No, CA3 doesn't really care about the location, it just lives in the CC3+ folders wherever they might be.

Did you get the right version of the CA3 installer? There is one installer for CC3 and one for CC3+.

Nice. That last one is great.

Not by using the grid command, no. The "even columns are higher" option is just for hex grids due to the way hexes work, they have to alternate, but it is not a generic feature for offsetting grids.

It is too late for me to go into detailed explanations right now, but you should be able to do this by setting up a symbol fill. Symbol fills use repeating patterns, so you just need a fill style symbol (which is a regular symbol) that captures the minimum repeating pattern you will need, probably a 2x2 grid square pattern, but with the left column offset.

Give me a word if you can't figure this out by yourself and no one else replies with the instructions and I'll come back with more details when I have time and is awake.

Those looks great. But there doesn't seem to be a cat lounging on any of them??

The way to navigate them is with CC3+. All the maps have navigable hyperlinks that can be clicked to navigate the atlas.

It used to be a separate viewer back in the day, but it became redundant to keep it updated since CC3+ itself already offered all the functionality and more.

If the tools take too much space, you can always turn then off temporarily from :TOOLSICON:
