# QSteelCAD: Light Gauge Steel and Cold Formed Framing Software

Light gauge steel software: QSteelCAD builds wall panels and roofs from a DXF plan, checks rivet holes, lengths and clashes, and writes rollforming files.

CAD/CAM software for light steel, prefab, modular and hangar manufacturers. It builds panels and the roof from your DXF plan and writes every profile to your rollforming machine's file.

## Everything on one platform

One model from plan to presentation, with no redrawing.

- [Create architecture from plan](https://qsteelcad.com/en/solutions/plan-to-architecture): Walls, doors and windows in a DXF plan are recognised; in three steps wall panels are built with studs, lintels and bracing.
- [Automatic roof](https://qsteelcad.com/en/solutions/automatic-roof): Builds hip, gable or mixed roofs with trusses, ceiling and roof panels in one window.
- [Production and CAM](https://qsteelcad.com/en/solutions/production-and-cam): Every profile is written with its length, holes and notches to the .bde file your rollforming machine reads.
- [Presentation and costing](https://qsteelcad.com/en/solutions/presentation-and-costing): Renders with cladding, rooms and furniture; quantities, cost, rivet and screw counts from the same model.

## For everyone on your team

One model gives each team its own output.

- **Management and purchasing:** Takeoff, cost, rivet and screw counts come from the same model as CSV.
- **Engineering:** Sections and bracing stay your decision; the program flags joints that need approval.
- **Production:** Every profile goes to the line as a .bde line, after an error check.
- **Sales and architecture:** Render, interiors and furniture for client presentations from the same model.

## Why QSteelCAD

QSteelCAD is developed by a team that knows the design and production of light steel buildings closely. Every feature closes a gap between the drawing and the line.

- **Turkish and English:** Every command also has its English name; your team works in both.
- **One model, one file:** Plan, panels, roof, presentation and production file in the same model.
- **Lines your machine can run:** Operations your machine profile doesn't support never reach the line.
- **Engineer approval flags:** The program tells you which joints need an engineer's approval.
- **No invented costs:** If a material has no price, it says “enter price”.
- **Safe updates:** Licence, settings and projects are kept in every release.

## QSteelCAD is a RENMAE product

RENMAE is a technology company bringing software, artificial intelligence, engineering and automation together in one production process.

The team knows the design, engineering and production of light steel and prefab buildings closely. QSteelCAD grew out of that experience and is RENMAE's first main product.

## Frequently asked questions

### Which files can I open?

DXF floor plans, including binary DXF, MLINE, ELLIPSE, SPLINE and dynamic blocks. The program does not read DWG; save the file as DXF in AutoCAD and open it.

### Which rollforming machines does it work with?

The program writes production files for rollforming lines that read .bde lines. Rollform-80, 90, 140, 200 and 300 profiles come ready, and stations switch on or off per profile. Let's check your machine's line format together in a meeting.

### Does it do structural calculations?

QSteelCAD runs production checks: error check, minimum length, clashes and model audit. It also flags joints that need an engineer's approval. Structural adequacy, including bracing and section choices, is for the project engineer to approve.

### Do I need a separate program for presentations?

Renders with cladding, roof cover, rooms and furniture come from the same model, and quantities and cost export as CSV. Save images as PNG, JPG or BMP and the model as GLB.

### How does licensing work?

The licence is activated online and tied to one computer. While the program is open the licence is checked regularly; it keeps running for 7 days without reaching the server. Get in touch for packages and pricing.

### Do updates affect my projects?

Updates keep your licence, settings and projects. Structures in older projects are recognised by newer versions, for example older double-collar K braces.

### Which Windows versions does it run on, and how long is setup?

It runs on Windows 10 and Windows 11. The setup wizard installs everything it needs; setup takes about a minute.
