Hi Michael,

Thanks for all of that info & the work around.

When creating the Base Surface, I'm just wondering if currently there's a "preferred way" of making it?
So for example is it preferable to use a Base Surface made from Sweep more than a Loft or Extrude surface??
I already know that each of those commands produces a slightly different surface when you've turned the Points On....
...so just wondering if this has any bearing on those UV directions too??

OK, so that selection arrangement for use within the next Beta is similar to how the process currently works within Rhino4 now.

Thanks for the heads up on the End Caps too.
I'll be sure to remove any of the Caps on those items prior to doing the Flow.

Are you talking about the base surface here, or the target surface?

For the base surface pretty much the easiest thing is one of the plane drawing tools under Draw solid > Plane.

For the target surface it really depends on what kind of shape you want, since those various tools make different kinds of shapes so it's not like you can always swap one for the other. But yes, as far as UV layout goes it is possible for different construction methods to put the UVs in different directions, I'm not sure of the details about that for each one right now. In the next beta it won't really make a difference though anyway.

Some commands may benefit from doing a Rebuild on some of the curves before constructing with them when you know you want to use them for Flow - that's because the result of Rebuild is evenly parameterized. So if you see something like a flow on to a 1 rail sweep is kind of stretching or compressing somewhat in various zones, try doing a Rebuild on the rail before doing the sweep - that can result in a sweep that works better for a flow target.

Hi Michael,

Thanks again for all of that info, & yes, I was only referring to the Base Surface.

Thanks for Flow and the ShrinkTrimmedSrf explanation, it was frustrating how my little globe test failed at first.
Now it works!

It's funny how, even though Flow has only been out for a few feeks, I've already naturally used it about 5 times where it would have been really difficult without it.

Such a handy feature :)
