So I made this heat sink, and everything worked fine for about a week, i used it in several drawings. I used it in another file for flow analysis and out of nowhere it stops working, I did not make any changes to it.

I tried making the fins using a sketch and linear sketch pattern in a brand new file, but it said there were too many sketch relations and crashed that way. i dont know why it wouldnt work the way i did it, i basically made one "fin" in the center, and did linear feature patterns in both directions; but i am new to sw and i could be over looking something simple.

Anyway, it would probably be easier to see the file than for me to describe it.

any help is greatly appreciated.

thanks,
