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
