Hi everybody,
Do anyone had this issue before, makeThreePointCircularArc nodes radius
attirbute is not updating...
Try this:
import pymel.core as pm
threePCA = pm.createNode('makeThreePointCircularArc')
loc1 = pm.spaceLocator()
loc2 = pm.spaceLocator()
loc3 = pm.spaceLocator()
loc4 = pm.spaceLocator()
loc1.setAttr('t',(0,0,0))
loc2.setAttr('t',(0,1,0))
loc3.setAttr('t',(1,1,0))
loc1.attr('t') >> threePCA.attr('point1')
loc2.attr('t') >> threePCA.attr('point2')
loc3.attr('t') >> threePCA.attr('point3')
threePCA.attr('radius') >> loc4.attr('ty')
curveShape = pm.createNode('nurbsCurve')
threePCA.attr('outputCurve') >> curveShape.attr('create')
this will create 4 locators, 1 makeThreePointCircularArc node (weird
naming), and one nurbsCurve node and an automatically created transform node
for the curve shape. Three of the locators will create the arc, the forth
one is to check if the radius is updating. It should move up as the three
other locators move. But it doesn't, until you force the plug update by:
pm.dgdirty( threePCA )
is this a bug about the makeThreePointCircularArc node, and do anybody has a
workaround... I'm working under Maya 2011 x64 Linux by the way
thanks
