Hi all,
Here is the new toy.

The last file is for french users only.

Enjoy

How about including the ability to use a layer as a mask for including/excluding selected areas for component placement? Or how about being able to select a material type to include/exclude? Thus, if I had a street layout on a layer, I could click on 'Streets' layer and use it as an exclude mask for vegetation. Or I could click on a 'Soils' layer and 'include' this for component placement. The material option would allow me to select a material named 'dirt' as receiving all vegetation components.
