Recently I was working on a filling element that was required to fill in between the concrete slab and an architectural floor. The geometry of the floor wasn't traditional (flat surface). Therefore I used the 'Modify Sub Elements' option to define various heights to different parts of the element (as you can see in the image below).
Everything worked fine until I exported it to IFC format. The geometry is deformed when exported into IFC. Don't know the reason why. I've tried exporting in other versions of IFC (2x3, 4, etc.) along with changing the detail level to 'high' in the export options and still didn't achieve a complete form of the object, see image below.
Excessive lines began to appear on some parts of the floor. However, when I un-tick the 'Variant' option of the floor in 'Edit Type', then the geometry in the IFC seems ok, see image below.
But this is no use because the heights should not remain the same on various sections of the floor.
Are there any ways that I can export the floor element to IFC with the 'Variable' option ticked?
