I have question about using .ifczip in blender.
I always use ARCHICAD and I wanna export ARCHICAD mesh data to blender for rendering.
I found the solution by exporting .ifczip in ARCHICAD and importing it in blender.
However I have a bit problem.
When I render image the meshes , There are unknown meshes which is not displayed in Viewer.
It seems to generate at window and door position in ARCHICAD.
Do you have any ideas to solve ?
