Hi to all and tanks for your appreciations.
@crackwood01
Now I understudy what you propose.Thanks for enlightening me!
You've right but, in SH3D, we have 2 different things:
-1. The elevation which are measured from the bottom of piece;
-2. The high of piece;
We need both.
I think that could be solved by Daniels118 trough them 3D Dimension plugin to make it to be able to measure objects even outside the wall or building.
At that moment we could improve some options in this plugins.
Anyway we will try to do something in this way.
Will be useful to many other users.
