Hi,
    I am presently working in the area of tolerance analysis. I would like to purhcase a software
to work in this area. I had an oppurtunity to check out three softwares which are 3DCS, CE/TOl and VSA.
   If anyone has worked with these softwares, please do recommend me which one would be apt for doing
analysis on welded assemblies. Your advice would be greatly appreciated.

Thank You
