Dlubal CALC works inside RFEM

Through the Dlubal Connector, Dlubal CALC operates RFEM 6 and the Geo Zone Tool as an agent: it works out which steps a task needs, carries them out in sequence, and reads the results back. Build members and loads, change the model, run the check, and export the report, all from one dialog and on the licenses you already own.

Your licenses, your models,
one interface

If your office runs RFEM 6, RSECTION, or the Geo Zone Tool, Dlubal CALC connects through the Dlubal Connector, uses the licenses you already own, and works like an agent. Install it once beside your existing installation — no separate license and no change to your model files.

From then on, you can ask about the model you have open. CALC reads the live state, runs the check where it belongs, and reports back with the solver's numbers rather than an estimate. Every value carries its origin: calculated by the solver, calculated by a calculation skill, or answered by the language model.

RFEM 6 & RSECTION

Read the open model, review it for input errors, run design checks, and write results back — through the licenses already on your workstation.

Geo-Zone Tool

Name the project location and the site loads come back as EN 1991 load assumptions — snow, wind and seismic values calculated by the tool, not estimated by the AI, each with its zone and source stated in the report.

Drawings & models as they arrive

IFC, DXF, STEP, DSTV, STL, SDNF and GLB, plus PDF drawings and photos of hand sketches. Only the part you asked about is extracted.

Automate it, or build CALC into your own tools

The Dlubal API is what CALC itself calls when it drives RFEM. The same interface is open to you: generate an API key in your workspace, then run a check from your own application, batch a whole model set overnight, or file the PDF report straight into your DMS.
