I am trying to draw a custom 2-d shape on the screen and then create its 3-d model using Away 3-d. I have included the classes that I have used. I am yet to create the 3-d model using extrusion.
The problem is that there is always a small offset when making the drawing. When trying out the code please click on the screen at two different points to get the drawing start and going. The drawing is triggered on MouseDown. Please do help me as I have been trying to find a solution for quiet sometime.

This question would be more appropriate on the Away3d forum at http://groups.google.com/group/away3d-dev
