Hi egoldid1,

I tried out the function deleteFace() and it seems to work for me. May I get a a sample of the problem that you're having?

thanks! but, i should tell you, deleteFace, work in python api, but it dont work in c++ api for me.

this is my c++ code:

MObject oThis = thisMObject(); 

MDataHandle origMeshSrcHandle = data.inputValue(inMeshAttr); 
MObject inMesh = origMeshSrcHandle.asMesh(); 
//inMesh: 
MFnMesh inMesh_fn(inMesh, &stat); 

MFnMeshData meshDataFn; 
MObject outMeshObj = meshDataFn.create(); 
MFnMesh outMeshFn; 
outMeshFn.copy(inMesh, outMeshObj); 

outMeshFn.deleteFace(12); 

MPlug oMPlug(oThis, outMeshAttr); 
oMPlug.selectAncestorLogicalIndex(0, outsAttr); 
oMPlug.setMObject(outMeshObj);

Hi egoldid1,

In order to delete the face of the copied mesh, you must first create another function set to operate on it.

outMeshFn.copy(inMesh, outMeshObj); 
MFnMesh newMeshFn(outMeshObj);
newMeshFn.deleteFace(12);

If you prefer, you can also operate on the input mesh object before copying.

Sorry for my late reply, but I hope this helps!
