How do you draw a spline perpendicular from a surface?
I have asked this question before and I am still not sure how to do it.
I have two surfaces at any angle. I want to be able to draw a spline that starts perpendicular from one surface and ends perpendicular to the second. How would you do this?
My solution has been to draw a short straight line segment from each of the surfaces and then span the line ends with the spline. I also have not figured out how to make the spline then be tangent to the short line segments. Any help with that question, would be great also.
Thanks,
P

Alright, This is really helpful. I think we should call this topic finished. I'll try my hand at a simple script this week and show it off in a new formum topic, no matter how simple.
Thanks, guys.

My thought was to use Cplane>Surface to set cplanes to the surfaces inside the Curve command and use these to set the curve points with Ctrl (Elevator mode). However, this falls down because while CPlane >Surface works fine for the first surface, the surface is not then deselected, making it impossible to set a plane on the second surface. That seems like a bug...

This approach seems to work for me under build 5.1.30129.1756. Using cplane inside the curve command makes the cplane coplanar with the second surface even though the first surface remains selected, so you can still use elevator mode to draw a segment that's perpendicular to the second surface. BTW, changing the cplane in the middle of another command is nifty, and not something I'd have tried without your suggestion.
