I'm getting crazy. I want to cut an object and insert it as an child to an null object. Here's my code:

BaseObject* op = doc->GetFirstObject();  
BaseObject* wallsNull = BaseObject::Alloc(Onull);  

After executing this, my whole objects of the scene are inside the "wallsNull" and not only the first one. Also cinema freezes.
What I'm doing wrong?

Edit: Cinema doesn't freeze but I can't close it.

You can only insert a new object once into the document.  If you want it to be at the root, use the first doc->ObjectInsert() call.  The second call is gibberish. You cannot insert op underneath the object your are inserting.  If you want that then you have to remove op and insert under it:

doc->InsertObject(wallsNull, nullprt, nullptr);
doc->InsertObject(op, wallsNull, nullptr);

So, removing op frees it from the document's hierarchical chain so that you can then reinsert it into the document where you want in that hierarchy.  Understand?
