I was working within a model already on file. I made numerous change to the original model (and didn't save= first mistake). I then imported a hinge file that contained two parts. I place both parts in the model seperately. I then constrained them to one piece within the original model. I then created a piece of sheet metal. I tried to manipulate the sheet metal with a flange, and it would not allow me to select an edge. I then tried to constrain the imported hinge part to the new sheet metal, and it would not allow me to select the hinge part. I thought it might be a glitch, so I saved, closed out, and reopened the file. (second mistake.) It was after I reopened the file that I noticed that it now says (For Drawing) after the file name. Because I saved and reopened the file, I cannot back up to where this is not the case. How do I get back to being able to manipulate the model? Please help! I'm on a deadline.
