Introduction:
This Script/Plug-in allows one to draw surface on a surface by specifying a sequence of points.
Steps:
- Use “ConvertToBeziers” Changes the structure of the surface to a Bzier surface.<important>
- Load the script.
- Input Degree of U & Degree of V, and then u can select ‘y’ to change the point’s weight.
- specify those points, done.
Note:
Dragging *.rvb file onto the Rhino window will load and run the script.
Certainly u can add a button and run the script.

Update:
The plugin has revised and brought up to date, but it can be temperamental, u must save ur work first. On this version, u can edit the surface by those defining points.

It seems I’m not able to use this plug (v.4)
After following the explained workflow I don’t know “where” place the points on the base surface, even if I use the “near” osnap.
A little video could help.
Thanks
