These tools calculate and generate various LDraw files useful in parts creation. I wrote Isecalc and Linetrim programs while creating spokes of wheel 55982 as calculating intersections of spokes (60° apart) with rims cylinders (facets 22°5 apart) was tedious at best! Ytruder was created for engraved lettering that I needed to model the NXT brick.
Coverer utility creates a sheet of triangle and quads between two sets of lines. |

Dat2QP is a tool written in C++ by J.C. Tchang. It allows to convert a LDraw file into a Quad2Dat one. |
|
Tutorial describing the use of Lee Gaiteri's Edger, an optional lines calculator (tutorial written by J.C. Tchang) |
|
Isecalc utility computes the intersection line of two sets of triangles or quads. |
|
Intersector utility allows to cut a LDraw file along the intersection with another. |
|
Linetrim cuts lines going through triangles or quads (Obsolete tool, replaced by Intersector). |
|
OLC is a program written by Richard Baxter, which adds optional lines (LDraw line type 5) between polygons of a file. |
|
PathTruder utility allows to create a surface by extrusion of a shape along a path. |
|
PlanarCheck verifies that all quads of a part file are planar enough to fulfill LDraw.org Parts Tracker requirements. |
|
Projector utility allows to stamp a flat pattern over a 3D former |
|
Rectifier utility optimizes a LDraw file by converting adjacent triangles into quads and transforms rhombuses bordered with lines into rect primitives |
|
Ytruder utility creates a sheet of triangle and quads from a set of lines, by extrusion in LDraw Y direction. |

This tutorial describes how I created the finger of 50914 part, using several tools. |
All these command line tools can be more easily used thanks to LETGUI, a user interface written by Michael Heidemann.
