Hello You could use entity > IObject_DG > GetHash(), which would produce a unique 32 bit integer. But the hash has lifetime of the application and the same entity loaded in different apps simultaneously would have different values. A reliable way would have a data structure which contains the entity...

Not really. This is implemented in the BRep face structure. Surfaces represent the mathematics (equations) which define its geometry. Trimming is done with wires after the surface has been wrapped into a face.

Another way is via IBRepBuilder_DG. Search samples for IBRepBuilder_DG to find a way to get it. IBRepEdge_DG IBRepBuilder_DG.CreateEdge4(ICircle_DG circle) > IBRepWire_DG IBRepBuilder_DG.CreateWire() > IBRepWire_DG.AddEdge(IBRepEdge_DG edge) IBRepFace_DG IBRepBuilder_DG.CreateFace7(IBRepWire_DG wire)

There are many ways for doing this. The minimum code way is using IStdShape_DG.Disk(). It will create a disk in the xy palne, which can be moved around. I have hacked PatchForm_Load() of the installed C# Patch sample to check: //Before m_iEntity = iStdShape.Cylinder(m_baseRadius, m_topRadius, m_heig...

Certainly. There are few options. In the current v7.4 you can use planar clipping demoed in the Planar Ops sample. You could also clip by another surface defined interactively. It can be a cylindrical, spherical, etc. or like extruded prism defined using overlays with mouse clicks. Or you could buil...

Hello Augustin Not right now, but it is high in priorities. We will consider your question as a vote. .brep is the only format we support, apart from .mdg, which can handle both parametric and mesh objects. Currently objects with other than BRep geometry are skipped during .brep export. Thank you fo...

Hi Jason.
It should work if you just delete the wire.

It worked in my quick test where I added
iFace.RemoveWire(iWire);
as the last line in FaceForm.AddInnerWire() of C# Face

We have fixed this in today's 7.3.5649 update.

The bug was only in DGKCn6. Other controls were OK.

V7.3 has no interface difference with 7.2, so upgrading is a no brainer. But still, let us know if you need a fix in 7.2 as well.

Regards

Sorry about the late reply.
We are looking into it.
Thanks for reporting

We have posted a fix in update 7.3.5638.
