3D spline control

Hello,

Is there any way to do BOTH of the following with a 3D spline

1. Enforce spline length (I know this can be done)

2. Enforce a minimum bend radius/curvature (I can't do this with a 3D spline?)

I know I can show the minimum radius but I want to enforce it so that it won't be smaller than a given value. Think rubber tubing and crimping.

If this can't be done then it should be... other CAD packages can.

Thanks.
