Calculation a profile by using the active (or last) measurement line.
If this checkbox is selected, profiles will be calculated from all the models in use. The result will be one profile. Otherwise, only active surface model is used.
If this checkbox is selected, a new profile window will be opened and the profile is added to the element list of that window. Otherwise the new profile file is added to the element list of the main window. Profiles have to be in main window’s element list, if they are to be used in road construction.
