Well, yes - the Live Components are still in “Labs”. We know it’s not quite finished, but wanted to get some feedback on it. Live components are still under development.
Materials are treated as any other parameter, so authors/designers must specify them. If you can’t find one you like, or it is not an option, you can bring the component into SketchUp, Right click > ‘Detach definition’ and assign materials the old fashioned SketchUp way.
As for sizing, it has been a little tricky for to find the best way of describing some things - I think most of our doors use the size of the door itself, and any frames are derived from that. That being said, I take your point about the opening. We are aware of this issue and have some ideas about it, but it is a little way off. In the mean time, I will pass this info onto our content team.
And also thanks for the note around consistency - I’ll also pass that back to our content team.
