I need some help.
I think I have pressed something I normally do not press, what it is I don't know. However when drawing a part, assemble parts, making a flow simulation the part is surrounded by a grey box, and I can't seem to make it dissapear. It is really annoying.
I have tried to use the "glasses" Icon but it didn't help.
I have enclosed a picture that shows what I'm struggling with. the part inside the box is a tube that I have drawn.
I hope somebody can help me
