Maybe the plugin is too restrictive on the format; it’s expecting the property element attributes to be all on one line? I.e.
(property "Reference" "Q"
This can happen if the plugin is doing line oriented processing. But the S-expression format just treats newlines as white space, so putting “Reference” and “Q” on separate lines is legal syntax.
You should take this up with the plugin’s author.
The native importer hardcodes 3D model paths to ${KIPRJMOD}/EASYEDA_MODELS/, so if you add the lib globally, it won’t find the 3D models from other projects.
So it’s recommended to add the .elibz file to local library tables.
