ArrayCalc
ArrayCalc is software by d&b audiotechnik. Auto-Calc-Pro is an independent tool and is not made, endorsed or supported by
d&b audiotechnik. It writes ordinary ArrayCalc project files (.dbpr), and new projects start from an empty
ArrayCalc project file included with the app.
Your files
Drawings and projects are opened in your browser and never uploaded. The AI advisor, when you use it, sends a geometry summary and a picture of the plan to Anthropic (with your own API key) or to the local model on your computer.
