Hi there,
I recently stumbled upon the following problem:
I exported a SolidWorks-file as Parasolid, compressed it at normal rate with
WinRar (ZIP). The part consisted of some freeform geometry and a bore with
a plain diameter of 20 mm.
Our customer unpacked the part with WinZip, opened the part in SolidWorks.
No changes in geometry or shape can be measured up to this point. Then he
exports the part as STLwith fine quality settings for rapid prototyping. Now
the STL file shows some differeces in geometry. The scale and especially the
bore diameter is not round but somehow oval and the meassure is stretched to
20,5 mm!!!
When I send the exactly same Parasolid not compressed, the part also opens
correctly in SolidWorks at our customers. He then exports with the exactly
same STL export options as before and the STL part is generated correctly as
it should be.
??? This behavior is reproducable but a reasonable explanation is still
lacking.
So what could be the conclusions for this weired behavior? Could WinRar or
WinZip have caused the screwed STLs?
I hope I was able to describe my problem. Any opinion on this subject is
very much aprechiated.
Thanx & regards from Germany
