Tutorial: Adding unofficial LDraw parts to MLCad

[Chris Dee]

That's also why I never use the "parts update".exe. It doesn't only adds the new parts. It also adds all the official files.
I don't want to have the files that are not ready for release, reinstated in my official folder.

I don't understand. If you mean by "parts update".exe the Windows installer for the complete library (e.g. LDraw1401.exe), that only installs parts that are ready for release, but you are correct that it re-installs the entire Official Library. It does NOT install files that are not ready for release.
