Offset Interval Dialog

Compute offsets from each traverse point, within the range you select, to a straight line. Offsets can be added to the current traverse as side shots or placed in a separate traverse.

Offsets are not computed for side shots, benchmarks, etc. If you want offsets from these points, first change them to control points.

Specifying a Line

Specify two points that define the bearing/azimuth of the line or specify one point and type in a line bearing/azimuth. The points used to define the line do not have to be part of the traverse, only part of the survey. Refer to entering equations for more information.

Specifying a Range

You must specify the range of points within the traverse by selecting those points in the Traverse View.

Line Starting Point, Bearing

These define the line to offset to. Use the [>] pick button to select the point and bearing from the current drawing. There a separate [>] pick button that lets you select the line from the current drawing. The end of the line you click nearest to will be the Start point and the bearing will be computed to the other end of the line.

Points on Line

This group of options allows you to specify labels and descriptions for the computed points.

Starting Label

Specify a starting label or label mask. See Labeling COGO Points

Next Label

Increments the current starting label to the next available survey point label.

Description

Enter a description to copy to each created point.

Copy Offset Label to Description

Copy the description of the offset point to the point created from it.

Offset What

You can create offsets for the entire traverse or for just the currently selected points. You must select the points to offset before accessing the Right-of-Way Offset dialog.

Offset Option

Choose an offset direction. Perpendicular is the default. North/South and East/West are the other options.

Summary

View the offsets report on the screen, which shows the posting intervals, average offset and average interval. Summary does not create any points, it just displays a copy of the report that can be sent to your printer.

Save as Offsets

Compute the offsets and insert them as side shots in the current traverse. Offsets have the same point label as the point they were computed from but with the extension "-OFS".

As an example, the offset of point 101 would be 101-OFS.

Save as Traverse

Compute the offsets and save them to a separate traverse. The name of the new traverse will be the same as the current traverse but with the prefix "OFS-" added to the traverse name. The new traverse is inserted into the Traverses Manager immediately after the current traverse. The offset points themselves are labeled just like points inserted as side shots.

Close

Closes the Offset Interval dialog and returns you to the Traverse View.
