Hello dear community, I would to ask you how i do a flat map in the editor. I dont know. Thanks on All people they help me.
What do you mean with a flat map? The route's 2D map is created as soon as you create a route and the tracks ( and route markers, if you make a KML file ) will appear on the map once you put them on the tiles.
I think the OP wants to know how to start with flat terrain without having to import any SRTM/LIDAR/DEM stuff. Like in TSC where you create a new route, give the coordinates and reference template for the assets used, and are presented with autogenerated flat terrain you can instantly work on.
But that's exactly what happens when you do so and what BRD means: When you create a "route" project, there is a rectangle flat map, which you can use to create a fictional route if you want and place assets, tracks and other scenery elements on it. And that's before you apply any Lidar or SRTM on to that map. But maybe OP wants to expand that flat map? Looking forward to what OP really means.
