Opening
The Opening 
tool includes the following methods of creating vertical openings in floors and roofs:
|
Automatically by similar; |
|
Line by specifying two points; |
|
Arc by specifying three points; |
|
Arc by specifying start, center, end points; |
|
Circle by specifying a center point and radius. |
You can combine a few construction modes such as Line by specifying two points, Arc by specifying three points and Arc by the start, center and end points when creating a opening.
|
Please note that a opening won't be created correctly if its borders are crossed. Creation of opening out of floors and roofs is not correctly. |
Opening parameters:
