Practice Map for Testing

General Discussion
1

Do test maps exist where if one wants to merely practice placing buildings and producing units on a map (without having to take the time make minerals), and without an opponent?

I just want to test placing buildings on certain maps for placement and strategy purposes.

Again, does this type of map/mod exist on SC2?
Thanks!

Go to Custom -> melee(or something starting with m)
Maps take a short while to load.

Then:
Select ladder maps(it is a dropdown button above the map list.

Select the map and wait for the lobby to load.

Choose the options you need (No AI) and start the game.
