Lofting between splines

Anonymous — Wed, 14 Nov 2018 19:42:02 GMT

Hi,

I was wondering if this was possible. I have three sketches, with a spline in all of them. I would like to create a body in the space between them. A sort of cone shape.

Can this be done with some fancy lofting? I have not been successful so far.

Yep, when you fix the vertical sketch to become shaded like the low one,

select each as a profile, and the single connected curve as the rail.

(Front half of a wingtip uses that exact set up)

Might help...

It looks as if your taller, rear shape isn't being recognized as a profile (it's not shaded in tan). Let me guess, you drew the bottom shape first, and then when you drew the rear shape, you didn't make a new line across the edge of the corner, right? So if you turn off the visibility of the lower side, you will see that the rear side is open at the bottom. Just a guess.

Yes, the missing connection was the problem. I had to shell the body afterwards; that had its own unique challenges as well.

It worked out great - thank you all for the fast responses.

Just in case Shell give you trouble...you can approximate the desired result with another Loft instead.
