_This is the English reading version of the Dutch news item [MitCAD is not finished yet and already has a very impressive parts library!](https://opensourcecad.nl/nieuwe-cad-apps/mitcad-onderdelenbibliotheek-in-het-programma/)._

Mitcad’s parts library was updated to version 2.9.0 today: lots of parts you can
drag straight into your assembly.

Bolts and nuts were there from the start. The library began on 8 October as a fastener
library and was renamed the parts library on 16 October. What was added in the weeks
after that is the rest: profiles and connectors for six aluminium profile systems,
sheet material, timber and wood connectors, steel tubes to EN 10219-2 and EN ISO
1127, bearings, linear guides, gears and belts. 766 parts in all.

What is more remarkable than the contents is where it sits. The library is a git
repository that you fetch yourself, and at the start Mitcad already has its own 
library in the list, with an index of libraries by others. A design remembers which
version it used, so older designs keep working when the library is updated, and 
automatic updating stays off until you switch it on. Putting a library of your own
on a shared folder works too. The licence is listed per part: the library under 
the MIT licence and the fasteners under CC0.

The parts library in Mitcad, with the socket head cap screw in 448 sizes and the
standard and the supplier part numbers for each size.

**My verdict:** a library like this is the dream of many an engineer, and in FreeCAD
it was hidden away in an addon. And it does not belong in an addon, it belongs with
the assembly workbench. It is good to see that a good UI and buttons you can actually
find are possible in an open source package too, instead of the hunt through wiki
pages, macros and addons. I have [tested Mitcad myself](https://opensourcecad.nl/en/continue-your-freecad-design-in-mitcad/):
it took literally 2 minutes to download and install the library. And this program
is not even finished yet and it is already in there properly! My compliments to 
MitCAD. Keep an eye on this site for updates and tests, I will keep following the
parts library.
