Hello,

I load model from catiav5 file, with option TranslateFreeSurfaces: true.

How can I find bodies with free surfaces in ACIS scene? Probably they have some spectial attribute.

Hello Megapixel,

In ACIS we have the is_solid_body and is_closed_solid_body helper functions that can help you determine this. Please see

for additional details.

Thank you for your reply.

At this I use criterion free surface is equal body of only one face.

But in some cases (ProE file format) acis translate body consisting of several face when the flag translate_free_surfaces.

In other words not closed body with several faces can't be definetly recognized as "free_face".
