Catenary Curve Plugin for Vectorworks®

This plugin creates a parametrized catenary curve between two points.

It is essentially a "line object" plugin to get the initial couple of points on the XY plane.
Customizable parameters:

• Independent Z for both ends
• Direction [downward (chain) or upward(arch)]
• By length or by sag methods: you can establish the length of the chain or the chain lowest (or highest) point.

Also it is possible to extract a 3D polygon or a 2D polygon out of the PIO, with the provided buttons.
