Hi there. As someone who works mainly from blueprints, and has done so for many years, you should try to keep the entire project in Moi.

I made you a video because it's easier to watch the process than me try to explain it here.

And after how many control points are use for make a curve who have a direction changement ?

(even here seems arc circles)

Thanks. I'll take a look.

That doesn't really address my point. The raison d'etre of my approach is that I can enter constraints directly from the blueprint one for one.

Thanks for the video twofoot! I've been using MoI for a long time and never realized the Align function was there. What a time saver!
