to delete the currently selected rule.
