I recently updated to SW 2020 SP4.0. I just opened a .idx file through CircuitWorks and the PCBA was populated with the colored blocks.
I have had this PCBA opened before (before the SW update) and the default colored components blocks have been replaced with manufacturer's detailed part models, these were copied into the component library and then renamed to to match the names generated in the .idx build that are in the design tree.
Now, even though the design tree names are the same as before, the custom parts are just the colored blocks.
Anyone have any idea why this has happened?
