Documentation for .conn and .col files ? - alphonse - 2026-03-27
Hello,
I'm trying to code my own Lego building engine, and I need to parse .conn and .col files of the parts in order to reproduce the brick snaping feature.
Do you guys know if there is some documentation about how to read .conn and .col files ?
I found this discussion that helped me but it misses some points https://forums.ldraw.org/thread-28521-post-59984.html#pid59984
I also found another discussion about .col files, but same issue, it is not complete :/
Ideally, I would like to be able to scan a .mpd file and get all the available positions for a chosen brick.
Thank you,
Alf

Despite repeated requests to the Studio team, there is not.
I recommend asking on the Studio fourms. Maybe if enough people ask, they'll actually listen.
