Thank you Nikki,
I will try to use tc for modeling additional objects, please see attached pics, the bar was done in tc and imported as rhino, will try with IFC later, I've got pro plat 2018, in my opinion tc is much better in modelling. Archicad solo and octan rendering engine saves me lots of time on paperwork, takeoff for qs etc. Rendering don't require so much time. TC DWG export isn't working properly, every time I want to send my drawings to other companies there is something wrong. Also bimx viewer with vr can become very good marketing point. I'm designing, doing the specs, building regs and program, then managing whole project. It's handy to have all easy accessible.
