Suggested Design Sequence
To best integrate Creo Parametric with the ECAD design process, use a sequence like this:
1. Create 3D parametric models of components—Import each component outline that you will use from the ECAD system library into Creo Parametric, and use it as a basis to create a more detailed 3D model as a part file. When you import the board outline and placement information into an assembly, you can substitute these parts for those that would automatically be created on import.
2. Parametrically design the board outline—(complete with cuts, mounting holes, and keepin and keepout areas) as a part file. You can also define keepin or keepout areas for export to the PCB designer.
3. Create an assembly and place the board part into it—Using the 3D component models, place parts whose placement should be determined by heat or physical obstruction considerations.
4. Export the assembly as board outline and component placement information—The keepin and keepout outlines are also exported with this information. For export, select one of the available ECAD formats.
When the PCB designer has completed placement, you can import all component placement information into Creo Parametric to check for interference between components and other physical obstructions in the assembly.
Use Creo Parametric to make any necessary component placement corrections. Export the board back to the PCB designer to demonstrate the new placement.
Finally, perform a final mechanical analysis of the completed board in Creo Parametric.
