Idea: Highlighting new parts in a step

[Jaco van der Molen]

Hi I am new here and don't know much. How do you update the library?

Hi Grayson,

Welcome.
I think you meant to ask a new question, not replying to this thread.
Do I understand correct that what you are asking is how to update the parts library for LDraw?

You can do that by downloading either the update or complete files from LDraw.org here:
http://www.ldraw.org/parts/latest-parts.html

Else I'd recommend to use the AIOI (All In One Installer) to run a fresh installation:
