SAT / DWG export failure

[halam]

Hi,

 

 

I am having difficulties exporting these elements in release 2014.

What could be the cause of this? Mirroring behavior?

 

 

I need DWG SAT to do some (steel)work and rebar detailling in other programs AutoCAD, Allplan etc.

I did manage to get it out as mesh.

Turning it into a solid seems just as hard in AutoCAD..

(mesh will do for now..)

Command: convtomesh

MESHSMOOTH

Select objects to convert: Specify opposite corner: 15 found

Command: surfsculpt

Mesh conversion set to: Smooth and optimized.

Select surfaces or solids to sculpt into a solid: Specify opposite corner: 15 found

 

Modeling Operation Error:

Cellular Topology structure is corrupt. Is topology okay?.

 

 

(what does Cellular Topology really mean? )
