Create and update 2D DXF drawings from written requirements or CAD geometry using Python and build123d. Prepare cutting profiles and marking layers, check for open contours and duplicate geometry, and review drawings in CAD Viewer.
Spatial reasoning, coordinate geometry, transformations, and trigonometry for geometric problem solving. Covers Euclidean geometry (points, lines, angles, congruence, similarity), triangle geometry (Pythagorean theorem, laws of sines and cosines), circle geometry (tangent lines, inscribed angles, power of a point), coordinate geometry (distance, midpoint, slope, conic sections), transformations as functions (rotation, reflection, translation, dilation), trigonometry (unit circle, identities, inverse functions), and geometric proof techniques. Use when reasoning about shapes, angles, spatial relationships, coordinate problems, or trigonometric computations.

Create and edit 3D parts and assemblies with adjustable dimensions using cadgen. Export STEP, STL, 3MF, or GLB files, inspect geometry, and open existing models in CAD Viewer for visual review.
Create, edit, and validate SDFormat files that describe robots and simulation worlds. Check coordinate frames, joints, geometry, and physical properties, review models in CAD Viewer, and report assumptions and compatibility risks before simulator handoff.
Create, migrate, refine, or debug CARLA vehicle assets with Blender and Unreal. Use real vehicle references to guide geometry and materials, configure wheels, lights, and physics, and deliver editable sources with evidence from runtime validation.
Create or integrate detailed 3D models with smooth outlines and believable edges for close-up views. Prepare lower-detail versions for distant viewing, prioritize loading, and measure rendering costs in the actual scene.

Create and edit FreeCAD models using commands for dimension-controlled sketches, solid parts, assemblies, and technical drawings. Check geometry through previews, measure models, and export files for CAD exchange, 3D printing, or documentation.
Review Pascal pull requests or branches against documented architecture rules. Check package responsibilities, node extension patterns, state management, and rendering subscriptions to identify misplaced code, compatibility breaks, and changes that could cause excessive redraws.
Modify Handsontable’s Walkontable rendering engine using its architecture and coding rules. The skill covers visible-area calculations, frozen rows and columns, scroll synchronization, browser element measurements, and tests for rendering changes.
Create a manufacturing drawing PDF from a part’s 3D geometry, with projected views, measured dimensions, hole callouts, and a title block. Rerun the drawing script after model changes to update the sheet.
Check mesh files for 3D printing by measuring geometry and comparing it with process-specific design limits. Get findings on wall thickness, overhangs, and supports, plus build orientation options and concrete redesign guidance.
Find CAD models of off-the-shelf parts on step.parts using model names, standards, aliases, and dimensions. Compare matching records, download STEP files when needed, and check file integrity against a supplied checksum.
Import RoadRunner geometry and road data into a CARLA source build, then verify the map loads and supports driving. Handle tiled maps and generate and inspect pedestrian navigation areas for standard maps.
Generate towers, castles, pagodas, and domes in Three.js from adjustable parameters. Create construction animations with a rising reveal, matching solid sections, scaffolding, and stage captions, using reusable geometry instead of imported mesh files.
Plan and integrate assets for Three.js or web games by choosing imported models, code-generated geometry, or 2D media. Define scale and collision needs, check appearance and performance in the game, and record sources and licenses.
