[cgma-dev] Observer question?

[David Thompson]

Hi Jane,

> As Tim said, after boolean operation, the engine determines which geometry get changed. And if you see GEOMETRY_TOPOLOGY_MODIFIED, you definitely need to call OCCBody::update_OCC_entity to get them synched. 

Thanks, that's very helpful to know. I was hoping that CGM provided some functionality similar to this across all the geometry engines, but this is the next best thing.
