Roads & Trenches

The Roads & Trenches dialog displays a list of the roads in the current job, and the plot of the selected road in the horizontal and vertical planes.

The icon brings up the pop-up menu of additional options. More...

Note: When editing or deleting a road or its element (horizontal/vertical alignment, X-section/template/X-section set), you may get a message that the respective object "is read-only and cannot be edited". This happens if you are working with a job that was originally created in Kantoku 3D software and had road/road elements imported from RSM XML format.

RSM stands for Road Shape Management.

Intersection Point

To create a compound curve between two intersecting HA elements.

Note: The HA element after the Intersection Point element should not be tangent to the HA element before the Intersection Point element.

The Intersection Point element normally consists of a straight line segment, which is usually tangent to the previous HA element, an optional incoming spiral, a circular curve, and an optional outgoing spiral, which is tangent to the next HA element.

To create a compound curve:

  1. In the Point field, specify the intersection point of previous and next HA elements. Enter a point name manually, or select from the map or from the list of job points. Alternatively, enter manually plane coordinates (North and East) of the intersection point in the respective fields.
  2. The North and East fields display the plane coordinates of the intersection point; they cannot be changed if an existing point is selected.
  3. Enter the Radius of the circular curve or one of the two parameters unambiguously defining the radius: Chord Angle or Curve Angle.
  4. Enter either the Length or Spiral Constant for incoming spiral 1 connecting line segment to circular curve and outgoing spiral 2 connecting circular curve to next HA element). The Spiral Constant is the square root of the length multiplied by the radius of the spiral at the end point.
  5. Click to include the Intersection Point element to the horizontal alignment. The application creates a compound curve, after directions of previous and next HA elements are defined.
  6. Note: It's possible to include an Intersection Point element to the horizontal alignment at any time. Use the Add button in the Element tab of the Edit Horizontal Alignment dialog to add the intersection point after the last element in horizontal alignment, use the Insert button to insert the intersection point before the highlighted element. The compound curve is created after both HA elements (before and after the Intersection Point element) are defined.

Note: When editing or deleting a road or its element (horizontal/vertical alignment, X-section/template/X-section set), you may get a message that the respective object "is read-only and cannot be edited". This happens if you are working with a job that was originally created in Kantoku 3D software and had road/road elements imported from RSM XML format.
