Non co-planar 3d union and extrusion

[nicolas]

Hi,

 

I'm looking for an autocad techniques to do the following things in 3d:

 

1. way(s) to union two non co-planar faces

 

2. way(s) to offset region

 

3. way(s) to extrude the unified non-co-planar faces

 

4. extruding a region with a closed path

 

Thank you in advance.

 

Regards,

 

Nicolas.

1. I just union'd 3 surfaces with different z values and different angles, worked fine. It created a kind of block with a grip at the middle of the mass.

2. Appears you can't offset a Region. Just have to copy.

3. Extrudes objects all in the same direction.

4. Not sure what a closed path Region is.
