I have built a costom shape,and want to use it like normal shape in stencil. But I can't add it into stencil. How can I do?

Stencils draw different paths for the same Shape base class. The only other time you need a stencil is when using the palette. In that case you can just add your custom shape directly to the Palette.Shapes collection.

Let me know if this doesnt answer your question,

Hi James,

I have done what you told me,but new problem appears. When I drag my custom shape from palette to model, it Create a "Shape" object in it not my Custom Shape. Because I have add a mouse double click handler for MyShape,and pass this message from model mousedoubleclick to it. But In the mousedoubleclick handler of model,I get an error of "can't conver shape to myShape". My code is:

dim myShape as MyShape

myshape = selElements.Item(0)   ' this cause error msg because of can't convert

myshape.onDoubleClick(e)

Thanks for your Help!

When you drag a shape from the palette, a new shape is created using the Clone method. You need to override Clone in your subclass to return a new MyShape eg

public override object Clone()
{
    return new MyShape(this);
}
