An "offset" tool?

[marosell]

I'm using Xara Photo & Graphic Designer 6 and I'm having fun with it. But there's one functionality I can't seem to find that I really need. I'm a CAD operator (and have that mentality), and I really want my AutoCAD Offset tool. It allows you to copy a line or shape a certain distance away. More importantly, if you "offset" a shape inside or outside it's boundary, it automatically makes the new shape equidistant from all the borders.

Here's a picture of what I'm trying to do.

Anyway to do it in Xara P&GD6?
