INSTALL: place the .py file in your default script folder
LAUNCH SCRIPT (python): import gf_curveOnMeshCtx as cmCtx reload(cmCtx)
USAGE: /Select one or more meshes, setup the parameters and hit 'run' Shift + drag (up & down) : increase/decrease the radius Ctrl + drag (up & down) : increase/decrease the taper attribute
Draw Mesh : extrudes a mesh along the created curve Radius : base radius for the mesh profile Base Drag Mult. : precision when shift + drag Taper : tip radius multiplier (drives the scale attribute of the extrude node) Taper Drag Mult. : precision when ctrl + drag Add Current to Object list : includes the current mesh to the objects you draw on. Step : minimum distance between 2 adjacents CVs
