  - Radio Coverage Solution
    This example considers the application of analyzing a Wi-Fi router in a building.
    - Example Overview
      This example shows how to define and set up a radio coverage solution in Altair SimLab. The model is a single-storey building with doors and windows, solved using the Dominant Path model (DPM). The model is solved and the results are displayed.
    - Topics Discussed in this Example
    - Example Prerequisites
      Before starting this example, ensure that the system satisfies the minimum requirements.
    - Launching and Configuring SimLab
      Open SimLab and configure SimLab to only show the tools relevant to the selected solution.
    - Navigating the Graphics Window
      The graphics window is used to display and interact with the model. You can zoom, rotate and pan a 3D model using the keyboard, mouse, or a combination of both.
    - Defining the Sketch Plane
      Set up the XY plane as the sketch plane. The floor plan will be drawn on this plane.
    - Setting the Model Units
      Change the model units to meters, kilograms, and seconds.
    - Creating the Building Geometry
      Use 2D sketches to define the building floor plan, doors, and windows. The sketches are realized as single sheet bodies to create the building geometry.
    - Adding Material Properties
      To add material properties to the ceiling, doors, floor, windows and walls, the materials first need to be loaded from the Material Database. A property can be defined and assigned when the material is loaded into the model.
    - Hiding Selected Objects in the Graphics Window
      To make placing the antenna in an upcoming topic easier, hide the ceiling for now.
    - Defining a Radio Coverage Solution in SimLab
      Create a radio coverage solution for the model (bodies).
    - Adding an Antenna
      Add a Wi-Fi antenna to the model.
    - Adding a Prediction Plane
      Define a prediction plane where the results are to be predicted when running the WinProp Solver.
    - Specifying the Propagation Model - DPM
      Select the Dominant Path Model (DPM) as the computation method.
    - Defining the Result Requests
      Specify the predictions to be computed.
    - Solving the Model
      Compute the propagation for the antenna to obtain the prediction results.

Navigating the Graphics Window

The graphics window is used to display and interact with the model. You can zoom, rotate and pan a 3D model using the keyboard, mouse, or a combination of both.

Panning the Model

Press and hold down the right mouse button, and drag the view to pan (without magnification).

Rotating the Model

Use one of the following methods to rotate the model:

Press the mouse wheel and drag the view.
Note: The rotation center point updates dynamically when clicking on the model.
On the View toolbar, click the Views icon and select one of the following:
- Rotate clockwise
- Rotate counter clockwise
- Rotate left
- Rotate right
- Rotate up
- Rotate down

Zooming to Extents

Use one of the following methods to zoom the model to extents:

Press F to zoom the model to the full extent of the graphics window.
On the View toolbar, click the Fit View icon.

Zooming In / Out

Use one of the following methods to zoom in and out:

Scroll the mouse wheel.
Press Ctrl and hold, left mouse click and drag model.
