The following workflow can result in a conversion of NURBs information into polygon data:
- Convert a .catpart with DELTABATCH/DELTAGEN R2018x RF1 into 3xf file format
- Load the converted .3xf file into DELTAGEN R2017x RF1
- Save the scene in DELTAGEN R2017x RF1 as .csb file
- When you reopen the csb file, all geometries are now polygon objects
We recommend to avoid the above mentioned very rare workflow as this ist not the intended workflow.
