D-Tools basically integrates all the little things you do. Wire numbers (labels & reports), parts & products for your proposal, system design, prints and schematics and a bunch of other stuff i am missing.

So when your dragging in a wire.. lets say the speaker cable in the Dining Room.. DIN-008 is generated automatically and when you print your wire labels its there. DIN-008 is on the wire report.. its connected to everything.

If your doing things manually. Your dragging in a wire.. giving it the number you choose. Now you have to manually create a spreadsheet to go with it. So 1 spread sheet like the example i gave EBG above with the wire numbers. If you stick to simple numbers vs room names you can use the number spread sheet over and over.

And one spread sheet thats a Wire Report telling you what each wire is. I put together this screenshot to try to keep with our Dining Room theme :). Obviously you can have as much or as little detail as you want. You could include wire colors, a notes column that says things like "in cabinet" or "behind bed". A column that says what its for like "Phone" "Keypad". A column that says "Local Loop" or "Home Run".. whatever you want.
