Description

Import Points

Imports horizontal geometry points from an ASCII file via a text wizard.

Create Regression Line

  • Regression Line from Points - Takes a set of points and puts them into a proper order creating a linestring (regression line).
  • Regression Line from Line - Creates regression line from a 3D linestring.
  • Regression Line from Rails - Creates horizontal centerline geometry from selected left and right rail alignments.
  • Rail Line from Points - Creates a Regression Line from Rail Points for use in Regression Line from Rails.
  • Add Points to Regression Line - Adds horizontal Regression Points to an existing Regression Line.

Curvature Diagram

  • Horizontal Curvature Diagram - This tool displays a diagram representing curvature along the path of regression points in a horizontal alignment.
  • Vertical Curvature Diagram - This tool displays a diagram representing curvature along the path of regression points in a vertical alignment.

Horizontal Regression

  • Single Horizontal Regression - Creates a single horizontal geometry element that is a "best fit" to a set of regression points.
  • Quick Horizontal Regression - Makes an initial best guess of all elements (line, circular arc and transition spirals).
  • Calculate Horizontal Slew - Displays a graph that represents the horizontal offset between regression points and the horizontal alignment or regressed element.
  • Reset Slew Values - Resets/removes existing slew values to 0.00 for recalculation. Resets slew graphic representation.

Create Profile

Vertical Regression

  • Single Vertical Regression - Creates a single vertical geometry element that is a "best fit" to a set of regression points.
  • Quick Vertical Regression - Makes an initial best guess of all elements (line, arcs).
  • Calculate Vertical Slew - Displays lifts and lowers between a profile element and profile regression line.

Geometry Tools

  • Complex by Element - Used to construct a complex element of previously placed elements.
  • Define Profile By Best Fit - Used to construct a profile complex defined by best fitting through a selected profile.
  • Open Profile Model - Used to generate a View that presents a desired feature in profile thus enabling the Vertical Geometry tools to interact with the chosen feature.
  • Single Element Nudge - Allows the user to move or nudge a single element in a complex geometry.
  • Geometry Connector - Combines multi-element connect, multi-element regression tools and connection editor into one tool.

Spirals

  • Complex Spiral Between - Automatically defines spirals in multiple gaps along the selected complex geometry.
  • Spiral from Element - Used to construct a spiral from a previously places element, using this base element to determine tangency at one end.
  • Spiral Between Element - Used to construct a spiral (or spirals) between two base elements that determine tangency.
