How to set up Road Line rule parameters?

MAGNET Office Modeler provides tools to quickly transform simple linework into a road or a road marking. You can even use your own creativity and utilize this feature for other objects as well.

The Road Lines rule transforms linework into linear, colored areas along the surface. For Road Line model creation, MAGNET Modeler supports 

  • Lines
  • Strings
  • Polylines

Lines, Strings and Polylines with zero elevation can be easily draped onto a surface. 

Elevated Lines, Strings and Polylines can be used as well. This may result in a local adjustment of the surface.

Road Lines rule parameters

1. Layer 

Layer where elements that define the road lines are.

2. Materials 

Click on material to access the Material Library of MAGNET Modeler. Select existing material or insert a new material.

3. Description

Enter a description for the "Road Lines" rule. This will change the name of the rule within the Modeler Rules window. In case you have several "Road Lines" rules, this helps to easily identify them.

4. Group

Click on group to choose from a list of existing groups / sub groups or manually enter your group structure. Use the "/" character to create additional sub groups. For example: Existing/Office/Parking Lot.

5. Width

Width controls the entire width of the road / road marking from the left edge to the right edge. The Line, String, Polyline acts as the center line.

6. Info text

Info text allows to add additional information, such as material, quality requirements, manufacturer, ... The info text information will be accessible in MAGNET Explorer via the Object Info tool.

7. Info URL

Info URL allows to add hyperlinks such as a link to manufacturers homepage or a design documentation. The info URL link will be accessible in MAGNET Explorer via the Object Info tool.

8. Interpolate

Interpolate defines whether the Line, String, Polyline is interpolated to a reference surface or the elevation is taken from the entity itself. It also controls whether the entity follows the ground or stays planar. See examples below for further details.

9. Target layers

Target_layers is relevant when interpolate was set. You can choose whether the texture will only be projected onto a certain surface by selecting the surface from the layers list or if all surfaces are affected (*).

10. Cut

Cut (Yes) will cut out a reference surface within the extends of the Road Line area. This is the default setting. (No) creates a copy of the surface with a slight positive offset and assigns the material to it. (Patch) is similar to (No), however, it creates an optimized copy of the surface by reducing the number of triangles. This is very suitable for road markings.

11. Texture along path

TextureAlongPath defines whether the texture will be mapped as a regular tileonto the surface (analog to a grass texture on a surface) or aligned and scaled by the direction and width of the Road Line rule. 

12. Generation_priority

Generation_priority lets you determine the display order of overlapping Material Areas in the model. (0) - default / layer order, (1) - generates after (0), (-1) - generates before (0).

13. Auto_segmentation_distance

Auto_segmentation_distance densifies the String / Polyline. This parameter is useful for a smoother interaction with a surface when draped.

14. Auto_segmentation_angle

Auto_segmentation_angle divides arcs of a String / Polyline for a smoother interaction with a surface when draped.
