Hi Michael,

thanks for your lights.

Would it be possible to have an interface something like for extrude and possibly even better one "set dir" for each curve for the worst case scenario where each curve is a line and the "extrude dir is not perpendicular!

As a general rule I would think it's preferable to have some kind of feedback like for the extrude command and the possibility for the user to make choices instead of nothing happening and not knowing why. Just my penny.

I'd like your advice also for other "potential glitch" if ever one come by again, do you which we report then to you, to the forum or by pm.

Thanks again,
Felix
