Hi Michael,

I tried the 2 pass approach using curve instead of surfaces and though I had to figure out how to do it, it was a bit tricky , I managed to create the button the way I wanted and position it on the target surface.

This idea of creating a kind of 2.5D object (basically a flat object (2D) with a little thickness) bending (flow) it in 1 or 2 of direction and kind of applying it where I want is an operation I would use quite often in my work.

In the joined file you'll see in front row the setup I've created, from left to right, the button, the base lines, the target curves and surface and "crossair" where the final flowed button will be positioned.

The second row shows the setup for the first flow, you'll noticed that I rotated (top view) the button in the center of the target curve.

The third row shows the setup for the second flow, you'll noticed I've rotated the button 90 degree in front view before using flow.

The fourth row shows the button rotated back to its proper orientation.

The fifth row shows the button properly "oriented" on the target surface.

I suppose all this can be automated in the future and I hope I'm not the only one that would use such a series of operations. Maybe you have already something in mind to facilitate this kind of 2 curves bending.

Even if this specific application never happens I believe it's much easier to do then having to create the button in place directly on the surface. Imagine a much more complex shape like something out of Zsurf for example.

This flow command is simply awsome, I'm sure many user will find many use for it. Excellent work!

Thanks,
Felix
