Hello dear all, Have a good day. I need a help from you as expert, that I want to model a Tube which shape will be somewhat curved. The Tube is a part of a motorcycle frame body. here the image is showing the 2D view of each side. Basically I want to use the weldments feature. The tube outside diameter is 22 mm. So I can not draw the 3D sketch for the path. please give me some suggestion from you.
