We had a maintenance package up to st7. solid edge charged me $800 just for the priviledge of using the st7 license we already own, on a different computer. ( which in my opinion is a really shi*** business practice especially as we have already paid the maintenance fees but never upgraded at that time. )
we are transitioning to solidworks. but i still need access to the old assemblies and drawings so i can transfer them. i have tried updating older assembly files, and have encountered this mating problem. i was hoping it was something simple i have overlooked.
