Re: Multiple Parts saved as One STL file

The old Imageware Surfacer product, now IDEAS Freeform, does a good job
of separating out individual stl files.If you have access to that you
can split them out and them boolean the individual stl files to make
one. Or just let it double scan. Won't hurt too much.

Hi guys,

I have a STL file of an assembly that was created in SDRC I-DEAS.

The person who did all the design work on it, while still in I-DEAS,
all the individual parts into one supposedly solid piece. Then he
that merged piece out as an STL file and is asking me to make a model
of it
for him.

The problem is that when I go and look at the preview of the laser
scans for
each layer, I can clearly see that it is still taking each individual
of the original assembly and treating it as if it were a separate

Anywhere two of the elements overlap . .. the Sinterstation is
going to scan those areas twice (or three times if there are three
occupying the same space)

I had the same problem with some architectural models that were sent to
one time . .and the architect was able unify or merge all the parts in
different way so they became one completely solid piece.

He was working in some AutoDesk product or another though, so he
help with IDEAS.

Anyone have any sort of clue how to handle this?

I'd hate to have to resort to exporting everything out in IGES (or
other format) and then importing it again and finally saving it as an

Any help would be greatly appreciated.
