What are DTM Surface Models?

Surfaces are called DTMs (Digital Terrain Model) in MAGNET Office software.

MAGNET Office Modeler provides a rule for surfaces called Surface Models. This rule is able to access one or even several DTMs within Office, assign a material or texture for visualization purposes to it and create a Virtual Model (*VM) out of it.

The Surface Model rule is used to translate native MAGNET Office DTM's into a virtual surface model.

Surface model rule

1. Layer

Click on "layer" to access a list of all available DTMs in your current MAGNET Office project. Select a DTM from the list where the rule should be applied to. You can use the "*" character to select all available DTMs at once.

2. Material

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 surface rule. This will change the name of the rule within the Modeler Rules window. In case you have several Surface Model 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/Terrain/Parking lot.

5. Cut mode

  • No = Surfaces are generated as normal surfaces. Surface model will not interact with any other surface models.
  • Yes = Surfaces will be cut into surfaces generated before this surface. A hole as large as the surface will be created and this new surface will be added to this hole. If the surfaces differ, there might appear holes be-tween the surfaces. Surfaces are not altered in any way.
  • Weld = In addition to “yes” mode the surface edges are connected together so that there is no holes between the surfaces. In other words Surface Model's overlapping area will be merged with any other surface models.
