I made a optimization of a part in Inspire Solidthinking and exported this as a STL.
With Instep in transformed this in an STP file. But when i want to open this file solidworks always crashes. Is there a way to open this file in Solidworks and save it as a part?
Drag the STP file into SolidWorks DON'T open it from within the system.
When you drag, make sure to drag all the way into a work space- not just over the solidworks icon or in the start bar (works for some files, not this though)
