Spline through # of points

[mloew]

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

Pro/Piping and Pro/Cable have those optins when defining the tube or cable.

"Fixed in the next release" should replace "Product First" as the PTC slogan.

Ben,

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

Do you know the X Y & Z values for these points? What I've done in the past is create a sketch with a spline we any number of points. Then edit the spline and read in a *.pts file that has true X Y & Z points. The only drawback with this is I haven't tested in three planes my data has only been X & Y points so I don't know if it will work. But you can give it a go.

Perhaps a User Defined Feature would allow you to create this.

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

Not sure if this is part of the foundation package or what (but I have it).

In WildFire 2.0:
Insert
Advanced
Pipe

When you do a curve through points it asks you for a single Radius or Multiple radius or Spline. If all the radii in the curve you wavt should be equal then you can create the curve with the proper tangency at the end by making a point between the end point and the end of the line you want it to be tangent to.

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.
