Loft command help

zdenek.hajn — Tue, 08 Feb 2022 10:03:40 GMT

Hi, i have 3 airfoils in 3 planes. I would like to loft them together, but I get errors... Can I make it this way, or I need to make it without loft. Yellow field looks like I would like to have new body...

Thanks for helping.

I can check your file at a later time.

The yellow body, is preview, and it is announcing that the volume is in some way effected by a self intersection.

you may find that you need exactly the same number of spline points in each profile.

You may find you need a number of Rails.

If the airfoil profiles are exactly the same, then you can change to Sweep command. Sweep with Path and Guide rail/surface.

Might help....

If you use a surface loft instead of a solid loft, it works fine.

@jeff_strater maybe there's some room to improve the solid loft behavior.

I get the same result with surface loft... Yellow lines and errors...

I see. The behavior of the lot tool could definitely use a bit of help here.

By pure coincidence I got it right on my first try, by selecting the curves, not the sketch profiles created by those curves.
