Close and Offset Primitives

This task shows you how standard close and offset primitives are migrated into CATIA V5 using the option CATIA_SPEC. At the end of the task you will find a table presenting restrictions.
Open the document CLOSE+OFFSET.model in CATIA V5.

  1. Apply a Check AS SPEC on *SET1.

  1. Copy and Paste Special *SOL1 into another CATPart document using the CATIA_SPEC option and update your document to compute the geometry.

You have access to the model's geometry and specifications. Therefore, you can now modify each feature of the V5 CATPart document.


Under certain conditions, Close and Offset primitives are converted into solid datum: Note the following restrictions:
Primitives Conditions

V4 to V5 Migration


Offset *SKD as parent Solid Datum
Close open *SUR as parent Solid Datum
Close *FAC as parent Solid Datum

To sum up:
