Instruction Manual

Horiz. Dist: is the horizontal distance from the reference point to the new point.
Vert. Dist: is the vertical distance from the reference point to the new point.
Store point: When this is checked, the computed point will be stored with the name specified here.
[Solve]: will compute the location for, and optionally store the new point.
Intersection
[Cogo] [Intersection]
The Intersection
screen computes, and optionally stores, the coordinates for the intersection of two lines, where the
lines are tangent to existing points. Each line is independently defined by a known direction or a known length.
Point 1: is an existing point that is tangent to the first line.
Point 2: is an existing point that is tangent to the second line.
[Distance] / [Azm or Brg]: is the length or direction of the specific line tangent to the specified point.
Store I-Sect 1/2: These items are only available after solving the screen. Once solved, the computed intersections can
be viewed from the Map
card where you can decide which intersecting point(s) to store in the Input card.
[Store]: Stores the intersecting points checked above, which were computed after solving.
[Solve]: will compute the intersecting point(s) and open the Results
card.
Offset Line
[Cogo] [Offset Line]
The Offset Line
screen is used to store points or an alignment that is parallel to an existing set of points, a polyline, or
an alignment, at a specified perpendicular offset.
Note: When storing points, the number of new points stored will equal the number of points in the selected polyline or
point range. If the offset is from an alignment, the number of points stored will equal the number of nodes that occur in
the horizontal portion of the alignment.
[Tap Line…]: allows you to tap an existing polyline or alignment that the offset will be computed from.
[To/From…]: allows you to enter a range of points that define the line where the offset will be computed from.
Offset: defines the offset distance and which side the offset occurs. The right or left side is referenced from the first
point that defines the specified line.
Save to job as an alignment: when checked, the computed offset line will be saved as a new alignment under the
name specified in the Description field.
Note: Spiral curves cannot be generated in a new offset alignment. If the original centerline contains any spiral curves,
