Computing Offset Intervals for Posting Line

 

 

 

 

This routine can be referred to as Offset Interval or True Line Offset.

 

True Line Offsets (6:05) - Compute offsets from a random line to a true East-West line

For PLSS examples, see  Cadastral Learning Guide.

This is the COGO routine you will use to post a line. It computes the offsets of points to a line defined by a point and a direction. It's like the Offset to Alignment COGO routine for just a single tangent.

•Choose COGO | Offset Interval to display the Offset Interval dialog.  See Accessing COGO.

•Select What data you want to computed offsets for.

•Enter the Starting Point and Bearing to define the straight line you want to offset to. You can use equations to get the direction from existing points or pick the data from the current drawing.

•Choose the options you want and enter a First Label for the computed points to use.

•Chose Compute


Save Offsets as Side Shots (option)

TPC computes the offset points and saves each one as a side shot from the original points. The side shot points have the same point label as the original point, but there is an 'OFS' added on.


Create a New Traverse (option)

TPC computes the offset points and saves them to their own traverse. The new traverse name starts with 'Offset Interval:', followed by the original traverse name.


Printing the Offset Report

•Choose Summary to append the offset data to the current Report View.

To adjust the column widths of this report, choose Tools, Program Settings, Widths from the TPC Desktop. Enter the Label, Angle, Distance and Description widths you want. TPC uses these widths in a number of reports.
