Booleans: a tool wholly inside the target leaves a void (an inner shell); results are oriented outward from a mesh fine enough for every face (a sphere clipping a box's corner came out inside out); as a last resort the tool is nudged by a micron-scale screw motion (tangencies, seams on the other body); a boolean survey test over random boxes, cylinders and spheres

Fillets and chamfers along open chains of curved edges that end at planar faces square to them (the round edge of a D-shaped block): the end faces take the blend's end arcs and their edges stop at the contacts; the curved blend is tried only for curved edges or edges between curved faces, and refuses a blend larger than its neighbouring faces

Fillets and chamfers along closed chains of curved edges between any two smooth sides (a branch pipe meeting a main pipe): a ball rolled along the edge gives the contact curves and the blend (rational B-spline through exact arcs, smooth across the chain's joints); side faces trimmed to the contacts and seams shortened; merged topology joins free-form faces that meet smoothly by their exact normals

Booleans: a face crossed by nested intersection loops (both walls of a tube) gives each hole to the innermost piece holding it (vendored shapeops; tubes and tori cut across now work); revolved full circles start at an odd angle so their seams don't lie in common cut planes

mesh object and build item per body, named after it, vertices shared and
welded watertight (T-junctions between faces split), base-material colours
when bodies carry one (STEP colours now ride on bodies). Tessellation as
for STL. File > Export 3MF.
Import: doc.open/drag-drop/CLI/MCP open accept .3mf and .stl; Insert Mesh
(ParaMeshInsertAlignCommand) adds them to a design as a MeshImport feature.
Kernel mesh bodies render, measure exactly, move and export; solid
features refuse them with a clear error. 3MF reading flattens components
and build transforms, converts units, reads colours; sizes, entries,
nesting and element counts are capped.

M0: truck-based kernel with local fillets and chamfers, parametric document timeline

The kernel moved from monstertruck to truck: truck's booleans handle blind
holes, pockets and bosses that monstertruck's did not (see the ADR). Fillets
and chamfers on straight convex edges between planar faces are our own exact
local B-rep operation. The document holds parameters with unit-aware
expressions and a timeline that re-evaluates incrementally.
