How to set up Element chain rule parameters?

Element chain rule allows you to create chain of elements such as row of trees or light poles.

Typical objects for the Element Chains rule are:

  • Stand of Trees
  • Street Lamps
  • Solar Panels
  • Power Poles
  • Other equally distributed Elements

The Element Chains rule transforms linear objects such as 

  • Lines
  • Strings
  • Polylines
  • Arcs

into single, equally distributed elements following the trajectory of the entity. In case of zero elevation, all objects can also be translated to reference surface.

Element chain rule parameters

1. Layer 

Click on layer to access a list of all available layers in your current MAGNET Office project. Select one or multiple layers from the list where the rule should be applied to.

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 Element Chains rule. This will change the name of the rule within the Modeler Rules window. In case you have several Element Chains 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

Enter a value for width to control the width of the texture. If this attribute is empty, the texture is controlled by the material properties (defaultwidth).

6. Height

Enter a value for height to control the height of the texture. If this attribute is empty, the texture is controlled by the material properties (defaultheight).

7. Randomness_size

You can apply a randomness_size by applying a percentage between 1 and 100.

8. Density

Change the density attribute to set the elements spacing along the linear entity.

9. Info text

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

10. Info URL

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

11. Interpolate

Interpolate (bottom) drapes the entities to the surface. The insertion point of the texture is at its center bottom. Interpolate (top) uses the entities elevation as the top of the object and stretches the texture down to the surface. This overrides both the width attribute and the defaultwidth. Interpolate (none) uses the entities elevation as the bottom of the object and assigns either the width attribute or the defaultwidth.

12. Position_offset

Position_offset allows a relative X, Y, or Z translation.

13. Rotating

Rotating (Yes) will automatically rotate the object to always face the viewer.

14. Rotation

You can change the direction of the object by editing the rotation value. 0 equals the X-Z plane.

15. Z_rotating

Z-rotating correlates with Z-rotation. Set it to (Yes) to rotate the Z-axis.

16. Z_rotation

Z-rotation will rotate the Z-axis. Setting this 90 will result in the picture lying on the ground.

17. Background_material

In case Rotating is set to (No), you can define a background_material, visible on the backside of the picture. If this is not set, the alpha channel of the picture is used. This means it looks the same from both sides.

18. Alignment

You can use the alignment option to align the object perpendicular to the surface triangles (surface) or leave it always vertical (normal).
