:?: After drawing the architecture, how can I adjust the land elevations and building elevations in the three-dimensional model. How are we going to tailor things according to quota?
When you specify the floor heights from Settings/Floor general settings, the height of the drawing in the 3D window will be the same as it. You do not need to make any separate settings. After creating the plot with the 'Terrain' command, create areas such as pavements from the Terrain/Subzone command. Make the area where you want to sit the building with the Land/Land space command.
