I am trying to add insulation to a pipe. I can go through all the steps to make it, apply it to pipe, see it shaded around my pipe. When I go back to my assembly view from the edit route option, my covering is not there. I read that you need to check a box for the covering to appear in the drawing, but I cannot find where this box I need to check is. If anyone can help with this, it would be greatly appreciated.
