There are two snap modes you can use while drawing. Snap mode is set in the Map menu or using the drop down on the Overlay toolbar.

You can snap to the lines of the grid by selecting “Snap Edge” and snap to the center of the grid tiles by selecting “Snap Center.” Snap modes also affect item points, so if you can easily edit an existing item.


I want a road connecting my locations and I want it to go through the hex grid tiles so it’s easy to move characters along it. I change the snap mode to “Snap Center” and click on the tile I want the road to start in. When I move my cursor to my second town, the road snaps to the center of each grid along the way and the snap highlights each grid. I click to place the point and then click the tile with the ruins and then right click to finish the road.
