Ryan Feeley Nov 1, 2016 6:26 PM (in response to Ryan Feeley)Here's another workaround (no fully tested) that is still ugly. Use two sketches to force the solver order. First create arc in a 2d or 3d sketch on the desired plane. Now midpoint extrude a surface with the arc. Create a new sketch with the style spline and the "On Plane" relation. Add the "Equal Curvature" relation to the arc. This will be overdefined since a tangent relation is automatically applied, and one component of the tangent direction is redundant with the "On Plane" relation. Now delete the autogenerated tangency relation and add it back as tangent to the extruded surface, rather than the sketched arc.
I realize that the math is messy when you have "On Plane" relations in 3D sketches, but I want that relation on the style spline itself (rather than say all the control points) so that I can readily change the degree.
