Constraint-based 2D CAD
The part profile is drawn right here: line, arc and dimension, with real constraints. Change one dimension and the whole drawing adjusts — with no license for any other program.
From the part drawing to the
program that runs on the machine
You draw the part or import the 3D. It flattens it, finds the bend sequence that doesn't collide, shows the part moving inside the machine and delivers the program ready for your controller — with the bend already corrected for your press brake.

Five steps between the idea and the bent sheet
It's not five programs. It's one, and each step already knows what the previous one decided — the tool you chose comes back in the report, and your controller's math comes back in the dimension that goes to the machine.
- 01
Draw
Draw the part, or import the 3D and DXF you already have.
- 02
Flatten
K-factor, radius and thickness — the developed length comes out instantly.
- 03
Tool up
Punch, die and material from your own library.
- 04
Simulate
It finds the bend sequence that doesn't collide — and shows where it would.
- 05
Export
Controller program, production report and cutting DXF.
What sets it apart No CAD needed to draw the part.
No CAD needed to draw the part.
It comes with one.
Most bending programs expect the drawing ready, made in some other software. NiaBend has its own constraint-based CAD: you draw the part's 2D profile on its screen, lock the dimensions that matter and move on to the flat pattern, the tooling and the simulation — without opening any other program.
- The 2D profile is drawn right here
- Line, arc and dimension, right on NiaBend's screen. You draw the part's cross-section — every flange, every bend, every radius — and the developed length is recalculated as you sketch. No other program to open, no other program's license to pay for.
- With constraints, like a real CAD
- Horizontal, vertical, parallel, perpendicular, angle, length, radius, tangent, symmetry. You lock what matters; change one dimension and the whole drawing adjusts, with nothing out of place.

Nine modules, one program
From the first line to the folder on the server — all in the same program, running on your shop's computers.
Bend simulation
Before it goes to the machine, you watch the part travel through it: punch, die, die holder, beams, back gauge fingers and the throat. If it's going to hit, it tells you where.
Drawing and flat pattern
The profile becomes the blank for cutting. The flat pattern comes out as DXF with the bend lines marked — marked, not cut.
STEP part import
The 3D your customer sent comes in as a sheet metal part: it recognizes every bend — angle, direction and radius — and flattens it instantly. From there the part goes to the simulation like any other.
Export the file ready for your machine
The bend math changes from controller to controller. NiaBend uses ESA's or NiaBend 1.0's, depending on the machine — and the file comes out in the format that controller expects, with no conversion in between.
Production report
Along with the program comes the report for whoever is going to bend: the bend sequence, the tool for each one, the dimensions and the estimated time.
Your tooling
Punch, multi-V die, die holder and materials, each with its real drawing. The tool used is stored inside the part, exactly as it was that day.
Your machines
Every press brake on your floor registered as it really is: axes, beams, throat and back gauges. What your controller doesn't have disappears from the screen.
Work with a server, without copying files
One shared folder on the server, and every computer opens the same archive of parts, tools and machines. Each one works on a local copy — the part opens even with the server down.
Calibration
It gets the bend right on your press brake, with a practical test
Two press brakes of the same model don't bend alike. Beam play, tool wear, the sheet from that batch — none of it is in any formula. Instead of guessing, NiaBend measures.
Once calibrated, the machine receives the dimension already corrected. You stop compensating in your head and remaking the first part.
- Bend a test part on your press brake, with the tool and material you'll actually use.
- Measure the angle you got and note what the controller was showing.
- Type both into NiaBend. It takes less than a minute.
- Done. It stores the difference and starts correcting the next bends on its own — on that machine, with that tool, in that material. The more tests you run, the finer the correction gets.
Compatibility tested byte by byte
Export the program straight to your machine, or export a report.
Compatible controllers
- ESA S840W
- Nia Bend 1.0
The program that comes out of here goes into the controller the way it expects it, with no conversion in between. And the machine parameters already in the controller can come to the computer, so you register it without typing everything again.

A report for any machine
If your machine's controller isn't compatible, you can export a PDF or HTML report with every axis position, bend by bend — the operator types it into the controller and the part comes out the same.

More controllers coming
We're adding new controllers to NiaBend. If you make press brake controllers and want to see yours here, get in touch: the integration is done together with the manufacturer and tested byte by byte before it joins the list.
Add my controllerWhat NiaBend doesn't do
It's on the sales page on purpose. It's cheaper for you to find out now than after installing.
The simulation doesn't replace checking
It works with what you registered. A mismeasured tool or a wrongly registered machine gives a pretty, false simulation — check the first part.
It doesn't read programs or tools from the controller
From your controller it brings only the machine parameters, to register it. The part programs and tools already in there aren't read.
