Re: End to end examples in CAD
Somehow your suggestions with end-to-end and then LOD gives no sense at all. And even the best CAD in the world need LOD and lightweight loading system, because else it is not compute-able and represent-able via GUI and/or RAM, besides the whole fiddling around with really unnecessary details.
Do not forget, that if are the unnecessary are in the CAD, they gives also an unnecessary big rat-tail in all kind data and handling work afterwards, like PDM/PLM handling (excluding handling, exceptions, ....), BoM (same), ERP (if they land accidentally there by former handling (PDM/PLM/BoM errors, unnecessary!) you have to rework all in the ERP), same in production order, purchase requisition, ..... all because unnecessary details are in the model and there is a change to mess things in the workflow line, the rat-tail afterwards is very big. Unnecessary details does not legitimate to be in the CAD model.

Re: End to end examples in CAD
Hi @askoh,
We would like to have something similar to what you proposed. We are building machines that are constructed for specific use cases and only a few are built from each configuration (e.g. 20-30). At the same time, we need to keep the costs down and build systems that are built from mainly off-the-shelf components and are easy to assemble.
My plan is to use FreeCAD to help with this by creating a CAD model that also includes everything for manufacturing, including BOM (with information on where to source each component including pricing information) and step-by-step building instructions.
The good news is, that we are not the only ones interested in this: apparently, there was a presentation at the FreeCAD Day in February about automated documentation for open-source hardware from a properly annotated FreeCAD model. Check out the code here: https://codeberg.org/osh-autodoc/osh-autodoc-workbench (They have live ISO for testing + a video for an overview). I could not find a recording of the FreeCAD Day presentation, but the author @pieterhijma is on the forum, and he posted about the project here: viewtopic.php?p=657583#p657583
