In the NET Engineering options you have access to the color table.
All colors that can be assigned to the ducts as the first or second color are managed in the color table.
By default, these color values are predefined:
If you want to define a new color value, this can simply be done in the last line. As soon as a value has been entered there, a new, empty line is inserted.
The color table can be exported to Excel, adjusted there and then imported into the same or another project. Make sure that no new columns are added or the column names are changed. The color value RGB_VALUE must be valid in Map 3D.
