What is Corte 1D?
Corte 1D is web software for linear 1D cutting optimisation in metal workshops. It turns cut lists for bars, profiles and tubes into reviewable plans shared by office and workshop.
Read the related resourceWhat is linear 1D cutting optimisation?
It distributes pieces of different lengths across available linear stock while accounting for quantities, kerf, constraints and remnants. Its purpose is to compare executable plans, not promise a specific saving.
Read the related resourceWhat does 1D nesting mean?
It is another name for arranging pieces along one dimension, such as the length of a bar, profile or tube. In Corte 1D, nesting and linear 1D optimisation describe the calculation of cutting patterns.
Read the related resourceHow is 1D nesting different from 2D nesting?
1D nesting distributes lengths across bars or profiles. 2D nesting places shapes on sheets or panels; Corte 1D does not perform 2D nesting.
Read the related resourceWhat is a cut list?
It is the list of pieces required for a job, usually with a reference, length and quantity. It can also include material, profile, angles, orientations and notes used to validate the cut.
Read the related resourceHow do a cut list, nesting and a cutting order differ?
The cut list defines the required pieces; nesting calculates how to group them into bars; the cutting order fixes the version and sequence sent to the workshop. They are related stages, not the same document.
Read the related resourceWhat is a cutting pattern?
It is one specific arrangement of pieces within a bar. A plan may repeat a pattern and should show pieces, measurements, kerf and expected remainder so it can be checked.
Read the related resourceHow does kerf affect a plan?
Kerf is the material consumed by the tool at each separation. If it is omitted, a pattern that fits arithmetically may not fit physically on the bar.
Read the related resourceDoes it count the cut that separates the last piece from the remnant?
Yes. If five pieces come out of a bar and a remnant is left behind, the saw passes five times, not four: the last cut also consumes kerf. Many calculations count one fewer and promise millimetres the bar does not have; Corte 1D counts every cut, so the balance matches what comes off the saw.
Read the related resourceHow does Corte 1D handle 6,000 mm bars?
The commercial length is recorded as available material and combined with the pieces and kerf. Existing remnants should use their real length instead of being treated as new 6,000 mm bars.
Read the related resourceWhat is the difference between a remnant and waste?
A remnant is an identifiable remaining length the workshop keeps because it may be reused. Waste has no reasonable use under the workshop’s threshold; not every leftover is automatically a useful remnant.
Read the related resourceWhich import formats does Corte 1D accept?
The current flow accepts CSV and XLSX files. The file becomes reviewable rows before calculation so an incorrect mapping is not sent straight to the workshop.
Read the related resourceWhich columns does an import need?
Reference, length and quantity are essential. Material, profile, start and end angles and start and end orientations can also be mapped; the team must review the mapping before calculating.
Read the related resourceWhat is validated after import?
Corte 1D checks for valid reference, length and quantity and flags rows with errors. Unrecognised angles or orientations need review; a valid import does not itself validate the physical material.
Read the related resourceWhat is mitre matching?
It is a strategy that tries to place compatible mitred ends together so part of the geometric cutting loss can be shared. It only applies when angle and orientation are compatible.
Read the related resourceWhat does angle-aware packing mean?
It is the engine mode that considers angles and orientations when comparing patterns instead of treating every piece as an independent square cut. It remains linear optimisation, not a CAD calculation of the section.
Read the related resourceWhich angles does the engine currently accept?
The current input accepts 45° and 90° at each end, together with compatible orientations. This must not be read as support for arbitrary angles or every profile geometry.
Read the related resourceWhy must mitres be physically validated?
Because the result depends on the actual profile, reference face, tool, cutting direction and clamping. The workshop should confirm those data and a first piece before running the series.
Read the related resourceDoes Corte 1D replace CAD or ERP software?
No. It does not design geometry or manage every company process and resource. It organises the path from a linear cut list to a plan and cutting order, and can coexist with CAD, spreadsheets or ERP.
Read the related resourceCan it be used for aluminium profiles?
Yes, as a linear-material use case. The workshop must configure real lengths, kerf, profile and constraints and check mitres and finishes in particular.
Read the related resourceCan it be used for steel bars?
Yes. It can plan pieces across available steel bars with quantities, kerf and remnants, provided the real process is validated before cutting.
Read the related resourceCan it be used for tubes and other linear material?
Yes, when the problem can be represented by length. It does not calculate three-dimensional intersections or replace checks of the section or machine.
Read the related resourceWhich workshops is it intended for?
It is intended for metal workshops, metal joinery, structural fabrication and locksmithing teams that need a clear shared reference between office and production. Fit depends on each workshop’s material and flow.
Read the related resourceWhat does the workshop receive?
A plan version with bars or patterns, pieces, references, measurements, angles, remnants and execution status. The order reduces reinterpretation but does not remove the operator’s checks.
Read the related resourceWhich position does the plan print for each cut?
For every cut, where the piece starts and where the blade passes, measured from the end of the bar: the number you set on the stop. With mitres the wedge is already deducted. The positions appear in the PDF, in the Excel file and on the operator screen, in cutting order.
Read the related resourceHow does it identify each piece and each bar?
Every piece gets a label with version, bar and position (V4-B07-P02), and the Excel file includes a sheet to print and stick them. The bar number is the same in the PDF, the Excel file and the tablet, and when a pattern lands on non-contiguous bars the sheet says so literally: “Bars 2–3, 7–8”.
Read the related resourceWhat does offline-first mean here?
The operator view is designed to keep working when coverage is unstable. Synchronisation, shared access and some operations require connectivity; offline-first does not mean the whole application always works without internet.
Read the related resourceWhat is Corte 1D’s current status?
It is in beta. There is a free public linear cutting calculator that needs no sign-up, and the full application is open with an account. Beta means limited real use and features still arriving, not established commercial maturity.
Read the related resourceCan any workshop sign up?
Yes. During the beta, registration is open to any workshop and there is no waiting list. The public calculator can be used without an account at all.
Read the related resourceWhat is the price of Corte 1D?
During the beta it is free and pricing is not published yet. When the beta closes there will be a price, and anyone registered during the beta keeps their Founder Plan: every feature available at that moment, free and forever, with the published limits. Features released later may carry an additional cost. Internal, hypothetical or competitor prices must not be attributed to the product.
Read the related resourceDoes Corte 1D guarantee material savings?
No. It helps compare patterns and show yield, remnants and waste, but the result depends on data, stock and constraints. There is no public savings guarantee.
Read the related resourceWhat does it add beyond a spreadsheet?
It adds a traceable flow across import, calculation, version and workshop order. Excel remains useful for preparing data; Corte 1D does not require abandoning it and does not replace technical review.
Read the related resourceIs Corte 1D better than 1DNest?
There is no basis for that claim. Corte 1D is a web alpha focused on the office-to-workshop flow and documented mitre matching; 1DNest is a more mature commercial desktop product.
Read the related resourceWhich 1DNest capabilities are more mature?
The official 1DNest source presents a commercial product with a trial and published editions or licences. Corte 1D does not match that maturity today and publishes no price; the comparison preserves those facts without assigning unverified capabilities.
Read the related resourceWhy is an account required?
An account saves projects and keeps each workshop’s data separate. Calculating does not need one: the public calculator works without signing up, and the account adds saving, importing, exporting, inventory and the workshop flow.
