Buildin3d is the fastest way to prepare instructions. NO more PDFs. We support practically all LEGO parts and we show the CABLES!
You can easily protect your IP and securely sell, distribute, and track instructions.
We support LDraw files created by LDCad, Stud.io, MLCad and if you write to us at team [at] buildin3d [dot] com we can even try to import some LEGO Digital Designer files (yes, that’s how long we’ve been around)
