Welcome to the A:M forum, Phaedrus!
I'm not a Library icon expert but this... orient the model in the model window to how you'd want the icon to appear, then >Create Icon and then resave model. I think that will do something.
Thank you Robcat2075
Alas I suppose I should have mentioned I'm still running AM2004 version 10.5
I don;t see a Create Icon with the "right mouse click" in the model window.
Thank you though
