Recreating a topo drawing in 3d

It’s not hard to learn how to create a mesh out of level lines, you can do it with the sandbox tool or with a plugin like toposhaper, the way they work is very similar, just select all the lines and click on the tool, it will generate automatically a mesh with the shape of the terrain, if you have the lines on a same plane, you must select all of them but one, then move the lines 1ft deselect the next and repeat until you have all the lines separated 1ft on the Z axis. It’s not hard at all.
