This rhinoscript is not needed for Rhino 5. Pipe now works on multiple curves.
This rhinoscript is a basic multipipe command. It allows the user to select multiple curves, the start radius, the end radius, and the cap type. The script then differentiates closed from open curves and runs the appropriate version of the command. This script is basic because it does not yet allow the ability to add thickness to the pipe which can create a conflict with the standard pipe command if it has been run prior with a specified thickness.
