Transform along a path

Hi everyone.

I’m looking for an extension that will allow me to transform a shape along a path. For example, if I had a square and a circle linked by a line; is there a tool that will allow one shape to transform into the other, following the line between the two?

Thanks for your help!

You might start with Fredo6’s Curviloft from Sketchcation

That’s exactly what I was looking for. Thanks Dave!
