Cut Smarter.
Waste Less.
Build Faster.
Drop a KISS file. Get cut lists, plate nests, and a quotable proposal in seconds. Built for the estimator and nester at a small-to-mid steel shop.
— Before / after
Drag the divider.
Left: the cut list as it arrived, one part per stick. Right: the nest Forge computes. Both drawn from the same demo list in your browser.
Same 14 W12X26 parts. Same 40 ft sticks. Illustrative demo set; your yield depends on your cut list.
— Watch it nest
This is the whole job.
Fourteen beam cuts, first-fit decreasing onto 40′ sticks, drops called out — the same algorithm family the app runs on your real takeoffs, animated below with nothing mocked.

— Payback
What is a nest worth to your shop?
An estimate from three numbers you already know. Assumptions are stated; edit all of them in the full calculator.
Estimated payback, first year
1 days
Estimate. Yield defaults (40% to 58%) round a Forge 3.14.0-to-3.14.1 packer measurement on 163 real plate groups, not a hand-nesting baseline; 50% of nesting time saved is assumed. Edit every assumption in the full calculator.
Full calculator— Inside the app
Five nesters. One mode picker. Zero training.
Linear, plate, polygon, spreadsheet import, or a one-click KISS file straight from your detailing software. Pick the mode that matches your job — the rest is automatic.

Not a hosted SaaS. A real desktop app on your machine, $49.99 a year, cancel any time.
Drop a KISS file. Done.
Reads Tekla, SDS/2, and Advance Steel KISS output. Plates auto-route to the 2D nester. Bolts, nuts, washers auto-flag as buyouts.
Three nesters, one app
Length nesting (FFD/BFD with batch-yield optimizer). 2D plate nesting with shear-sequence planner. Polygon nesting from raw DXF.
Cut sheets that actually print
B&W-printable plate sheets with hatch patterns. Per-stick part-mark summaries. SHEAR SEQUENCE table on every plate. Helvetica + navy header bars.
Excel + PDF, no surprises
4-sheet Excel workbook (Summary, Buy List, Cut List, Yield). Proposal PDF with markup, scrap credit, and quote number. BOM grouped by material with AISC weights.
Slevin — offline AI that knows steel
No API key. No cloud. Slevin's entire knowledge base — 30+ reference documents covering AISC, ASME, API, AWS, OSHA, estimating, and proposals — ships inside the installer. Auto-detects W14X22, HSS6X6X1/4, and other section callouts and searches your steel-fab questions instantly.
Built for the estimator
No-login Simple Nesting view for quick quotes. Year-based quote numbers (YY-XXXX). Project save/load with version history. Ctrl+S, Ctrl+Z. Quotable proposals in seconds.
— How it works
Three steps. No training.
Drop the takeoff
KISS file from your detailing software, an Excel takeoff, or a CSV. Drag-and-drop into the app.
Pick your stock
Plate sizes auto-pick by yield. Linear stock uses your standard lengths plus any remnants in inventory.
Run the nest
Same-thickness plates share sheets. Dragon Plasma parts route to the 18'-6" table. Output: cut plan, BOM, proposal — in seconds.
