CADdillo

CADdillo takes the two most common bottlenecks in small-scale drafting and removes both. The first is access: the editor, viewer and converter run entirely in a browser, need no installation, and cost nothing. The second is the blank-page problem. Instead of drawing walls from scratch, users describe what they need — 'three-bed, two-bath ranch, 1,450 sq ft, two-car garage' — and Dillo Bot asks a handful of clarifying questions before drawing a complete plan. The output is not a rendered image of a floor plan but live geometry: double-line walls with openings cut into them, door swings, windows, plumbing and kitchen fixtures, furniture, room labels with areas, and dimension strings, all placed from a library of 474 CAD blocks and distributed across named layers.

That distinction matters because everything downstream depends on it. Because the plan is real geometry, it can be moved, trimmed, re-dimensioned and extended with the editor's modify tools — move, copy, rotate, scale, mirror, stretch, array, trim, extend, break, join, offset, fillet, chamfer and explode — all snap-aware and undoable, with feet-and-inches dynamic input. Exports land in DWG, DXF or PDF and open in AutoCAD, BricsCAD, LibreCAD or DraftSight.

CADdillo also covers the less glamorous half of the job with a free converter: drop in a DWG (revisions r11 through r2018) or DXF and get a PDF back in around fifteen seconds, or DXF, PNG and SVG, with no watermark and no file-count limit. The block and template libraries are included at every tier, including the free one, and cover residential, commercial, industrial and MEP work — 95 MEP items across plumbing, conduit, HVAC duct and sprinkler systems, drawn double-line to size rather than as single-line schematics. Monetisation is deliberately pay-as-you-go: hand drawing, viewing, editing and converting never consume credits, and only AI work is metered.
