Hi all
I have a plane currently, have set its containers, Now i wanna get the point count of this object. So, i have to convert it into polygon object. I have read that the way to do that is by using the MCOMMAND_CURRENTSTATETOOBJECT. So i tried this way. My problem is, after i inserted the plane, I have to make it editable. So i have done this code:
BaseObject *ObjGrid = BaseObject::Alloc(Oplane);
BaseContainer *conGrid = ObjGrid->GetDataInstance();
conGrid->SetReal(PRIM_PLANE_SUBW, XNos);
conGrid->SetReal(PRIM_PLANE_SUBH, ZNos);
conGrid->SetReal(PRIM_PLANE_WIDTH, XWidth);conGrid->SetReal(PRIM_PLANE_HEIGHT, ZWidth);
doc->InsertObject(ObjGrid,NULL,NULL,TRUE);
doc->StartUndo();
doc->AddUndo(UNDO_NEW, ObjGrid);
ObjGrid->SetRot(Vector(Rot_H, Rot_P, Rot_B));
ModelingCommandData cd;
cd.flags = MODELINGCOMMANDFLAG_CREATEUNDO;
cd.doc = doc;
cd.bc = conGrid;
cd.op = ObjGrid;
cd.mode = MODIFY_ALL;
if (!SendModelingCommand(MCOMMAND_MAKEEDITABLE,cd)) return NULL;
EventAdd(EVENT_FORCEREDRAW);
ObjGrid = doc->SearchObject(vGridName);
How can I convert it into polygon object. Is that by using this following code:
Modelingcommanddata cd2;
cd2.doc=doc;
cd2.op = ObjGrid;
if(!Sendmodelingcommand(MCOMMAND_CURRENTSTATETOOBJECT, cd2)) return FALSE;
I have tried this but it gave memory leak problem. Anyone has any idea how to solve this?
Thanks for any help
Regards

Once you've used current state to object and have a pointer to the result, then just check that GetType()==Opoly and cast it using
PolygonObject* poly = static_cast<PolygonObject*>(obj).

if (!SendModelingCommand(MCOMMAND_CURRENTSTATETOOBJECT, md)) return FALSE;
PolygonObject *poly = static_cast<PolygonObject*>(md.result1);
But when i wanna get the active point from this object, seems like there is a problem with this following code, so that i could not
Activept = poly->GetPoint();
Activept[i].z = Activept[i].z - 3 + ZMove;
poly->SetPos(Activept[i]);
doc->InsertObject(poly,ObjToPolygon,NULL);
}
Can u plz tell me what's the problem of this?
Thanks and regards
