1. The 3D PCB Viewer

The 3D PCB Viewer for Protel 99 brings a new dimension to PCB design.
Now you can examine the finished board before you build it - 
rotate it, zoom in and out, check the bare board, highlight nets on 
the board, or print the 3D view. The viewer uses sophistocated 
component modelling technology to present a real-world 3 dimensional 
view of your board.

====================================================================
2. Installing and running the 3D Viewer

- Ensure that Protel 99 is closed prior to installing the 3D Viewer.
- Double-click on the Setup.exe file to start the installation 
  process 
- Follow the instructions in the installation Wizard

To view a PCB in 3D mode:
- Re-start Protel 99
- Open the PCB document
- Select View » Board in 3D from the PCB Editor menus

Once the board has been analyzed it will be displayed in a separate 
3D Window. 

- Click and drag in the MiniViewer window in the Panel to rotate 
  the board
- Use the standard PCB shortcuts to change your view of the board

The 3D Viewer uses the boundary on the keepout layer to generate
the board outline. The tracks/arcs that make up the boundary must
be completely closed, that is their ends must overlap so that the 
center point of one track end touches the center point of the 
adjoining track end on the boundary.

====================================================================
3. How components are modelled

The 3D Viewer uses an in-built component classification system to 
automatically select an appropriate component model. This release
does not support user-selectable component models.
