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)

This happens when you try to access a set of tools that doesn't match the current template. By default, only the fills required for the appropriate tools for the styles are included in a map. Change that style setting to the appropriate style of your map, and you should see that the tools work fine.

If you want to use tools from another style, make a new map in that style, then in your current map, use draw -> insert file, pick your new blank map and hit ok. Once the map is on the cursor, ready to place, hit Esc. This will import the fills from that style into your current map.

1. Check the size of your effects. It is quite possible that the roads are on a sheet with a strong edge fade. If the edge fade is wider than half the road, it will disappear. You can check which sheet your roads are on using the Info -> List command. This is useful to make sure they are on the sheet you believe them to be on. Then check the effects for that sheet.
2. The trees have their groups set up for random selection from the group. I wrote a blog article about that last month, which you can find here:

3. Right click the :CD2STREET: button to access the options, where you can control this.

That shouldn't really happen unless there is something wrong with the MAP BORDER layer in your map (entities on this layer determine the extents on your map).

For the grid, the easiest workaround is to just click the "select points" button in the dialog instead of Apply, as this lets you manually set the location of the grid. Make sure Snap is on so you hit the lower left corner precisely.

You'll want to check the MAP BORDER layer for entities though, as wrong entities here may also act as an edge for drawing tools. Normally, this layer should only have a few lines that determine the edge of the map.

I am guessing the Quasimodo is a mistake in the guide, as that isn't the font used in the examples. My guess is that it was the first font Ralf tried, but then found worn Manuscript to be better.

Seems like an oversight that this font isn't included int he installer though. The easiest way to fix this is just to grab the Free Annual sampler. It includes the Jon Roberts style, including the missing font, among other stuff.
