Hi all, I've been working on re-tooling the iGeom interface. As a part of this, the iGeom will now only return RefVolumes. However, in many cases it is much easier to use bodies to modify the geometric model. I've been attempting to use the RefVolume method get_body_ptr() to retrieve the volume's body and use that to modify the model, but when I attempt to use the method my programs often seg fault for some unknown reason. I'm using the master branch of CGM built with Cubit 14.0. All tests pass except the one I've attached which creates a body using the geometry query tool, get's the RefVolume for the body, and then attempts to retrieve the body from the RefVolume (where it fails) and delete it. If there's some misunderstanding I'm having about the purpose of any of these functions please let me know! Cheers, -- Patrick C.
