How are you using Circuitworks? Is the ME defining the board outline, keepouts, and some major components and then sending it to PCB Layout? What ECAD are you using? How do you handle changes? What do you make sure to include? Do you create a drawing that goes with the CircuitWorks output?
We have Circuitworks, but I'm not sure that there is much advantage for me to using it compared to just sending a DXF. We do a lot of different things (limited reuse of designs) and don't do layout in house. We also don't have a dedicated librarian, so I'm not sure we have time to coordinate the origins of the MCAD models and the ECAD symbols. How do you overcome these obstacles? At this point, we're leaning away from using CircuitWorks.
We are using SolidWorks 2016. Most of our layouts are done in Allegro, but occasionally, we do layout in Altium.
