Can PIDDLE plot 3D geometry?  such as a set of x, y, z points?
This is to plot a 3D fan blade by a set of sections.   Each section is
specified by a set of x, y coordinates and a z coordinate.
Ideally, there will be a coordinate at the origin, the points can be
connected by straight lines or even splines, and one can rotate, pan
and zoom the display.
If Pidlle can not do this, is there another package that can?
Thank you in advance
