Hi everyone,

We are in the middle of R&D period of a project and searching for 2D graphical components and evaluating Nevron Diagram for this purpose. Wee need to interactively draw a kind of room with 4 or more walls like Floor Plan sample. But this has to be done interactively by a custom tool. We tried to override NCreatePolygonTool but could not. Below is the skeleton of the overrides but we need to know the underlying execution and semantic.

Could you please give us a clue to draw 2 polygons interactively at the same time with this tool, which one of the polygons will cover the other? I mean the base NCreatePolygonTool creates a regular polygon, but wee need an inner polygon whicl will mimic as the inside part of a room.

It was hard to tell but i hope it is clear :-)

Best regards

public WallCreateTool(): base()
{
base.Name = "WallCreateTool";

protected override INDiagramElement CreateElement(bool preview)
{
//NDiagramElementFactory factory = View.ElementFactory;
//var inner = factory.CreatePolygon(preview);
//var outer = factory.CreatePolygon(preview);
//return inner;

return base.CreateElement(preview);
