Using Linear Select to Add Bridges, Tunnels, Cuttings, Embankments and Magic Round-Abouts to Tracks

Ortelius provides a unique tool for selecting sections along a longer track called Linear Select. Use the tool as you would a highlighter to select a portion of a track for applying inline styles, style adornments, labels, and other special features, such as a magic roundabout. Handles on these special features provide “just right” positioning along tracks.

To Use Linear Select

Ortelius’ exclusive Linear Select™ tool works like a highlighter.

  1. Choose the Linear Select [n] tool.
  2. Press and drag over a track, highlighting as you go, then release.

HINT: While a path may look similar to a track, tracks have special properties. Linear Select does not work with regular paths.

To Apply In-line Styles

In-line styles are new styles applied in-line with a single track, replacing the section highlighted with Linear Select with a new style. A transition is applied between one linear style and the other.

  1. Use Linear Select [n] to highlight a portion of a track that will receive the new style treatment.
  2. Do one of the following:
    • Double-click the desired style in the Styles & Symbols palette to apply it to the selected section, or
    • In the Styles Tab, click ‘Reset’ or ‘Clone’ then create a style to be applied to the linear section.

To Change the Transition of In-line Styles with Width Adaptors

Ortelius creates beautifully smooth transitions between styles of varying widths using Width Adaptors.

With the track selected, open the Geometry Tab. Choose from one ot the following Width Adaptors:

  1. Blend (the default for style transitions)
  2. Wider
  3. Narrower
  4. Midway
  5. Average
  6. None

To Adjust the Position of an In-line Style

In-line styles positioning handles give you “just right” positioning.

  1. With the track selected, drag the green knobs at either end of the in-line style to reposition it.

HINT: To hide in-line style positioning handles to reduce visual clutter and/or reduce the problem of having ambiguous targets for mouse clicks, uncheck "Editable style boundaries’ in the Geometry Tab.

To Remove an In-line Style

Do one of the following:

  • Right-click the track in-line style and choose Remove Style ‘Name’ from the contextual menu.
  • Use the Linear Select [n] tool to highlight the section of track containing the in-line style and choose Edit > Paths & Tracks > Unify Styles from the main menu.

To Insert a Tunnel on a Track

Tunnels are in-line styles (they replacing the section highlighted with Linear Select with a new style).

  1. Use the Linear Select [n] tool to highlight the section of track to accept the tunnel.
  2. Choose Insert from Geometry Tab and choose ‘Tunnel’. The tunnel will be automatically inserted and styled to match the road style.

To Remove a Tunnel from a Track

Do one of the following:

  • Right-click the track and choose Remove Tunnel from the contextual menu.
  • Use the Linear Select [n] tool to highlight the section of track containing the tunnel and choose Edit > Paths & Tracks > Unify Styles from the main menu.

To Apply Overlay Styles

Overlay styles are style adornments applied in addition to the existing style of a track. Bridges, overpasses, cuttings, and embankments are available overlay styles. These special features are smart and will adjust certain style properties, such as line weight, according to the line style of origin.

  1. Ue Linear Select [n] to highlight a portion of a track that will receive the new overlay style treatment.
  2. Choose Insert from the Geometry Tab and choose the desired feature to be added.

  2. Choose Insert from the Geometry Tab and choose ‘Overpass’.

To Insert a Cutting or Embankment on a Track

During highway and rail construction, land may be raised to create a level surface, forming an “embankment.” Alternatively, the land surface (for example, a hill) may be “cut through” to allow the road or rail surface to remain level. These features are referred to as “cuttings.” Cuttings and embankments are traditionally shown on local (large) scale maps.

Cuttings and embankments are overlay styles (they are applied in addition to the existing style of a track).

  1. Use Linear Select [n] to highlight the section of track to accept the cutting or embankment.
  2. Choose Edit > Insert Special > Cutting (or Embankment) from the main menu.

To Adjust the Position of an Overlay Style (Bridge, Cutting or Embankment)

Do any of the following:

  • With the track selected, drag the left handle (yellow circle) on the overlay style (bridge, cutting or embankment) and slide it along the track for fine-tuned positioning.
  • Drag the right handle (orange dot) on the overlay style to adjust its length.

To Remove an Overlay Style (Bridge, Cutting or Embankment)

  1. Use the Linear Select [n] tool to highlight the section of track with the overlay style.
  2. Choose Edit > Paths & Tracks > Delete (overlay style) from the main menu.

To Create a Custom In-line or Overlay Style

If the predefined special styles available in the Edit > Insert Special menu are not to your liking, you can create new bridge, tunnel, cutting, or embankment styles.

  1. Use the Linear Select [n] tool to highlight the section of track to accept the new style.
  2. Open the Style Tab and click ‘Clone’ to base your new style on the existing track style, or ‘Reset’ to create a new style.
  3. Add one of the following ‘Adornment’ style components: ‘Bridge’, ‘Tunnel’, ‘Cutting & Embankment’ to your new style.
  4. Adjust the style component properties as desired.
  5. Save the new style to your user library.

To Insert a Magic Round-about

At the junction of two or more connector tracks, the magic round-about places a circle in the parent track’s style, sized according to the width of the line style, with junctions made fully automatically. After placement, the round-about is an editable section of track.

  1. As needed, use the ‘Path Cutter’ tool to make a junction. The cut track (shown in yellow) becomes the "child" to the "parent" track.
  2. Use the Linear Select [n] tool to select the length of a "parent" track along the junction with one or more child tracks.
  3. Choose Edit > Insert Special > Magic Round-about.
