After importing terrain none of it could be found. The file contains 4 Kb. Thanks for any advise.

Turn on the tags for the Location Snapshot and Location Terrain. Then Zoom in to the axes. You have something located at a huge distance from the origin so Zoom Extents will make the terrain show very small.
Notice what happens when I choose Zoom Extents. The teraain is shown selected way over on the left.
Here I’ve cleaned up your model and purged unused stuff from it. About 64% file size reduction.

thanks, I must have inadvertently used an incorrect tool.
