I've been using solidworks (2005) for a while, and have gotten sorta decent with it. I started to toy around with building things using extruded material, like from 80/20 and bosch - but I'm feeling like I'm wasting alot of time managing a boat load of configs... I have a part, say a basic 30x30mm t-slot extrustion, and then I'll have a few configs - where 1 length is 30" and another 20".. Perhaps 1 config has a 12" piece with 45* chamfer ends. I have hte base stock, and then a drawing where I perform the cut.... In the sketch I set my dimension, and store that dimension in whichever config I want. But the problem with this, is as I build my model, if I decide to resize something a little bit, I have to go back to the part and modify the configuration.. This just seems very time consuming. Of course, it's not always just length - like I said, some pieces might have 1 or 2 beveled ends, at various angles. Help get pointed in the right direction. Thanks
