[LDCad] Help with Donor files

[Philippe Hurbain]

Thank you Philippe,

good to see, that I was not totally wrong 

I placed everything in the right folders but it seems like a submodel is missing.

I double checked, that I got all the mentioned submodels but it still looks like in the attached picture.

Do I have to search the failure at my side or is something wrong with the model ?

Looks like you're missing 48\7-8ring2.dat primitive (which is indeed listed in this train wheel dependencies). This high res primitive should go into ldraw\p\48 folder.
But instead of hunt and peck all missing files, it would be easier to download and install ALL unofficial files at once, you can get them from https://www.ldraw.org/library/tracker/
