Message comes up "exception has been thrown by the target of an invocation" when I try to open the file is there any way I can recover this file or has it been lost?

Help is much appreciated.

Hello, you might already have this sorted as this post is 2 months old. It is more than likely a fault in the drawing itself. Be quite thorough when you check through your work. It can be caused by one of the geometries that is used as a tool path. Check your parameters as well, hover over it with your mouse and see if it returns a value, I have had problems in the past where the parameters returned "NaN". Hope this helps!
