Spring with lines and arcs


New member
How to make a spring whose top view looks like two parallel lines joined by arcs (tangent-tangent)?

you can create a rectangular extruded hollow surface with rounded edges, then create a helical surface around the rectangular surface. Extract the curve from the intersection of the two surfaces and use a sweep to create your spring.

Another way to do it is to form a curve on an extruded rectangular surface using pythagores theorem.

If you need some help with the second method just let me know.

Thank you very much, Jules and proed. I am very clear with the first method. The mentioned site is also very useful.

Jules, I'd like to know about the second method also.
