Extrude Path-Object

[Neokil]

Hello,

I am new to WPF and programmed a Pie-Chart.
Now i wonder if it's possible to extrude the Path-Objects to get a 3D-Model?
I'm aiming at something like that:

Now the question is, is it possible to simply extrude my 2D-Path Elements or do i have to go a completely different way? (If I have to it would be nice to have some catching phrases)

Greetings
