How to get a cutting plan and an order from your rebar drawings, step by step.

Last updated: 5 November 2026

What Rebarcut does

Rebarcut takes the rebar tables from your drawings (bar mark, diameter Ø, pieces, length) and works out the cutting plan: how many bars of each diameter and length you need, and how to cut each one so you buy the least steel. From the same cutting plan you create the supplier order and the PDF for the yard. If you have bars in stock, they are used first.

Quick start

Everything happens on one page: “New cutting plan”, the first item in the menu on the left. The app opens there when you sign in.

  1. Choose or create the project

    In “Project”, pick a project or “+ New project…” and type a name.

    “Structure (optional)” only groups your drawings, for example “K418 foundation”. If you do not need it, leave it as it is.

  2. Upload the PDF drawings

    Drop one or more PDFs on the box or tap to choose them (up to 10 MB each).

    The AI reads the rebar tables. This usually takes 1–3 minutes. Meanwhile you can upload more drawings or check the ones that are ready.

    No PDF? Use “Type rows or import Excel / CSV”.

  3. Check the rows

    Each table shows its rows: Mark, Ø, Pieces, Length (m). Press “View drawing” and compare every row with the drawing.

    Fix anything directly in the row. You can also use “Add row” and “Delete row”.

    The bar shape next to the mark can be clicked: it opens “Bar shape”, where you correct the dimensions of each part.

    Rows with a problem are marked in red, and the message under the table says what is wrong. Fix them before you calculate.

    Only ticked tables go into the cutting plan. Changes are saved with “Save changes”, or automatically when you calculate.

  4. Calculate the cutting plan

    Press “Calculate cutting plan”. Bars are cut from the project’s production lengths with the least waste.

    If you have bars in stock, first tick “Use bars from my stock first”. Bars and offcuts in the warehouse are used before new bars.

  5. Read the result

    The result is grouped by diameter. For each Ø you see how many bars of each length you need and how each one is cut: which marks come out of each bar.

    Anything left over up to and including 0.50 m is scrap. Anything longer is an offcut: it goes back to the warehouse, is listed separately (“Offcuts to stock”) and does not count as waste.

    When the tables come from several drawings, each mark gets the table’s letter in front (A-, B-…).

  6. Download the PDF for the yard

    Press “Cutting plan PDF”. It is the cut list for the yard and reads well on a phone too.

    “Open full cutting plan” opens the cutting plan’s page. There, under “Detailed table (row by row)”, you see every mark separately.

  7. Create the order

    Press “Create order”. The order already lists the bars per diameter and length, for example Ø16 / 12 m.

    You enter the “Order weight” of each line yourself, looking at the cutting plan, and press “Save order”. “Download PDF” gives you the file for the supplier.

    If the cutting plan uses your warehouse, the warehouse is updated when you save the order.

How it is organised

Everything you create in “New cutting plan” is stored in this order. You also find it in the menu on the left, under “Projects”.

  1. Project
  2. Structure
  3. Drawing
  4. Rebar table
  5. Cutting plan
  6. Order
Project
The job or site. It holds the cutting settings. Menu: “Projects” → click the project’s name for its settings, or “New project”.
Structure
An optional group of drawings inside the project, for example “K418 foundation”. It can have its own warehouse. Menu: under the project, “Structures”.
Drawing
The PDF you uploaded. Menu: under the structure, “Drawings”.
Rebar table
The rows read from a drawing (mark, Ø, pieces, length, shape). A drawing can have more than one. Menu: under the project, “Rebar tables”.
Cutting plan
The result of the calculation for one or more tables. Menu: under the project, “Optimization plans”.
Order
The supplier order made from a cutting plan. Menu: under the project, “Orders”.

“Warehouses” is in the same part of the menu, above “Projects”.

Codes

Projects, structures and drawings each have a short code, for example XALKD for the project, K218 for the structure and FOUND for the drawing. The codes of rebar tables, cutting plans and orders are built from them automatically.

Rebar table
PLN-XALKD-K218-FOUND-01
Cutting plan
PLN-XALKD-K218-OPT-01. When its tables come from several structures, without the structure: PLN-XALKD-OPT-01.
Order
ORD-XALKD-K218-BAS-01, following its cutting plan’s code.
  • Type the short code in the project form (“Project code”), the structure form (“Structure code”) or the drawing form (“Drawing short code”).
  • Leave it empty and we make one from the name: project “Παράκαμψη Χαλκίδας” (Halkida bypass) → PARXA, structure “K218 foundation” → K218. A drawing takes the sheet number from its code, e.g. 60420, if it has one.
  • Greek letters are written in Latin, so Κ218 and K218 are the same code whichever keyboard you type it on.
  • The number at the end (01, 02…) counts separately for each combination.
  • If you change a short code, it applies to what you create from then on. Existing records keep their codes, as do those created before 5 November 2026 (e.g. RS012).

Project settings

Open them from the menu: “Projects” → the project’s name. Changes apply to the next cutting plans; plans already calculated stay as they are.

Production lengths
The bar lengths your supplier delivers. In Greece: 12, 13.50 and 14 m; tick the ones you can get. A project created from “New cutting plan” starts with 12 and 13.50 m. The calculation picks the mix that needs the least steel.
Special length
Optional, for example 11.70 m. If you enter it, bars are cut only from it, not from the production lengths. A piece longer than it is flagged as an error.
Max transfer load, Tonnage bundles weighing
Truck details. They are stored now for orders sized to the truck, which come later. Today they do not change the cutting plan.

Warehouse

The warehouse holds the steel you already have: straight bars and offcuts from earlier cuts.

  • Create one: menu “Warehouses” → “New warehouse”, or from a structure’s form (“New warehouse”).
  • Bars: in “Bar stock” enter the diameter, length and quantity, with type “Straight”. Only rows ticked “Used for optimization” are used for cutting.
  • Offcuts: leftovers longer than 0.50 m from a cutting plan calculated with a warehouse are added to it automatically.
  • Using it: in step 4 tick “Use bars from my stock first” and, if you have several warehouses, choose one. Its bars and offcuts are used before new bars.
  • Updates: not when you calculate, but when you save the order. Then the bars used are taken out and the new offcuts are added, once.
  • If the warehouse covers everything, there is nothing to order: press “Confirm stock use” on the result to update the warehouse.
  • If the warehouse changed in the meantime (for example another cutting plan took the same bars), what is left is used and you see a warning. Check the warehouse then.

Recycle bin

Nothing you delete is lost: it goes to the “Recycle bin”, at the bottom of the menu on the left, and stays there for as long as you want.

  • This covers projects, structures, drawings, rebar tables, cutting plans, orders and warehouses.
  • To bring something back, click “Restore” on its row. The most recently deleted items come first.
  • When you delete a project or a drawing, everything under it is hidden too. Restoring it brings them all back.
  • If you restore something whose project or drawing was deleted, those come back as well, so you find it in its place again.
  • Deleting and restoring never change the warehouse stock.

Cutting rules

  • Least steel: for each diameter, the cutting plan needs the least new steel. Pieces from different marks and different tables can come out of the same bar.
  • Scrap and offcuts: anything left over up to and including 0.50 m is scrap. Longer leftovers are offcuts and go back to the warehouse.
  • Special length: if the project has one, bars are cut only from it.
  • Variable-length bars (for example “7.24÷1.12”, or with a length table) are cut at their average length, as the drawing’s table lists it.
  • A piece longer than every available bar is never dropped: the row is flagged (“longer than the longest bar”) so you can check it against the drawing or change the production lengths.
  • Bending elongation (stirrups, L and U bars) is not added: the table length is cut.
  • Pile spirals («ΣØ») appear in the table marked “Spiral · not cut”. They are not cut from 12/14 m bars and go on the order as their own line (e.g. “Φ14 spiral, 4 × 434.55 m”). If the AI misses one, click “Is it a pile spiral (not cut)?” on the row flagged as longer than the longest bar.
  • Lengths are handled in whole millimetres, so there are no rounding errors.

Tips for better PDF reading

  • PDFs exported straight from the design software (export or print to PDF) give the best results: their letters and numbers are text, not pictures.
  • Simple piece lists are read too, such as «ΚΟΜΜΑΤΙΑ» with lengths in cm.
  • Scans and photos are read less reliably. If that is all you have, check every row carefully or type the table.
  • A drawing can have more than one rebar table: each table is shown separately.
  • Whatever you upload, always check the rows against the drawing before you calculate. The AI can misread a number.

Frequently asked questions

The AI missed a row. What do I do?

Press “Add row” in the table and type it. If rows were left out because a value could not be read, the message next to the drawing’s file lists the missing marks. If no table was found at all, type it or import it from Excel / CSV.

Can I change rows later?

Yes, in step 3 or from the menu under “Rebar tables”. Then calculate the cutting plan again. Cutting plans calculated before the change stay as they were.

Why is a row marked in red?

Something is missing or does not add up: the mark is missing, no diameter is chosen, the pieces are not a whole number above 0, the length is 0, or the piece is longer than the longest bar. The message under the table says which row and what is wrong.

I have several drawings with the same diameters. Do they go into one cutting plan?

Yes. Tick all the tables and press “Calculate cutting plan” once. Pieces from different tables share bars, so there is less waste. The letter in front of the mark (A-, B-…) shows which table it comes from.

Where do offcuts go?

If you calculated with “Use bars from my stock first”, they go into the warehouse when you save the order (or press “Confirm stock use”) and are used in later cutting plans. Without a warehouse, they are listed on the cutting plan so you can keep them in the yard.
