I seem to be having trouble with the interface for creating tubes.
I want to create a tube with an OD of 6.1 mm, and a wall thickness of .6 mm.
So I go to Solid/Tube and choose the base for the tube. I check Solid. I then type 6.1 which gives me the required OD. The next screen shows “Diameter” and “Wall Thickness”. I don’t get the point of this screen. “Diameter” in this case seems to be the Inside Diameter of the tube. However, if you enter an ID for a tube, you don’t need to specify a wall thickness, and if you enter a wall thickness, you should not need to specify an ID.
My preferred way of working is to enter only the wall thickness. However when I do that, I end up with a tube of which the ID is in fact the wall thickness I entered, and the wall thickness is therefore much thicker. It is wrong every time. So to do it correctly, I now have to calculate the ID for the tube I want to create, and enter that. the Wall Thickness field is left blank.
What am I doing wrong? How do I create a tube by specifying the OD and the wall thickness, and NOT the ID?
