This map is now in the atlas. Congratulations to Quenten on his 100th atlas map.

Drawing tools select the sheet automatically to help you place things on the right sheet.

In this case, the easiest here is to just use Change Properties on it after drawing to just move it. Or, you can use the basic tools in the right hand menu instead, these don't have any smart functionality. Just manually set the fill style, and then use the Box or Polygon tool.

For scaling, I prefer non-visual scale for scenarios like this.

First measure the size of a hex in the image using Info-distance. Try to find points to make this as precise as possible. This is the source size. For my example here, let us assume this is 0.8

Now, measure the the distance on the CC3+ hex grid. Make sure to measure it in the same way, for example between two corners of the hexes. This is the destination size. For my example here, let us assume this is 1.93

Now, just right click :CC2SCALE:, select non-visual scale, set the origin point to somewhere. When the command line asks for the scale, simply type in source size/destination size, i.e 0.8/1.93 straight on the command line, no need to manually calculate it, and then hit enter.

You can move it with non-visual move much the same way. Just figure out how much it needs to move, and then give the distance as @distx,disty. The @-sign here refers to relative cooridnates instead of absolute ones. (Although in this case, perhaps it might be eaasier to just move them to an absolute position)
