File BIM – IFC e IFCxml

L’importazione di modelli BIM è supportata nei formati IFC e IFCxml. Durante l’importazione gli elementi IfcWall vengono meshati automaticamente con elementi quad in mesh strutturata. La dimensione della mesh può essere specificata nelle opzioni del programma. Le tolleranze nella posizione di finestre e porte non supera la metà della dimensione della mesh.

È supportata la lettura di:

• IfcBeam
• IfcColumn
• IfcWall
• Sezioni trasversali come SweptSolid, Curve2d e MappedRepresentation.
