The Point Codes Manager is used to manage the point codes for a survey as well as creating and updating traverses based on those codes.
A Survey's Point Codes
In TPC, a survey keeps track of its own point codes in a .pct file with the same name as the survey. The Point Code Manager is where you work with those codes. When you save and open a survey, TPC saves and opens that surveys point codes.
You can set the Point Code Manager to display additional information about each code, like whether or not points are sorted within a traverse created by a code.
If you have lots of point codes and want a way to manage them more easily, you can group similar codes together, then collapse and expand individual point groups as needed.
