Spline through # of points
Spline through # of points
(OP)
Hello all. I am looking for a way to create a 3-d splines (representing a cable, tube, etc.) that will go through an arbitrary number of points and be tangent to line segments at each end. I would like the points to be created in a way I can use BMX techniques to ultimately fix the locations of the points in space. Any suggestions? Thanks in advance!
Best regards,
Matthew Ian Loew

"Wildfires are dangerous, hard to control, and economically catastrophic."
"Fixed in the next release" should replace "Product First" as the PTC slogan.

Thanks but I would like to restrict the tools usage to what can be found with a foundation license and no special training.

The points themselves can be created in 3D space as an array offset from a Coordinate system. (The Csys itself should probably be located at the vertex of one of the line segments).
If the points exist as an array, it should let you create the UDF simply by selecting the point array and the two line segments to which the tangency must be maintained. (this should allow you to choose an arbitraty number of points as you require).
I haven't put this to the test yet, but that would be the first thing I would try.
Hope it works

I've created a curve when I was creating an SGI logo using this method.
I think you can do this with the foundation license and Datum Curve feature.
