How to draw spiral tubes in Ansys Workbench
 

Hi, I am new to ansys workbench.

My geometry is spiral tube attached to a cylinder's inner curved wall. I first draw a 3D curve similar to sin curve. Then use a circle to sweep via this 3d curve. But my problem is my spiral tube did not have the same shape. I mean, some part of the spiral tube exceeds the cylinder wall. I use the same standards to draw points and then create 3D curve. Could you help me find out what's the problem?

Thank you very much!
