I have Solidworks 2011/2012/2013 & 2014 installed on a Dell M6700 laptop running a NVidia Quadro K3000M graphics card and I have a serious problem with the draft analysis feature. When I use draft analysis, it will only work once and then nothing shows up again. Sometimes, if I have been working on an assembly, I can't use it at all. This applies to all Solidworks versions. I have searched everywhere for an answer to this irritating problem but no luck. And the draft analysis features is important to what I do so it's really causing me problems now. Has anyone experienced this before and can anywhere share what they did/do to get around this?
