KB10298 - Using the DK Scale property.
Use of the Scale property requires defining a Coordinate System for the project and a Coordinate System for the subject layer.
Then, for example:
GIS.Scale := 1; // means 1 meter on the screen is one meter on the map
GIS.Scale := 1/1000000; //means map in scale of 1:1000000
