The posts in talkgraphics have helped tremendously as I am using Xara to develop a map. I usually find the answer to my question already here.

However, I'm stumped on this one. I would like to create a grid with lines (city streets) and then be able to use the lines to create the individual city blocks as separate objects. So, in a sense, I would like to create objects from the 'negative space' between my lines. (I want to create individual fills for the blocks, etc.) I don't want to just draw rectangles in the places for the blocks, as I'd like the option to change street widths, etc. easily, and then repeat the appropriate process for creating the blocks as objects.

Is it possible to make objects out of the spaces within a grid of lines?

Thank you!
