How can I delete an editable poly 's face?

[354926089]

I have found two faces in an editable poly whose vertices are all coincident and would like to delete one of them.

#include "PolyOperation.h"
using namespace PolyOperation;

bool DeleteOverlapping(PolyObject* polyObj)

{

MNMesh& mnMesh = polyObj->GetMesh();

int numVerts = mnMesh.numv;

int numFaces = mnMesh.numf;

int iDeleted = 0;

for (int i = 0; i < numFaces; i++) 

{

MNFace& face1 = mnMesh.f[i];

for (int j = i + 1; j < numFaces; j++) 

{

MNFace& face2 = mnMesh.f[j];

if (IsFacesOverlap(face1, face2, mnMesh)) 

{

// delete it. Prompt "PolyOperation" when compiling: is not a class or namespace name

PolyOperation::DeleteFace(polyObj, j);

numFaces--;

j--;

iDeleted++;

}

}

}

return (iDelete == 0 ? false : true);

}
