I have the following problem when exporting an XDE document to STEP-AP via STEPCAFControl_Writer in OCC 6.3:
When there are nested assemblies, (e.g. assembly1 is father of assembly2), the child-assemblies are exported only if they have a sibling (which is in my tests a simple shape).
So, when the structure in the XDE document is this:
the assembly2 and the shapes are not exported to STEP.
But when the structure is this:
| +-- shape1
| +-- shape2
then everything is fine.
Is this a common problem or just mine? Does someone have a suggestion?
Thanks for taking a look!
