Importing .dwg/.step/.stl files in 3D

using essentials v.4.1.2 trying to import known 3D .dwg file and have it retain dimension once imported, but come out 2D after using these import settings, am I using incorrect settings or is there something im missing in order to retain third dimension?

Importing any 3d file does not require special options to be selected. Can you share the file?
