This dialog gives you finer control over how the traverses and drawing interact.
Each traverse has its own Traverse Settings that determine how the traverse is drawn. Most of the time, this is the way you want it. But what if you want to draw a traverse with a solid line in one drawing and show it as an adjoining boundary with a dashed line in another drawing. In TPC, you would use Unique Traverse Settings for one of the drawings.
Control Poitns, Lot Labels, Sideshots - turn these options on to get the unique settings you want. Turn them off to return to the traverse settings stored with the traverse.
If you find that you want to use these unique settings in other drawings, you have a couple of options.
Choose this option to copy the unique settings (for this traverse in just this drawing) to the traverse itself. The traverse will now appear this way (with these settings) in any other drawing in which it does not already have unique traverse settings.
Make this traverse unique or not unique in all drawings in the survey. If you have created unique traverse settings for a traverse then realized that you are probably going to want unique settings for traverse in every drawing, choose this option. You can now make changes to the traverse settings of this traverse in any drawing without affecting the way it looks in the other drawings. That's because each drawing would have its own, unique settings for this traverse.
When you turn this option on, TPC uses the distance type of the traverse to label lines and areas.
By default (when this option is turned off), the Distance type specified in the Drawing Settings, Miscellaneous dialog determines the factor used to label all survey lines and compute all areas in the drawing. This option lets you override that setting for just this traverse.
You should not have to use this option routinely. It has the potential to mix different distance types in the same drawing - something we don't generally do.
