http://www.zwsoft.com/forum/viewthread.php?tid=884 Ever need to check to see how well VX is doing for STEP or IGES exports. 'T'aint easy finding something free to look at them. Round tripping doesn't answer the questions so here is a neat little solution. I have just tried out some new free viewers that seem to do the job fine. http://igsviewer.com/ http://stpviewer.com/ http://stlfileviewer.com/ there are a few other options for STL but for completeness. Price is right for the quick look. Disclaimer; These non VX items are presented by way of useful checking for VX users. I have NO relationship of any kind with the developers of these product. Aint nothing in it for me - pity. Cheers mudcrab 2010-08-12 20:17:30 http://www.zwsoft.com/forum/viewthread.php?tid=884&pid=4879 Thank you Paul, these could be very helpful.
