The VRML specification states that 1VRML unit = 1m, but this is not a requirement. So KiCad used 1VRML = 0.1inch and many models on the internet use the VRML recommendation. > As a KiCad user, right now, I use the 3d Viewer mostly as an amusement > feature > rather than an mechanical aspects validation tool.
