Hi guys, i have a problem with getAttr/connectAttr the cvīs from a curveOnSurface.
I only get the "local coordinates" (uv-coordinates from the nurbsPlane), or the "world coordinates" from a "duplicated curve" ... but i didnīt duplicate the curve.
--> i have no idea whatīs going on and how to solve the problem.
I think i need something like the cvPosCmd.mll but i donīt have it and iīm not able to compile it for maya 8.5.
please help, thanks lois
//// just for example:
nurbsPlane -p 0 0 0 -ax 0 0 1 -w 10 -lr 1 -d 3 -u 5 -v 5 -ch 1; objectMoveCommand;

connectAttr -f ($arclenInfo + ".controlPoints[0]") ($cube[0] + ".translate");
//// --> when i want to connect ...controlPoints[1] [2] [3] etc. it connects to the cvīs from a "duplicatCurve"
