Hi guys, I got a similar problem : ############## import maya.OpenMaya as om sel = om.MSelectionList() sel.add( 'pCubeShape1.f[0]' ) dag = MDagPath() comp = MObject() sel.getDagPath( 0, dag, comp ) #########################
lines between ponds can get a MObject for pCubeShape1.f[0], 1.but if I run dagFn = om.MFnDagNode(MObject) if will have error like: RuntimeError: (kInvalidParameter): Object is incompatible with this method # is this because the MFnDagNode is for MObject handle pointing to a dag node instead of a component? 2. also,dose the components, such as poly face or poly edge has any bounding box? If it dosen't, I want to get all the points position on that poly face, and do some simple math, so how can get these positions? 3. After some conditions, I want to return the component MObject's string name,but dagPath.fullPathName() will return : # Result: |pCube1|pCubeShape1 # how can i get the original 'pCubeShape1.f[0]' instead? many thanks -ling On Nov 30, 9:40 pm, Paul Molodowitch <[email protected]> wrote: > Yeah.
