(Yesterday, 21:37)N. W. Perry Wrote: Now on to LDView. When I open the same part in LDView, the custom primitive isn't found, even though both User and User/p/ are set as extra search paths. To make the prim appear, I have to change the pathname to the full pathname from my disk (so Users/nwperry/ldraw/User/p/48/prim.dat).
I just tested on my Mac, and LDView 4.6 was able to find 48/user-p.dat in <ldraw dir>/User/p/48 when <ldraw dir>/User/p was in its extra search dirs. This is the expected behavior, so I'm not sure why it wouldn't work for you. What OS are you using?
