Prompt to steel.
Sketch to NC1.
Detailing software for steel fabricators. Describe a part, sketch it, or bring the customer's file, and get back the solid, the shop drawing and the NC1. It runs offline and keeps your work in your shop.

— The loop
Five ways in. One package out.
However the work arrives, an email, a napkin, a customer's old files, it leaves as a part your machines and your crew can run.
Prompt
Type it the way you would say it. “PL 1/2 × 24 × 20, two Ø13/16 holes” becomes an exact solid.
Sketch
Draw the profile in the full-screen sketcher. A closed loop becomes a plate part.
DXF
Drop in the customer’s DXF. Geometry comes through exact and round-trips back out.
PDF
Calibrate a vector PDF with two picks and one true distance, then trace real geometry. No AI guessing at your dimensions.
3D model
Open a STEP, or build parametric in the MODEL workspace: sketches, constraints, features, rolled members.
The package
STEP solid, shop drawing (PDF), NC1 / DSTV, DXF and a cut list. Every intake lands here: no re-drawing, no re-typing, no second tool.
Pick a prompt. This replays files the engine already wrote.

Drag to orbit. Assembly demo. This frame exported one STEP and one NC1 per member.
— The MODEL workspace
Parametric 3D that speaks steel.
A history-tree modeler with constrained sketches, extrude, revolve, fillet, chamfer, mirror and patterns, plus rolled steel members as first-class geometry, placed on work lines by AISC designation.
Members by designation
A portal frame placed on sketched work lines by AISC designation. One batch, one undo step.
Constrained sketching
Dimensions drive geometry, and the status bar says how many degrees of freedom remain: here, 3.
Drawings from the model.
The sheet is laid out from the solid: top, front, right and iso views in third-angle projection, overall dimensions, and a title block with the tolerances you would write yourself.
Mass comes from true volume, not a table lookup: 916.66 cu in, 260.0 lb for BM-101.
— Open it yourself
The files, not a picture of the files.
Every file below was written by the engine and copied here unedited. Drop the NC1 into Tekla, SDS/2, or your burn-table software; open the STEP in any CAD.
Holes and scribe lines in the model land in the NC1 as BO and PU rows at exact positions, written by the same verified writer that handles every part. Members export one NC1 each: the profile matches the designation and the length matches the work line to 0.01 mm. Families DSTV can't represent honestly are skipped with a stated reason, never silently mangled.
NC1 profile families: W, M, S, HP, C, MC, L, WT, MT, ST, HSS, PIPE
IC-PL-012: PL 3/8 x 24 x 48, one 13/16 hole, two scribe lines

Loading NC1 ...— The 2D sketcher
Draw a closed profile. Get a real part.
The full-screen SketchPad works the way your hands already know: window and crossing selection, osnap with per-kind toggles, typed dimensions while you draw, right-click to finish a run. Fractions are first-class input: 13/16 means Ø13/16″.
- Closed profile becomes an exact plate solid, shop drawing, NC1 and DXF
- Circles inside the profile are bolt holes, with no separate hole tool
- Trim, extend, fillet, mirror, offset, with typed distances
- DXF import and export that round-trips, proven by test
- Vector PDF import with two-pick calibration
— Built for fabricators
Why it holds up on the floor.
Runs offline
The geometry kernel runs on your machine. No internet on the shop computer? Modeling, drawings, and exports still work.
Your data stays in your shop
Parts, drawings, and your growing library live on your disk. Only license activation and the AI prompt-to-spec step talk to the Indolent server.
Exact math, detailer units
Millimeter-exact kernel inside, fractions at your fingertips outside: 1/16″ snap, feet-and-inches readouts, ± tolerances on the sheet.
Tested like it matters
Over 2,200 engine tests pin geometry to closed-form volumes and real file round-trips. A failing feature refuses honestly; it never ships a wrong part quietly.
