Explode non uniformly scaled block (3DSolids)
While searching for a solution to my current problem I found in >>this<< post:
"AutoCAD will not explode non uniformly scaled blocks that contain Regions, Surfaces and/or 3dSolids."
Is this still the current behavior of AutoCAD? Or is in the meantime any possibility (or found someone a workaround) to explode a non uniformly scaled blockreference which contains 3DSolids.
Example: Given is a block definition including a 3DSolid box a x b x c. After inserting the blockreference non uniformly scaled I see a "box" a' x b' x c'. (How) can I get a 3DSolid with the dimensions a' x b' x c' ?

Without a feature for scaling geometry non-uniformly, other than blocks, I cannot think of an automatic procedure.
You could make a copy of the block and explode it down until you only have lines. Create a block out of the lines and scale it non-uniformly. Explode that block and use the lines as reference to build your new solid.
Another option is to import the dwg file into 3ds Max. Once in 3ds Max export it as a dwg file. Back in AutoCAD insert the dwg file and explode it which will yield mesh objects. These can be converted to a solid with surfsculpt!

Thanks for your confirming answer (which I feared). Even if it is not what I had hoped. ![]()
Have a nice day.

It is often nearly the same as competely create a new solid from scratch. But in some cases this way can really be helpful.
I appreciate the workaround using 3ds Max (even if I don't have it). This is what I had buried untraceable deep in my mind (beginning Alzheimer?
). Thanks too.

If the box shape is a realistic example, and an unequally-scaled Block of the 3D Solid by itself, and orthogonally oriented, you don't need to redefine the Block with Lines and non-uniformly scale that and Explode it, or export anything, etc. You can quickly "trace over" an unequally-scaled 3D-Solid box with ENDpoint object snaps in a [very aptly-named] BOX command. However, if the box is part of a larger Block with other components that you want to remain their unequally-scaled selves after Exploding, then you would need to [temporarily?] redefine that Block so that the box in it is made of something like Lines, so that the containing Block can be Exploded.

No, it isn't. Is was only an example to describe what I want to get - a non uniformly scaled solid (complex geometry). To scale any geometry non uiniformly I know only the way create block, insert with different scale factors, explode the block This works well with a lot of geometr - but unfortunaztely not with 3DSolid.
