Creating a polygon along route with various widths

[MatejTacer]

Hi,
I have a route layer which represents roads with two attributes describing width, on both sides of each route.
Now, I would like to create polygons representing surface areas. How can I create a polygon (a kind of buffer) with different offsets on each side?
Thank you for your suggestions.

Has really nobody had that kind of issue, or my question wasn't clear enough?
Basically, I need to crate a buffer of linear objects with different widths on each side...
Any ideas? Thanx.

It is much easier than I had anticipated. 🙂
For some reason, I had overlooked the "Side Type" parameter at Buffer tool. When you realize that, the rest is a three step process:
1. Create buffer on one side
2. Create buffer on the other side
3. Combine the two

Check out the code.
