This command can be used to topology elements (nodes, sections) with different colors according to specific condition.
To create new thematic map configuration, click on Theme mappings – Sections/Nodes – New.
Select the data that will represent the condition from the upper right part of the dialog:
Thematic mapping of sections changes the color of line that represents section.
Thematic mapping of nodes draws circle around node in appropriate color.
Thematic mapping of polygons shows a colored hatch over each polygon.
Thematic mapping can created in two ways if selected condition (data) is number (e.g. terrain height).
Selecting option "Specific", each specific value will be colored with one color (e.g. one pipe diameter – one color).
With option "Continuous", it is necessary to define number of limits by which mapping will be done or size of limits.
They have to be typed in appropriate fields. Beside field "Size" there is data about minimum and maximum value of selected key.
Colors that represent each value of the key can be set in two ways.
By selecting option "Automatic" program will automatically define certain color for each value of the data. User can define number of colors that will be used for thematic mapping. When this option is turned off user can define specific color for each value of the key. Colors can be changed in drop down list by selecting appropriate color. Drop down list is opened when user selects color for certain condition in the table.
