I have a part which fails to produce a contour flange. The sketch consists of an arc connected to a spline. Both the arc and the spline as individual elements produce a perfect contour flange but when I join them the coutour flange operation fails.
Sheet Metal: Contour Flange Creation failed.
Outer Strap.ipt: Errors occurred during update
The attempted operation did not produce a meaningful result. Try with different inputs.
Try decreasing bend radius
Feature Compute failed.
Could somebody please help with this. I am trying to model a wrist cuff.
I am using Inventor 2014.

Spline not tangent to arc.

The problem has to do with the way the spline interacted with the circle. Inventor wanted to make that a bend. Take a look at the modifications I made to your sketch. First, I made the start of the spline tangent to the circle. Then I opened up the profile of the spline a bit to move it away from the circle, to prevent any overlaps, which would also cause some errors.

Just remember: Inventor can't interpret your design intent. When you have non-tangent edges in a profile intended for a contour flange, Inventor will apply a fillet to those profile corners to create the bend. So far as I know - and I could be wrong, I haven't tested this exhaustively - you can't fillet the end of a spline.
