Hello everyone,

I have a solid as shown in the picture. I want to draw a 3D sketch (eg, like a sine/cosine-wave) on the highlighted surface based on its equation. I tried using Spline on surface but do not achieve what exactly I need. If I use the equation driven curve option I am unable to place it on the surface since I do not know the equation for the surface/curves. Can someone give me some pointers on how I can proceed on this problem?

Thank You!

Hi Chidam

This is quite an involved process but may work

I used the edges of the unknown curve to create a sheetmetal body with a loft, I added some flats to one end so it can be unfolded, the equation curve was sketch on this flat face, I made a cut then refolded and converted into a 3d sketch
