Hi, STEP and IFC use the same syntax (P21). I know assimp could read IFC files but nothing about STEP. IFCLoader uses STEP reader classes and generated express data (see...

Hi, had the same problem. Setting "USE_EXPLICIT_INSTANTIATION" to "OFF" solved it for me. Greets, Patrik

Not sure if I understand your question. You could load each model in its own world and merge these worlds. Was this the question?

What do you mean with "fully display"? Have you tested both models if the contents are valid?

Ah ok, take a look here: void GLC_World::mergeWithAnotherWorld(GLC_World& anotherWorld) { GLC_StructOccurrence* pAnotherRoot= anotherWorld.rootOccurrence(); GLC_StructOccurrence* pRoot= rootOccurrence(); if (pAnotherRoot->childCount() > 0) { QList childs= pAnotherRoot->children(); const int size= childs.size(); for (int...

You could use the instance (GLC_StructInstance) from an occurrence. It has methods for move, translate and direct matrix assignment.
