kicad StepUp has a ".ini" file
in home user path:
linux: ~/ ($HOME)
OSX: ~/ ($HOME)
you need to configure your kisys3dmod in the "ksu-config.ini" file to the field
kicad StepUp at the moment doesn't allow more then one single path
prefix for resolving 3D models location... it is partially intentional
because if you have two models with the same name in two different
search path, which one will be picked and would be the picked one the
you can always use a full path for 3D models...
at the moment what you configure under the field
[prefix3D] in "ksu-config.ini"
can be your kisys3dmod or one :alias_path:
StepUp will just look for the 3d models in that path.
I would suggest you to have a tree similar to that:
and use the prefix
as kisys3dmod or alias
Then you can have a folder for github 3D models and a folder for non github ones...
Both folders can have sub-folders as required
