better way to make blend curves than fixing target curves?

[cekuhnen]

I often do not want when making a blend curve that the primary cuvres / target will get changed because their

tangent handles get activated

I noticed in your video, you didn't set the "Comb Scale" of curvature comb. If you want to check if 2 curves are G2 continuity, please select the curvature combs and set them to same "Comb Scale" value

thanks

the comb scale function is broken and when scaling too much will scale the combs of the elements differently giving you the impression continuity is broken.

when doing the surface edge comb all works as expected!
