C3 — CADD300_Modern

Fuller geometry, drawn in C3 — vector equilibrium, closest-packed spheres, and the Tetra720 mark

The Tetra720 mark, arrayed 12× at 30° with POLAR COPY — each copy stays upright, which is why the name reads level all the way around. Its sibling POLAR COPY ROTATE turns each copy with the circle instead: bolt circles, gear teeth, spokes. Even our logo is C3 geometry — draw it once, one command arrays it, one Cmd+Z removes the whole array

This eleven-room plan started as an iPhone walk-through of a 125-year-old apartment. The C3 Room Scanner (included with every C3) captured the walls; C3 imported them as native double-line walls, squared them to the grid, and aligned the scan seams. Then the finish work, all first-class C3 tools: doors re-hinged with FLIP HINGE and called out with DOOR DIM at their true widths, rooms tagged and measured by Auto Area, the schedule extracted, datum stations run down both sides, interior dimensions in every room, north arrow and scale bar to complete the sheet. The provenance note prints with the plan — capture date, cleanup report, and a reminder to field-verify. From front door to finished drawing in record time — because the big operations are single clicks: fill every wall cavity, flip a door’s hinge, measure a room, extract the schedule

The same apartment, before the drawing — this is the raw 3D model straight off the phone. Walk through with an iPhone and the C3 Room Scanner (included with every C3) captures walls, windows, and doorways with LiDAR; the blocks are furniture the scanner saw along the way. You keep this model — rotatable and zoomable in QuickLook — and C3 turns it into the fully dimensioned floor plan above. This is exactly the technology those scan-your-room apps advertise — except yours comes with a full CAD system attached. Their auto-dimensioning makes a picture; C3's Auto Dimension lands real dimensions — every room's interior clears, a DOOR callout on every door, envelope dims — that re-measure when you move a wall and undo in one step. And everything it places is an ordinary CAD object — grab any dimension, callout, tag, or note and move it, edit it, or flip the door it points at

Frame one, zero hand edits — a single office scanned on an iPhone, opened in C3 through the Files menu you see right there. Before the first click, C3 had already squared the scan (it arrived 19.4° off), trued four walls to 90°, joined the corners, placed the window and both passages, dimensioned the room in feet and inches, framed the view, switched off the grid, and grouped the whole import so it moves as one object. The note on the sheet is the import’s own receipt — every cleanup it performed, in writing

The same file, finished with ordinary C3 tools: one click filled every wall cavity, one click tagged the room with its computed area (141.0 SF), a door was hung directly in the scanned opening — the hinge lands at whichever jamb you click nearer — and datum ordinate dimensions run from a shared corner along both edges, the way machinists and framers expect. The Attribute Extraction table on the right reads the room tag as data: name and square footage, ready to become a schedule. Every element on this sheet is a live CAD object — move it, edit it, and the drawing stays true

Text to Outlines — type in any font installed on your Mac, pick it, one click: the true letterforms become real vector polygons, traced analytically from the font's own bezier curves to a 0.001″ tolerance, with the holes in every O, B, and A carried as proper inner paths a cutter understands. The big Didot outline is the proof — hairline serifs and razor-thin counters, faithfully traced. Letters arrive grouped as one object, and one undo restores the editable text. Export SVG with real inch units (Cricut-proven) or DXF, and cut: laser cutters, vinyl cutters, CNC routers, plasma tables, waterjets, engravers. Or export EPS and hand the screen printer vector art at exactly its drawn size. Sign makers and fabricators get filled letterforms; stick text remains the single-stroke engraving answer — between them, text leaves C3 ready for any machine

Exact-mathematics geometry — hatched gear profile, diameter callouts, and a six-hole polar array (one Cmd+Z removes the whole array)

Production drawings: dimensions with witness lines, hole callouts, hatched section views, and title blocks

Bearing & Distance annotation — click any line and it labels itself in surveyor notation: quadrant bearing in degrees-minutes-seconds plus distance, rotated to read along the line. The language of land surveyors, civil site planners, and plat drafters — and every distance field in C3 also accepts 12'6" architectural input directly

A complete parcel exhibit: four courses in metes-and-bounds notation, then one click inside with Auto Area — the boundary is detected from plain lines and the label lands at the centroid with exact area, acreage computed automatically, and perimeter. Site plans, plats, easement exhibits, deed sketches — drawn, closed, and quantified in one tool

Stationing — click an alignment and it stations itself: 0+00 through 10+00, ticks and labels riding the path around every corner. Then one more click inside for the exact area with acreage. The drawing's own caption says it: two clicks, done. Roadway exhibits, utility runs, and site boundaries in the language civil reviewers expect

Hole Table — click the part's datum corner, click Add All Circles, done: every hole tagged in shop convention (same-diameter holes share a letter) and a TAG / X / Y / Ø table measured from the datum. Machine shops, sheet-metal fabricators, and CNC programmers read this every day — the table exports straight to CSV

Line & Curve Tables — click each course and the plat annotates itself: L and C tags on the geometry, a Line Table of bearings and distances, and a Curve Table with radius, delta, arc, and chord from exact arc math. Then one click inside with Auto Area measures the whole parcel — curved boundaries and all, exactly. The subdivision-plat and roadway-exhibit standard, straight out of the Dimension menu

Weld & surface-finish symbols — not clip art, but parametric annotations built to AWS convention: pick fillet, groove, plug, spot, or seam; set the size, length-pitch, all-around, field-weld flag, and tail spec; then click the joint and the elbow. The finish mark's vee lands exactly on the surface, roughness value in place. Fabrication drawings for weldments and machined parts, annotated the way the shop floor reads them

GD&T — full ASME Y14.5 geometric tolerancing from the Dimension menu: feature control frames with all 14 characteristic symbols, Ø zones, Ⓜ/Ⓛ material modifiers, and up to three datum references; datum feature symbols that auto-advance A→B→C; and the frames know the rules — form tolerances refuse datums, as the standard requires. Around them, the mechanical staples: center marks on every hole, centerlines through the hole row, 4X/2X pattern callouts composed with their tolerances. This sheet reproduces a professional GD&T training example end to end — face, pin, and slot datums qualified in fixturing order, hole patterns positioned at MMC, profile on the outline, ordinates from the datum origin. Aerospace, automotive, medical-device, and job-shop drawings speak this language — now C3 does too

An architectural floor plan in a few clicks — WALL draws true double-line walls, DOOR and WINDOW cut themselves in with swings and glazing, FILL ALL WALLS hatches every wall cavity in one click (and FILL WINDOWS colors the glass), room tags measure their own rooms with Auto Area, and Extract Attributes builds the room schedule automatically. The caption in the revision cloud tells the story — and yes, the revision cloud is a C3 tool too

HVAC duct runs — click the centerline, get the double-line duct: corners become true tangent-arc elbows (dimension one and the radii measure exact — R6 inner, R18 outer on this 8″ run), size labels ride every straight section, and TEE BRANCH opens the main run into a branch with a genuinely open junction — the proof is the hatch, flowing uninterrupted from trunk to branch. Ended a run long? TRIM END takes it back in two clicks. Mechanical building services, sheet-metal shops, and anyone who's ever drawn ductwork line by line by line

The John Hardy MPC-1 preamp schematic with the color-coded Edit menu — every tool one click away

Layout / Paperspace — six viewports at different scales on a single sheet, with per-viewport layer groups

Photographs live inside drawings — schematic and product shots on one canvas, with move, resize, and crop handles

Block Attributes — 23 labeled LEDs extracted into three live documents: a schedule, a designator BOM, and a one-line parts list. The status bar tells the rest: this drawing survived a DXF round-trip

One click after importing a SparkFun RedBoard from Eagle: every component inventoried — designators, values, packages, from the ATMEGA328P down to the four status LEDs. A 24,857-primitive board file C3 had never seen, and its parts list was two clicks away. The table scrolls on canvas, exports to CSV, and the × dismisses it while you work

Multi-layer PCB on the dark canvas — 256 layers with one-click view settings

Gerber RS-274X + Excellon export — board setup, layer mapping, one-click fabrication output

A 1986 CADD/300 speaker design, reopened and re-hatched in C3 forty years later — your old drawings still work
