Tell me about it, I got to work and started to wave link a part from one CAD file to another only to have after 45 minutes of sitting and watching the Customer come in with a CD with all new data. The data is different enough that the surfacing work I've done for the past 2 weeks is pretty much crap, I can use maybe 60% of the past work. That added to the fact I'm still trying to finish translating one of the files from CatiaV5 to NX3 after nearly 2 hours has told me that for a Friday today sucks. I need a vacation , if only I didn't have to wait until January for my new 3 weeks to start. Oh well gues i work on other boring things.
