Hi!
I programmatically made a polygon-object and a hypernurbs-object. Now I want to put the polygon-object under the hypernurbs-object and return the hypernurbs. I tried it with poly->InsertUnder(hypernurbs);, but for some reasons in Cinema 4D I can only see an empty object.
How is it possible to do that? -

Hi!
Didn't work with the Obj.-Manager, but I thought, to put it under another object, you have to use a member of the BaseDocument.
Try InsertObject and check the members.
Bye!

If I do that, Cinema 4D crashes.
This is my code:
copydoc->InsertObject(hypernurbs,NULL,NULL,FALSE);
copydoc->InsertObject(poly, hypernurbs, NULL, FALSE); -

I don't know, but I could imagine, that you have to "refresh" the ObjectManager. Means you have to add EventAdd() or something else like a Update_Message (MSG_UPDATE) after your first InsertObject.

Make sure that you haven't *already* inserted the object before calling InsertObject()! If you need to RE-insert an object it MUST be first removed:
poly->Remove();
copydoc->InsertObject(poly, hypernurbs, NULL, FALSE);And EventAdd() is required after such an operation as inserting objects into the document.
Sometimes this is more appropo as the third argument can be tichy:
copydoc->InsertObject(poly, hypernurbs, hypernurbs->GetDownLast(), FALSE);
As a final check, verify that copydoc, poly, and hypernurbs are VALID pointers!!! Specifying invalid pointers as arguments is an inevitable crash.

At least got the error: The Hypernurbs-Object is not generated (!hypernurbs is true)

If I'm correct here, you need to allocate as Osds instead:
BaseObject* hypernurbs = BaseObject::Alloc(Osds);
This is the new form of HyperNURBS.

The methodology might be a bit shaky for GetVirtualObjects(). You're returning 'poly' but also inserting it into copydoc. It can't be owned by two things simultaneously without repercussion. If the intention is to return the hypernurbs result, then you'll need to do CurrentStateToObject() (which is usually not possible here but in another document it may be).
