Not a mockup. Every line on this sheet was drawn by the tools this server exposes — ISO layers, involute gear geometry, DIN 6885 keyway, section A-A, ISO 129 dimensions, an ISO 286 H7 bore fit, ISO 7200 title block — then rendered headlessly by view_screenshot. drawing_critique returns 0 issues on it. Rebuild it with python scripts/render_readme_showcase.py.

v1.6 release snapshot: 247 tools · 8 resources · 5 prompt templates · 4992 collected tests. 247 is the registered count; a default install advertises 242 over tools/list, because ENABLE_3D is unset. system_about is the runtime authority.

What's new in 1.6

Five tracks of one roadmap, 154 → 247 registered tools. Each track has its own design spec, correctness checks that can fail, and a live AutoCAD 2026 run of its COM paths recorded in the changelog.

Track	What it adds	Pack
P&ID — drafter and reader	43 ISO 10628-2 / ISA-5.1 symbols as real blocks with ports and TAG attributes, port-to-port lines with ISA-5.1 classes and line numbers, pid_graph reading any P&ID back with a confidence per node, instrument index, line list, equipment list, pid_from_spec for a whole sheet in one transaction	pid
The AutoCAD environment	ISO-25 / ANSI dimension styles, text and leader styles, drawing_apply_standard, ISO 216 / ANSI page setups checked against the plotted PDF's own /MediaBox, five bundled templates, several open documents headlessly, portable layer states, named views, UCS, a 90-entry system-variable catalogue; on a live seat, preferences, launch and operator prompts	core, settings
Mechanical parts and the sheet	one part model and one view engine (front, side, top, section and detail views with hidden lines, cut faces and ISO 129 dimensions), ISO fasteners and bearings as blocks with attributes, ISO 21920-1 surface texture, ISO 2553 welds, ISO 5457 frames A4–A0, ISO 7200 title blocks, an ISO 7573 parts list read off the drawing with linked ISO 6433 balloons, xrefs, images, real .dwg	mech, core
Architecture	walls with hosted doors and windows: one engine resolves L / T / X junctions and cuts the openings. Room areas are measured from the faces the walls enclose, and rooms are read back from any plan. Door / window / room schedules are real tables; labels in English or Turkish	arch
Understanding and takeoffs	drawing_understand reads a drawing somebody else made in one call. Also drawing_scale_check, drawing_diff and drawing_topology_check. pipe_takeoff / cable_takeoff take the topology from the P&ID and the lengths from the layout into a Turkish, English or Russian workbook	core, plant
