This has come a long way! Fantastic work!
Major thing is how good it all looks, the grey Icons are pleasant to the eyes very connected to sketchup yet less graphical intensive, They do look great!
The thing is, I started by looking at the left menu wich looks very good with a clever grouping of tools and moved on to the right menu, wich also looks very good yet a bit hard to read wich menu is wich.
It starts with entity info and as it needs something selected to work so I selected a group from an old model. As I tried the nice looking buttons I checked visibility off!
I can’t turn it on again!
There’s no outliner, there’s no turning on visible geometry. I searched for edit styles and I couldn’t… I lost my model
Glad I found something that simple!
