Guide

The guide covers one concept per page, in the order a build meets them.

  • Four slopes, one in each rotation

    Coordinates

    Studs, plates and exact integers: where at puts a part, and how rotations work.

  • A round tower filled from voxels with bricks and plates

    Build scripts

    Python that places parts, reuses components, fills voxels and builds sideways.

  • One part of each family on a baseplate

    Parts and colors

    How to find a part, and the shape each family gives it.

  • The broken example, every element an error names tinted red

    Checks

    How to read a report, set the level of each rule, and see what changed since the last build.

  • A crane whose jib stands on one stud of its mast, tinted orange

    Stability

    Whether a model stands under its own weight, and how hard its studs grip.

  • The cottage with its roof highlighted

    Images

    The sheet every build renders, single views, highlights, clips and the 3D viewer.

  • One part of each lot on a baseplate

    Exports

    The parts a model needs, as a BrickLink Wanted List to buy them.

  • The cottage half built, the roof slopes of step 17 outlined

    Instructions

    Steps to build a model, in an order that straight moves can follow.

  • A slope and an arch beside the voxels they fill

    Voxels

    The grid that compares a model with a plan or with another model, exactly.

  • Parts converted from LDraw: a Technic brick, a window, a log brick and more

    Catalog

    Where parts and colors come from, and how to import all 97,099 parts.
