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.Open in New Window
Note: The view used in this video is as follows:
Stack-up: Select All except Powerplane_1 and Bottom
Area: Select All
Geometry: Select All except Dimension
Components: Select All
Manufacturing: Remove All
Drawing Format: Remove All
Note: If you are unsure where your STEP models are stored, select Path under Available STEP packages. This will give you the path for the STEP Model Library.
Note: If needed, set the x, y, or z rotation and the x, y or z offset according to the provided table. To set the rotation and offset, either type the numbers in the desired location or use the increment button. If any PCB footprints have been downloaded from Ultra Librarian through the unified search, the STEP Mapping is already completed for these components.
Note: Under View, select preset views to ensure the STEP file is mapped correctly.
Note: Using the 3D Canvas in OrCAD we will be able to turn this off and on to view our board.
Note: You can select which layers are visible in the visibility tab. You can select which models are visible in the symbols tab.
Note: If this tab is not visible, select View > Windows > Collision Detection from the menu. The problem components will appear in the window.
Note: This will make the component flash for easy detection. You can also select the component from the list. This will highlight the component.
Note: Here you can configure the 3D canvas.
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.
