I am using the Modeling Library to add some points, then delete the original points.
What I am looking for is this....
Here is the code I am using:
BaseDocument *doc = mdat.doc;
BaseObject *op = doc->GetActiveObject();
BaseContainer *bc = mdat.bc;
PolygonObject *objPoly = (PolygonObject * )op;
if(!objPoly) return FALSE;
if (!mod || !mod->InitObject(objPoly)) return FALSE;
LONG pointCount = objPoly->GetPointCount();
LONG polyCount = objPoly->GetPolygonCount();
CPolygon * polys = objPoly->GetPolygonW();
LONG * points = new LONG;
Real width = bc->GetReal(CHAMFER_WIDTH);
n.Init(pointCount, polys, polyCount, NULL);
PolyInfo *pli = n.GetPolyInfo(0);
if (!pli) return FALSE;
LONG pointA = 0, pointB = 0;
//Iterate Through Edges
for ( int i=0; i < polyCount; i++)
pli = n.GetPolyInfo(i);
for (int side = 0; side < 4; side++) // test all 4 sides of a polygon
// only proceed if edge has not already been processed
// and edge really exists (for triangles side 2 from c..d does not exist as c==d)
if (pli->mark[side] || (side==2 && (polys->c == polys->d))) continue;
case 0: pointA = polys[i].a; pointB = polys[i].b; break;
case 1: pointA = polys[i].b; pointB = polys[i].c; break;
case 2: pointA = polys[i].c; pointB = polys[i].d; break;
case 3: pointA = polys[i].d; pointB = polys[i].a; break;
mod->SplitEdge(objPoly, pointB, pointA, width);
mod->SplitEdge(objPoly, pointA, pointB, width);
//Delete Original Points
for (int i=0; i < pointCount; i++)
//mod->SetNgonFlags(objPoly, i, MODELING_SETNGON_FLAG_NGONQUADS);
if (!mod->Commit(objPoly, MODELING_COMMIT_NONE, NULL)) return FALSE;
When I compile this code and run the plugin in C4D this is what I get...
From what I can tell, the points are being placed correctly but the ngons are not being created correctly. How do I build the ngons based on the new points that exist? It looks to me that some ngons are being created but because the indices are all over the place, it is not creating them correctly.
Anyone have a solution for how to build the ngons correctly?

You can't just delete these points. You have first to connect the newly created points.
Just try it for yourself. Comment out mod- >DeletePoint(objPoly, i) and run your code. Then in Cinema delete the points manually. You will get the same messed up result. If you display the Ngon lines you will see why.
