I have come across something I have never seen before. I had completed a drawing with it being fully dimensioned and was ready to turn in for approval just when I noticed a missing Line on my drawing, Somehow using the ADD/HIDE line feature the line came back. Then now, My entire border of the drawing itself is not surrounded by a Purple square.

Purple? I have never had a shade of purple ever on my drawing before. But with further investigation, I have noticed that clicking on the drawing part, a yellow box has appeared around it too. So that tells me there is something wrong with my assembly itself isnt that right?

But even so, I'm not sure if the Purple square will affect my drawing in any way.

Has anyone encountered this before?
