how can model a coil tube with prolongation like in the picture??
you don't need a 3D sketch, you can use the edges of the construction geometry as the path. I wrapped the path onto a cylinder, swept the "tube" without merging, delete the cylinder body, and then circular pattern the body.
I would make construction base geometry to drive a 3d sketch that would drive my sweep.
its so difficult to drive 3d sketch smoth and clear because it will effect the sweep geometry in the tube bend place ....how can i do it correct and clear???
When you get your 3D sketch RMB one end and select chain then go to tools spline tools and use fit spline.
Why delete the body? Why not keep the body hidden so if you decide to change the Ø, then you can.
deleting the body does not in any way interfere with changing the diameter later. that image is from an assembly with 3 configurations of the part in it. the diameter of the construction cylinder is different in each config, as is the instance count on the circular pattern.
