Wow. Thank you! I might try the Geometry way if this doesn’t work:
I created a mesh using a math function for sine wave, and converted the perimeter of the column mesh (post014) into a Curve. But the corners are off. A little advice here would be appreciated as well.

Creating plane mesh to parent the actual sine wave object. then adding modifiers to plane mesh.
Plane mesh instancing the sine wave object child.
