This walk-through demonstrates complete STEP Model mapping and collision detection. After you complete this topic, you will be able to:
To follow along, continue working with the design completed in PCB Walkthrough 9 or open the provided board file in the folder directory, PCB Walkthrough 10_3D Modeling.
If design files were not downloaded in the beginning of the walk-through, they can be accessed through the Materials tab above.
Note: To change the view to replicate what is shown in the video, select the Color button from the toolbar. Change the colors to the following:
Click OK to close the Color Window.
Note: This move is required for proper integration with the mechanical enclosure. If any changes are made to the board, manufacturing artwork and documentation will require regeneration.
Note: When first selecting the 3D Canvas, the 3D Canvas Filter will be activated. Here you can select which portions of the design are included in the 3D representation. Within the 3D canvas, you can select which layers are visible in the visibility tab. You can select which models are visible in the symbols tab. By default, any components without 3D models are represented with a boundary shape. To change this, select Setup > Preferences > Symbol Representation and select the desired display for each symbol.
Note: If this window is not activated, select View > Windows > 3D Mapper.
Note: No adjustments need to be made for these step models as they are automatically aligned to the PCB footprints.
Note: The 3D Mapper includes several options for quick and efficient model mapping including automatic mapping, manual mapping, mapping to the top or bottom of the board, and more.
Note: Select View > Camera from the menu to change the view and ensure the STEP file is mapped correctly. To rotate the board in the 3D Canvas, hold down the SHIFT key on the keyboard and press the middle mouse button.
Note: To turn visibility on/off for mechanical symbols and components in the design select View > Windows > Symbols from the menu. To adjust the transparency of the mechanical models, select Setup > Preferences > Symbol Representation from the menu.
Note: If this tab is not visible, select View > Windows > Collision Detection from the menu.
Note: The Locate command will make the component flash for easy detection. Enable the cutting plane to view a cross section of the PCB to help determine collision and design structure issues. Right click the 3D Canvas and select Cutting Plane. Check Enable Cutting Plane. Adjust the Offset and Tilt in the X, Y, and Z directions for more detail. Right click and select Done when finished.
Note: To rotate the board hold down the shift key and middle mouse button or you can choose preset views by selecting View > Camera in the menu.
Note: The changes will appear automatically in the 3D view once the part is placed.
Note: Delete the existing traces. In the Design Window, select Interconnect > Manual Routing > Add Connect. Click to place the trace. Right click and select Done when finished. In the Design Workflow, select Display Status to confirm the routing.
Note: The errors have been resolved and only the collision between X1 and the USB is reported.
