Parametric splines in SE

Parametric splines in SE

Parametric splines in SE

(OP)
Hi all,

I need some help on the following problem:
For a part with free form design, I would like to create parametric splines. This is, the splines are connected to points (e.g. ends of lines) that are constrained by dimensions. If I change those dimensions, the positions of the points are changed accordingly. I want the spline to follow these alterations in order to achieve a "parametric" spline. The problem is, as soon as I place a spline on the (parametric) points, I can no longer alter the dimensions of the points and end up with an error message from SE.

Any helps on this topic would be greatly appreciated!

Cheers,
Daniel

RE: Parametric splines in SE

For this I use the command Point in Sketch, and after I use the command curve for points in construction toolbars.

The command point are in Sketch->View->Toolbar->Change or modify toolbar.

Try the Curve by Excel table.  You can enter a list of keypoints to generate a 3d curve.

RE: Parametric splines in SE

I have only done a handfull of splines and I would always use a protrusion.  I would like to know why you are trying to do the points method you described.  What are the advantages to this, or the dissadvantages to using the protrusion.
