Scaling files

[John]

I couldn't find this in the archives ..

If you have a file for an HO scale model, can you reduce it to N scale by using the scaling feature in Chitubox, or does the model have to be resized in a cad program?

Not only you have to worry about rendering the small details after shrinking, but things like wall thickness of hollow shells might also end up being too thin for the printer to handle (or just too flimsy to be useful).

This.

Generally you want around 2mm for wall thickness to retain stability so for files that I shrink I generally import into Meshmixer and verify that walls are at least 2mm.   I test printed some 30yrd dumpsters without checking and it produced some interesting results when going from 1:1 to 1:87. Need to tweek the file after the first print.
