Hey everyone. I have been looking around and trying to figure this out. I am guessing that I need to use the Modeling class for this. Can someone point me toward how to add a point to the edge of an existing polygon object? for example, I would like to iterate through all points and add a point a certain distance away from each point. Would I use SetEdgePoint()? If not what would I use?

Thanks.

If it causes the polygon to go beyond a quadrilateral then you will need to look at the Ngon routines because you can't have a CPolygon with more than 4 vertices (a,b,c,d). It will need to be an Ngon otherwise.

Please have a look at the edgecuttool.cpp example, specifically the Modeling::SplitEdge and Modeling::SetEdgePoint methods.

Btw. the Modeling library takes care of the Ngon stuff, so no need to worry about that.

cheers,

okay so I am trying to cut an edge using the edgecuttool.cpp example..

Am I doing this right?

  
  
 Real width = data.GetReal(MY_WIDTH);  
  
Modeling * mod = Modeling::Alloc();  
if (!mod->InitObject(op)) return FALSE;  
      for (int i=0; i < lngPolygonCount; i++)  
      {  
  
  
          mod->SplitEdge(op, i, oldPoint, width);   
  
          oldPoint = i;  
  
      }

I am not getting any splitting at all happening on my cube. Anyone know if I am leaving something important out?

Okay here's an update.. I'm sifting through the SDK and trying to match what it says to do...

  
  
if(vpPoint)  
          {  
              AutoAlloc<Modeling> mod;  
              if (!mod || !mod->InitObject(op)) return FALSE;  
  
              LONG my1, my2;  
              Real width = data.GetReal(CHAMFER_WIDTH);  
  
              for (int i=0; i < lngPolygonCount; i++)  
              {  
                  my1 = i;  
                  my2 = i-1;  
  
                  mod->SplitEdge(op, my1, my2, width);   
  
                  oldPoint = i;  
                  if (!mod->Commit()) return FALSE;  
  
              }  
          }

still no dice.. trying to put this in the mouse input method of a tool plugin
