What I know is that to use these pattarns I must draw in layout. And then its very timefull. I must open plann in layout and then draw on top of it new plan ant then I can use patterns.... is that right???? maybe I do not know ..?
Then Snap. If I want to snap nice somewhere its a huge risk I will snap in wrong place. On big plann risk is mall, but on small furniture details ets... its big. When I place dimensions in SU, I can zoom wery close snap dimention then return back save csene with dimentions ( i usually make several scenes- one side view, one top..etc) Then I open these scenes and make Hybrid render.
I make all section cuts also in SU too. Maybe I can send you some SU file... you will see how I do these and maybe will help to fin better ways. But I work these way already 3 years... final result is nice.. but I wouuld like to do it right way of course
