n3r/AgentCAD

assemblies-and-mates

Declaring named connection frames with a connectors(p, part) function and positioning assembly instances by mates - rigid, revolute and cylindrical joints, the anchor rule, and the mate forest.

原文语言：英语

brackets-and-mounts

L/U/Z brackets, gussets, bolt patterns, adjustment slots and NEMA motor mounts — sizing, clearances, load path, and the build123d order that survives a rebuild.

原文语言：英语

design-specs

Executable design intent - SPECS declarations checked on every rebuild, the part/assembly/FEM tiers, requirement traceability, and the spec-first workflow the checks tool and geometry CI consume.

原文语言：英语

enclosures

Two-part boxes, housings and cases - wall thickness per process, shelling, lid lips and grooves, screw bosses, PCB standoffs, vents, draft.

原文语言：英语

fdm-design-rules

Design rules for FDM/FFF 3D printing — wall and feature minimums, 45 deg overhangs, bridging, teardrop holes, elephant foot, warping, orientation, tolerances.

原文语言：英语

fem-workflow

Running and reading AgentCAD FEM — fem_static, fem_modal, fem_thermal — fixture and load faces, mesh size, safety factors, deflection limits, material_basis, and what not to trust.

原文语言：英语

fits-and-clearances

Sizing mating features — ISO 286 hole-basis fits (H7 with g6/h6/k6/p6), printed-part clearances, bearing seats, dowel pins and heat-set insert holes.

原文语言：英语

holes

The hole wizard - clearance, tapped, counterbore, countersink and drilled holes from ISO/ASME tables, the plane predicate, per-instance verification and the machine-readable hole record.

原文语言：英语

patterns

Repeating features with agentcad.toolkit.patterns - bolt circles and grids as point sets, linear/polar/mirror shape patterns, the seed-counting convention, and why every helper returns a warning.

原文语言：英语

ribs-bosses-draft

features.rib, features.boss and features.draft - stiffening ribs, screw bosses and mould draft, the plane predicate, draft's low ceilings, and the silent fuse when a feature misses.

原文语言：英语

robust-parametrics

safe_fillet, safe_shell and safe_bool - the toolkit helpers that survive OCCT's sharp edges - plus the guards that keep a parametric script building across its whole parameter range.

原文语言：英语

selectors-and-occt-failures

Picking edges and faces with ShapeList selectors, and reading OCCT failures - fillet radius, degenerate booleans, shell openings, loft order, Hole with no material, sweep self-intersection.

原文语言：英语

sheet-metal

SheetPart - one spec yielding both the folded solid and the flat pattern, with bend allowance and K-factor, partial flanges, automatic bend relief, hems, corners and SVG/DXF export.

原文语言：英语

sketch-solver

The 2D constraint sketch solver - points, lines, arcs, ellipses, splines and slots under geometric constraints, reading dof and diagnostics, and emitting build123d source for the solved profile.

原文语言：英语

snap-fits

Cantilever and annular snap-fit design - beam length and taper, permissible strain per material, undercut, insertion and return angles, catch clearance, FDM orientation.

原文语言：英语

threads-and-fasteners

Simple vs real ISO threads, threaded rods, cap screws and hex bolts, boring a tapped hole at root_radius, and the male/female interference every assembly check trips over.
