in the attached files I am attempting to morph the objects on the flat rectangular surface to the non planar surface. Rigid is OK. I Believe I have everything set correctly but the objects stay where they originate and do not morph to the new surface.

What am I doing wrong?

TIA

You should supply “P0” and “P1” inputs which represent U&V parameters of base & target surfaces…

Maybe this is also a little different from what you expected …

Yes… VERY different than what I was looking for. I have saved that GH and may find use for it in the future. I need the shapes to morph to the target and retain their relative scale and spacing. This distributes them with their original size and relative position. Very interesting but not what I need here.

Still looking for how the Sporph should work.

Thanks for the input,  
Robb

So what you want is to transform the original geometries anyway and different from what you said “Rigid is OK”.  
If it doesn’t matter, use “Surface Morph” instead.  
And the U & V domain of your target surface is not uniform. In this case, rebuilding your target surface will also help.
