Solid Directly from Splines?

[Wittenborn]

I am using the "Through Curves" tool to create a surface between 10 spline (airfoil) sections that define a propeller blade. The end result is a surface. I WANT a solid.

I have found that if I put an elipse at each end, and then use the elipses as the start and end section, with the spline in the middle, I get a solid.

Am I getting a surface from the splines because they are in fact splines? Is there a way to loft between splines and get a solid directly, without having to stitch (sew) the surfaces together?

Are all the splines in each section planar? If not, it could lead to the problem you describe.

Here's another idea: can you extrude some simple shape (rectangle for example) then trim it with your resulting swept sheet?

cowski,
That is what I ended up doing. Tech support suggested that I sweep the surface in two halves, then stitch (sew) the halves together. I found that intersecting a solid rectangle with the skinned surfaces worked pretty well.

Thanks for the info.
