We have a part like this, and want to show the sinusoidal profile in a 2D drawing - to give more details.



Essentially, we want to unwrap the edge/curve - anyone have any ideas?

I know you can form a curve onto a surface, just wonder whether you can do the opposite?



Cheers

Seems like that would just be a matter of projecting it onto a plane and then repeating it.
 
You might creating a thin cut and using a spinal bend to unwrap it. Make the length of the spinal bend curve equal to the circumference.



If you don't mind showing a graph or something on your drawing, try creating a User-Defined Analysis feature that measures the distance of a point to a plane around the circumference.

You can unwrap surfaces using Tweak Flatten Quilt... try making a surface using the curve and then unwrapping it.



I was fooling around with flattened quilts a couple of months ago for a user here. If your quilt forms a closed loop, you'll need to trim it before you can flatten it. You can use a curve to trim it, but remember to save both sides of the trim.



See attached zip file for an example:
