Hello, David!
I DEEPLY appreciate ypou for your help!
1. You are completely right!! Your first solution fron previous post is the best!!
I did the Interference and Body Modifiers a hundred of times, but I completely forgot about SUBTRACTING mode... : ((
This IS the solution!
2. I tried to Add a Body Modifier (in "Cut Openings" mode!!) (I like BM much more than Interferences) for the "mising part" of the Wall over the foundation slab and FAIL!
The situation is completely the same - we can't move the Door to the corner!..
3. Then I tried to add an Interference for the this "mising part" - and with NO luck!
The Walls even don't make a Cleanup - and WORSE - I can't even see (in Model) that part of the Wall!
In Plan it isn't combined with the Wall and have not its Plan Hatch...
So your first decision is the best:
- intersect the Walls;
and
- do the "Interference" -> "Subtract mode" with adding the Mass Element for removig the overlapping part of the foundation slab!
THANK YOU VERY MUCH again!
The question for Moderators: can you correct the Theme of my post ("doRR") - for best finding it in future by thousands an thousands of grateful people?..
