Hi,  while I was constructing my part, I think I may have accidentally pressed "convert entities" and now my whole part including all the construction lines are converted. I didn't notice this until I was complete with my part. Is there a way to "de-convert entities"?  I'd like it to go back to the sketch and only convert the parts I want to convert.  Can anyone please help?  I would hate to have to resketch this part.  I guess I can go back into the drawing and delete every single construction line but thats going to be a pain. Thanks in advance!
