Sorry if this has been covered elsewhere, but I can’t find any details of how best to handle it.
We are using a git repository to contain custom symbols, footprints and 3D models for our projects. For these parts that we design ourselves, we reference the 3D model path with respect to an environment variable, so the Footprint Properties > 3D Model path looks something like this:
${MY_MODELS}/my_model.step
This means that my colleages can use the parts by defining the environment variable rather than having user directories hard coded in the path etc.
This works well, however we are now running into the situation where there are several parts that already exist in the standard KiCAD libraries we would like to use. They have a 3D model path defined, but no model yet exists. I can provide the 3D model in my custom directory, but I can’t override the 3D model path of the standard library parts. I can copy the parts to my custom library, and update the model path there, which is what I have been doing, but it seems a bit of a kludge, and means they won’t get updated. I don’t really want to put my models in the KICAD6_3DMODEL_DIR directory, as that gets messy to keep updated and runs into permissions issue. Is there a better way of solving this? I notice there is a ‘3D Search Paths’ section in the Configure Paths dialogue which sounds promising, but I don’t really understand how it is different to the environment variables.
Any advice would be greatly appreciated!
