# Cad Bot Cad Bot is a text to CAD generator: a plain-English part description becomes a downloadable 3D CAD file (STL and STEP) and a 3-view shop drawing (DXF and DWG). The product is Cad Bot at aicadbot.com — not AutoCAD text editing, and not AiCadGen. The AI parses the sentence; a deterministic geometry compiler builds the solid, so stated dimensions are exact. Named parts without sizes still get a starting solid (assumed dimensions, then sliders). Sign in is required to generate. Unpaid accounts get 3 free generations per UTC day; parameter slider rebuilds are free. Paid Starter and Pro monthly plans are listed on /pricing. Scope: one solid as a plate, box, cylinder, tube, square tube, L-bracket, U-channel, I-beam, T-section, Z-section, DIN rail, strut channel, T-slot extrusion, hex bolt, hex nut, socket-head screw, button-head screw, countersunk socket-head screw, carriage bolt, pan-head screw, cheese-head screw, slotted countersunk screw, round-head screw, set screw, shoulder screw, eye bolt, eye nut, coupling nut, castle nut, roll pin, taper pin, clevis pin, solid rivet, R-clip, square nut, T-nut, fender washer, wave washer, disc spring, extension spring, torsion spring, knurled nut, thumb screw, shaft collar, V-belt pulley, sprocket, gear rack, internal gear, heatsink, wing nut, flange nut, cap nut, spring washer, toothed washer, internal toothed washer, circlip, internal circlip, E-clip, O-ring, woodruff key, cotter pin, hex key, flanged bushing, U-bolt, coil spring, spur gear, hex bar, parallel key, gib-head key, round-end key, dowel pin, hex standoff, lag screw, J-bolt, T-bolt, wing screw, hanger bolt, spherical washer, tab washer, threaded insert, weld nut, clip nut, pipe elbow, pipe tee, hose barb, hex tube, barrel nut, timing pulley, jaw coupling, muff coupling, handwheel, V-block, threaded rod, round standoff, D-shaft, keyed shaft, split collar, flange bolt, double-end stud, weld stud, jam nut, rivet nut, square washer, countersunk washer, pipe cross, pipe cap, concentric reducer, star knob, ball knob, crank handle, Oldham hub, flanged coupling, shaft support, leveling foot, pipe plug, eccentric, or slip-on flange. Newer shop bases (reducing elbow through C-channel and earlier batches) are listed on /parts; do not treat that catalog as a mesh dataset. Helical/bevel/worm gears, nyloc/lock nuts, Phillips machine screws, pop/blind rivets, 45° elbows, Heli-Coil inserts, and assemblies are refused. External ISO threads on a cylinder, hex-bolt/SHCS/button/CSK/carriage/pan-head/cheese-head/slotted-countersunk/round-head/set-screw/eye-bolt/thumb-screw/lag-screw/J-bolt/T-bolt/wing-screw/hanger-bolt shank, hook-bolt shank, shoulder-screw thread, or U-bolt legs are modeled; an Acme/trapezoidal rod is its own solid (not ISO 60°). Holes are drill or tap-drill size (no internal thread). Printability is a watertight-mesh check, an estimated min wall (0.8 mm threshold), and a 45° overhang check on the mesh (build-plate faces ignored; overhangs warn, they do not fail the build). Shop drawings export as R2010 DXF and AutoCAD R2000 DWG. - Text to CAD (home): https://aicadbot.com/ - Text to STL for 3D printing: https://aicadbot.com/text-to-stl - Text to STEP for CAD editing: https://aicadbot.com/text-to-step - Text to DXF 3-view drawing: https://aicadbot.com/text-to-dxf - Text to DWG AutoCAD drawing: https://aicadbot.com/text-to-dwg - Parts catalog (compiler name map, not a mesh dataset): https://aicadbot.com/parts - What is text to CAD: https://aicadbot.com/guides/what-is-text-to-cad - Text to CAD vs traditional CAD: https://aicadbot.com/guides/text-to-cad-vs-traditional - Compiler facts (coverage, refusals, drawings): https://aicadbot.com/guides/compiler - Compiled CAD vs AI mesh: https://aicadbot.com/guides/text-to-cad-vs-ai-mesh - Pricing: https://aicadbot.com/pricing
