Hey
I have a small project that will need too many layers.
I have a layer for every month and every month have 6 categories (every category have a diffrent color).
Every year have 12 layers and 72 categories.
I want to be able to turn off not just layers but the "categories" too
 

For example.
I want to only see  layers for this month and only blue dots (category) visble the reset I dont want to see. The reset of the layers turned off and junes other categories turnd off too.
 
 
I have tried with 72 layers (june green, june blue etc) but after a couple of years I will have over 500 layers.

Have you looked into the use of Layer Filters?What type of project is this?Is AutoCAD necessarily the best software for the project?John Connor2011-06-30 17:12:00
