Beginners question: creating a Loft driven by spline.

jakob_strebel

Hello all,

I am trying to create a loft between two planes.

In the first plane I draw a triangle (the position is fixed to 0,0).

In the second plane I draw a circle (the position is fixed in X but not in Y).

Now I try to create a loft defined by the spline.

The Y-position of the circle should be positioned by the spline.

I cannot get to the root, which causes the error message.

Thank you 

Here is the drawing:

Was the triangle intended to be rotated a bit? The spline (intended as guide curve) should be coincident with the top of triangle and horizontally as long as the loft will be. You can then make the circle coincident with end of spline. Guide curves must be coincident with the profiles (typically end points). I broke up the circle to match the number of elements in triangle to make this demonstration easier. A loft can be made with un matched element count but that increases difficulty.
Hope this helps you get going.

@glen_dewsbury Thank you helping to understand where the root of the problem was. The triangle was not intended to be rotated.
