I'm brand new to SW2007 and have hit my first brick wall.

I have created a fairly large weldment (287 cut list so far) and want to do a test to see where the weak points are in COSMOS.

Here is the eDrawing (SW2007) for the structure: http://www.launchcomplexmodels.com/P...unts_Part.EPRT


I start COSMOSXpress and everything initially seems good until I go to select the Material (Alloy 2014 is what I'm trying to use for now). The computer sits there number-crunching for five-minutes and then all but one of my structural members totally disappear from the graphic area leaving me with only the sketch layout!

I'm sure its just me 'being a newbie' and that I've just missed 'something' simple, but I can't seem to work out what I did wrong. Can anyone offer any advice?

Thanks
