Oh boy you are quick :) Sorry I did post before I manage to to finish typing.

If you watch on about 1:25 after you have mesh your model you have the ability to reselect surfaces perhaps isocurves for remesh purposes . That would be great since you could constrain the polyflow this way (?)

Hi adam, the problem with stuff like that is that in order to do that requires adding quite a lot of UI mechanisms to control all that stuff - it greatly increases complexity of the UI.

That app that you are showing there is a really complex super expensive app that has the entire app 100% dedicated to mesh construction for advanced analysis work.

MoI is way more focused on having ease of use and a simple straightforward UI, and jamming in too many highly complex mechanisms can be a good way to ruin those kinds of qualities...

Point taken but I'm not asking for FEA capabilities just the abilyty to select couple isocurves so I the user decide the the poly direction.

Hi adam - actually meshing does already follow the isocurves of the surfaces being meshed.

The way meshing works is by first creating a quad mesh which is in the UV space of the surface - all the edges of those quads are on isocurves of each surface being meshed.

An isocurve has a particular meaning for a NURBS surface - it means a line of constant U or V in the surface's parameter space. Picking a line of some other orientation would no longer be an isocurve, isocurves are only either horizontal or vertical lines in UV space.
