CGR Derived Output for Downstream Applications

When generating CATIA Graphics Representation (CGR) files as optional derived output for use in downstream apps, you must establish certain 3DEXPERIENCE parameters and refinements pertaining to the CGR files.

This page discusses:

Global Configuration Object Settings

To use CGR files in other 3DEXPERIENCE apps, the following Global Configuration Object (GCO) parameters must be specified before attempted CGR creation during a Save operation. To modify the GCO in the thick client user interface, you must have the privileges of an Integration Administrator.

NXUPS-GlobalConfig NXUPS Required Value
IEF-Pref-MCADInteg-SelectedDerivedOutput (DEFAULTVALUE)cgrViewable
UGDerivedOutputOptions

cgrOutput|sag=0.0,delete_on_checkin=yes

cgrViewable|delete_on_checkin=yes

UGDerivedOutputOptions

Note that these variables directly control the accuracy of the tessellation of the native NX file for subsequent creation of the CGR file. The tighter the values, the greater the accuracy of the CGR file. However, as the tolerance increases (values getting smaller) during the creation of the tessellated file, the native NX file size increases significantly. This increases the time required for calculating the CGR and storage in 3DEXPERIENCE. Use caution when increasing these values.

Recommendation: Use the above mentioned default settings.

The units of the GCO variable UGDerivedOutputOptions are in MM, regardless of the NX session units. Additionally, the CGR generated and stored in 3DEXPERIENCE is also in MM units.
