Rail misses the profile

[jrychter]

I can't produce a loft, because I get "Rail misses the profile" message for my rails. But, these rails do not miss the profile. The endpoints of the arcs have coincident constraints with a projection of both top and bottom loft profiles.

This looks like a bug, but perhaps I'm missing something?

Hi,

Rail 1 is connected to the magenta projection, but not to the profiles.
Disconnect the existing connection and create new ones to profiles 1 and 2 with Project /Intersect as shown in the screencast

thanks, @g-andresen - your solution is correct.  For @jrychter - the problem that you ran into is in your description:  "The endpoints of the arcs have coincident constraints with a projection of both top and bottom loft profiles" (bolding is mine).  Instead of using Sketch->Project, you should have used Sketch->Intersect, as Guenther does in his screencast.

Hmm. So I tried doing just that, but I'm running into another problem: it seems it isn't possible to intersect projected geometry. The top shape in the design is currently projected from the bottom one, since it is supposed to be the same.

Hi,

the points of intersection must snap to the two profiles as shown in the screencast

Yes, I understood that, I just had a problem in that Fusion would not let me intersect a sketch which was itself a projection. But it seems it's one of those things that quitting and restarting Fusion fixed (sigh). So, I managed to create my rails.

Thank you very much for your help, Guenther!
