If I were doing this I would first make sure the source maps covered an identical area by trimming them together in an image editor (PS, Affinity Photo, GIMP - take your pick). Then I would turn on the snap grid and import them one after the other, using the same snap points to define their extent. Once they are in CC3 you can scale them together, so keeping the alignment you've already set up.

There are probably many other ways you can do it. This is just the way I would do it.

Check that the layer it's on isn't frozen.

Have you tried stacking the cliff symbols?

One of our viewers asked if it was possible to align the field fills with the fields. Yes it is. Some styles have field drawing tools that do this automatically - styles like the Ferraris Style and Darklands City.

1. If you have a polygon of field you want to align, right click the Polygon tool and pick "Shaded Polygon (Angle by Edge)" from the menu.
2. Click the side of the field you want the fill to be aligned with, and right click when finished.
3. Type EDITSHADING and hit ENTER, then check the box called "Shade Only Copy". That will remove the roof shading applied in the moment you used Shaded Polygon (Angle by Edge).

The three stages look like this, where field number 2 shows the roof shading automatically applied by Shaded Polygon (Angle by Edge).

If you want to edit your field use Explode just once to return it to it's former state.

Interestingly, this poll is going in quite a different direction to the similar one on the FB Group page.

I would say there are probably a higher proportion of lurkers looking for handy maps to use on the FB page, though, and not so many actual CC3+ mappers.
