3DToLD is a program for converting various 3D file formats to (LDraw) DAT files.
Tool to get the part difference between two LDraw files
Browser-based 3D editor and physics simulator for LEGO Technic mechanisms, with LDraw and Studio .io import, smart connections, motors, gears and collisions.
Draw a loop around some gears and get the chain that fits as an .ldr.
Join parts creating weird angles and get an ldr you can import in Studio
LEGO Alternate Build Companion App for MOC builders. Allows builders to easily track the parts they've used and compare against the original set inventory.
This small C# console tool takes in a 3D LEGO BrickLink Studio .io model, calculates its center of mass, and writes a new .io file with a red technic ball (part 32474) marking the balance point.
This repo ensures correct color mapping when importing LDraw files into BrickLink Studio, so your parts no longer show up black.
