Configuration - Units

In this section, you can set the working mode with measurement units.

In CAD program to set units for topographical style means to change units from CAD program so that it will show decimal numbers accordingly to decimals allocated for coordinates, angles origin will be orientated to N and angles will be measured in topographical way (clockwise). This setting is made when TopoLT program is loaded.

In TopoLT program measurement units can be in metric or english measurement system. When you change measurement system some checks have to be done, these checks are described at What needs to be done when changing measurement units.

Decimal number for coordinates represents working precision. All coordinates will be approximated to this precision. Changing this value will influence the writing mode in coordinates’ files and in coordinates’ tables as well. This value will establish also the precision for fixing points when commands FixPct and AutoPct are applied. The values of calculated areas modify by increasing this value.

Decimals number for elevations is the decimals number with which points and contour levels elevations will be written.

Text with the name of measurement unit for coordinates will be used when the coordinates will be written in a table.

For distances, areas and volumes that needs to be posted when they are calculated you can choose decimals number, reduction factor to measurement unit and text with the name of measurement unit.

Determination of distances, areas and volumes will always be made in basic units, for metric system in m, m², m³ and for english system in feet, sq.ft., cu.ft. To transform these values from one unit to another use reduction factor. For example, to transform distances from m to km reduction factor is 0.001, and to transform areas from m² to ha factor is 0.0001.
