About this Guide

Organization

The sections of this guide are organized to follow, more or less, the typical workflow of the design engineer.

  • New Projects
  • Modeling
  • Results
  • Advanced Topics and Supporting Information

Conventions

This documentation uses a few special symbols and conventions.

  • Specific text you are to type in are shown in bold.
  • Menu selections are separated by a "greater than" symbol. File > Open means, select the Open command from the File menu.
  • Buttons that are to be pressed, such as the OK button commonly found in Windows applications, are indicated with square brackets. For example "[Cancel]" refers to the Cancel button.
  • Tips provide useful information to improve your results. Notes provide clarifying information. Notes and Tips have a shaded background

TIP: This is a tip. Now that you know what they look like, use the tips to become an expert user.

NOTE: This is a note. Pay attention, this is important information.

Common Input Parameters

Station, offset, bearing, and angle are common input parameters used throughout the user interface. These parameters can be input with simple decimal values or in common engineering format.

Notation

The following notation is used to describe the common engineering format.

SymbolDescriptionExample
|Choose between pipe separated itemsL|R
Choose "L" or "R"
[]Items within square brackets are optional[+|-]
Use "+" or "-" or omit
xLowercase letters are digits 0-9dd mm ss.ss
Angular measure as degree-minute-decimal seconds

Stations

Stations represent a position along an alignment. Stations can be input as a decimal number or as a number of full plus fractional chains.

Offsets

Offsets represent a perpendicular distance measured from a reference line. Left and right orientation is based on the observer looking in the positive direction of the reference line. If the reference line is an alignment, left and right are based on the observer looking ahead on station.

FormatExamples
[+|-]dddd.dd
Values greater than zero are to the right of the reference line.

Angles

Angles represent a departure from a reference line.

FormatExamples
[+|-]dddd.dd
Clockwise angles are positive.
