Hi there,
i've got a problem here. I'm trying to extrude all polygons of a PolygonObject:

  
     //Select all  
     ModelingCommandData cd1;  
     cd1.doc = GetActiveDocument();  
     cd1.op = pObj;  
     cd1.mode = MODIFY_POLYGONSELECTION;  
     if (!SendModelingCommand(MCOMMAND_SELECTALL, cd1)) GePrint("could not select all");  
  
     //Extrude  
     BaseContainer bc;  
     bc.SetReal(MDATA_EXTRUDE_OFFSET, 2.0);  
  
     ModelingCommandData cd;  
     cd.doc = GetActiveDocument();  
     cd.op = pObj;  
     cd.bc = &bc;  
  
     if (!SendModelingCommand(ID_MODELING_EXTRUDE_TOOL, cd)) GePrint("could not extrude");

am i missing something? the SendModelingCommand() for extrude returns false, but if i replace MDATA_EXTRUDE_OFFSET with MDATA_EXTRUDEINNER_OFFSET and ID_MODELING_EXTRUDE_TOOL with ID_MODELING_EXTRUDE_INNER_TOOL an inner extrude is done.
do i have to do something special for extrude (whereas inner extrude is workin with the "same" code)

thanks in advance,

affa

got it:
cd.mode = MODIFY_POLYGONSELECTION;
is needed... but why isn't this needed for an inner extrude? anyway... it's working

greetings,
