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.
