(Maya) Smart Curve Extrude

Inspired by Blenders vertex extrude. I have hack together a way to replicate a similar functionality in Maya. 

This script is a Heavily Modified version of ShiftClickSmartDupe.mel script originally from Autodesk, to include the functionality for extrude Curve cvs.

v1.2 

• Support for maya 2025 added.
• Fixed issue with new curve creation when selection second cv point.

Important note: Smart curve extrude needs closestPointOnCurve.mll (plugin) to be loaded in order to work properly

No longer need to replace the original script from C:\Program Files\Autodesk\Maya2025\scripts\others

Simply just unzip the scripts and put it into user script directory C:\Users\User_PC\Documents\maya\20XX\scripts. 

Restart maya.

To Activate after starting Maya:

Simply select a Cv curve> go into Control Vertex mode> select cvs and hold shift + click drag> curve will be extruded. 

HotFix 1.1 -- fixed issue with starting point extrusion

Methods:

Single CV (start cv or end cv)

Shift + LeftClick Drag will extrude a new segment from selected cv.

Single CV (any cv between start and end)

Shift + LeftClick Drag will Create a new Curve starting from the original selection position.

Multiple CVs - End or Start of Curve

Shift + LeftClick Drag will extrude a new segment from the start for the Cv selection. 

Multiple CVs - Middle of Curve

Shift + LeftClick Drag will extrude 2 new segment from the start and end of Cv selection. 

All CVs

With all the cvs selected> Shift + LeftClick Drag will extrude a single side mesh.

CAVEAT: Current version doesn't support Bezier Curves.
