I’m not familiar with that software as I use AutoCAD for all my building drawings. But if I need to create an object I draw out the components in plan layout and and convert them to mass objects. This is where you dictate the height or thickness of the components. Then “assemble” the components to form the whole piece. Then I’ll convert the whole assembled piece to a 3D block. It’s not that detailed and rather blocky but it does the trick. It sounds like a lot of work but it’s actually really fast and easy. It’s basically making blocks of different sizes and stacking them up in the correct order and placement.
