The traverse defines the sequence of courses or calls and the style determines the wording and formatting to use. The legal description is then written to the appropriate report, like the Legal Description Report or Traverse Report where it can be reviewed, edited, printed and saved.
Because you have complete control over the points in a traverse and can edit the legal description styles, you have complete control over how TPC writes your legal descriptions.
Along with a few simple rules like whether or not to include sideshots and point descriptions, traverses create a natural link to legal descriptions.
Commencement Point Chain
TPC calls the sequence of points that define the Point of Commencement to the Point of Beginning the Commencement Point Chain (CPC). TPC determines this from the sequence of control points in the traverse, but you can also specify your own CPC in the Traverse Properties Commencement dialog.
