i am trying to convert Ifc file to Step file format . for step files i need ifc transformation.
from the IfcClosedShell, i got face points but i need transform this points from IfcAxisPlacement3D (cartesian Point , ref Direction , Axis Direction.)
Matrix for transfer face Points to Original position.
What are you using to parse the IFC and generate geometry? if you're not using anything beyond parsing the STEP file, be aware there are existing libraries out there to do the heavy lifting such as https://github.com/xBimTeam/XbimEssentials
