Keyframed Morphs of spiral surface

This is an extension to my original as it extends far beyond the original question

I want to apply a spiral surface deform that morphs between keyframes and am asking what would be the best way to do this in inventor.

It is an experiment in schroeder QRD (diffusion) and gas physics as applied to a hand drum.

There is a deforming ring which will rotate as it spirals up the length of the drum. During its travel, it will smoothly transition between deform/no deformed stat.

The end result will be similar to this but according to the keyframes

Can this be carried out in a single operation?
Is it better solved as a group of transitions then combined?

The guide

The deform ring applied for proof of concept

And these are the indicative keyframe positions

Thanks

Hi! I guess the same "twist" workflow can apply to the deform zones. However, I am not sure how you would blend the two deform zones. Loft might be the only choice but the geometry in this case may not look pretty.

Many thanks!

so the solution is, create a step file, export to Rhino and apply twist in about 25 seconds and finish the rest in there; using the inventor file as a dimension drive state file. Very disappointing unfortunately, for a program of this cost (inventor)

Engineering is functional art 🙂
