Options

Use this dialog to change construction settings for the main surface and side surfaces (cut/fill), as well as other settings for labeling and displaying information in intersections.

The main surface is constructed based on 3D lines from Kryss3D. Side surfaces are constructed using cut/fill parameters inherited from the involved roads.

Where do I find the dialog?

In the toolbox in the terrain model drawing, select the Intersection icon, then the Options tab.

Parameters for Kryss3D

Here, you decide whether the shoulder should be constructed from cut/fill parameters or from 3D lines calculated in Kryss3D. If you check Construct shoulder with cut/fill parameters, the shoulder is set to 0 in Kryss3D, and the parameter for the shoulder surface is inherited from the roads. This is the default option.

The advantage of constructing the shoulder from cut/fill parameters is that you can have different slopes for the carriageway and the shoulder, as well as specify different presentations.

Warning

You must close the intersection dialog, reopen it, and create a new intersection or edit an existing one if you change this option.

Parameters for Cut/Fill

The intersection inherits cut/fill parameters from the involved roads. The surfaces defined by these parameters are constructed in profiles along the shoulder edge or road edge lines, depending on what is set under Kryss3D parameters. The constructed surfaces form the basis for the side surfaces' triangle net.

How the program generates these profiles is determined by the parameters profile distance, right side distance, and calculate from adjusted terrain.

Parameters for Triangulation

The program triangulates the result lines from Kryss3D. You can find these lines in the layers tab. These may be lines within the shoulder edge or road edge, depending on the settings under Kryss3D parameters.

For island lines, you can specify additional parameters:

  • Curb height: Applies to all traffic islands.
  • Curb width: Computationally intensive operation. Set width to 0 if you do not want to include this.
  • Central island center height: Height at the center of the central island, relative to the driving height of the central island.
  • Central island driving width: Width of the drivable part of the central island.
  • Central island driving height: Height of the driving lane in the central island (inner boundary), relative to the height of the road edge (outer boundary).

Common Parameters for Cut/Fill and Triangulation

In the Max. circle deviation (XY and Z) field, specify the maximum value for the chord height in curves. The figures below show the effect of different values for circle deviation.

The program divides the curves into line segments based on the requirement for maximum circle deviation for triangles.

Point Labeling

In this group of options, check the lines that should be available for labeling in the plan view. The points are also included in the mass report.

Grid Density for Mass Drawing

Here, specify the grid density that the program should use when drawing the mass result in plan and 3D. This option takes effect if you have checked Draw masses in the properties tab.

Note

The highest density that takes effect is determined by the setting under Gemini Terrain Settings... - Project - General.

Interval for Elevation Labeling

The labeling line is one of several lines with different functions. Use this line to add elevation labels. Interval for elevation labeling determines how closely you want to label elevations along the line. Only the labels are shown on the screen; the line is invisible except during editing.

Note

0 in the field means you only get elevations at the break points.
