I'm trying to add a piece of steel to a frame I created several days ago. As you can see in the pic, I had no trouble adding steel members and trimming them. This morning, an attempt to add one more cross beam on the sketch line to the right, generated this error message. I have attempted to place a member on several sketch lines in this assembly with the same results. Has anyone seen this "unknown" error?
Restarting Inventor was unsuccessful. I will try on a new assembly and see if I get the same results.
