The following script gets you the world position from a random uv-coordinate of the selected object. I affraid I don't know what you mean with symmetry line.
import maya.OpenMaya as om import maya.cmds as cmds import random def GetDagPath(nodeName): sel = om.MSelectionList() om.MGlobal.getSelectionListByName(nodeName, sel) dp = om.MDagPath() sel.getDagPath(0,dp) return dp def UvCoordToWorld(U, V, mesh): mfnMesh = om.MFnMesh(GetDagPath(mesh)) numFaces = mfnMesh.numPolygons() WSpoint = om.MPoint(0.0,0.0,0.0) util2 = om.MScriptUtil() util2.createFromList ((U, V),2) float2ParamUV = util2.asFloat2Ptr() for i in range(numFaces): try: mfnMesh.getPointAtUV(i,WSpoint, float2ParamUV, om.MSpace.kWorld) break; #point is in poly except: continue #point not found! return WSpoint f = UvCoordToWorld (random.random(), random.random(), cmds.ls(sl=True,type='shape')) print [f[0], f[1], f[2]] -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
