Models
A model in Dlubal CALC is a file you uploaded or one that came out of RFEM. What you can do with it depends on the format, and the difference that matters is whether a browser can draw it.
What opens in the 3D viewer
| Format | In the viewer |
|---|---|
.glb | Yes |
.ifc | Yes |
.dxf | Yes |
.stl | Yes |
.stp, .step | Yes |
.rf6, .rs9, .rsc | The preview, not the file itself |
A .rf6 is a Dlubal container and no browser reads one. What you see is the preview
geometry unpacked from inside it at upload. The file stays exactly as you uploaded it; the
viewer is looking at a rendering of it, not at the model.
Uploading
Drag the file into a chat, or add it in the Models panel. A geometry file is converted for display, a Dlubal model keeps its own bytes and gets a preview.
Example: you upload a 40 MB .ifc from the architect, ask what the spans are, and get
an answer about the geometry the file contains. The same question about a .rf6 answers
from the preview and the model data, not from a rendering of it.
What Dlubal CALC does with a model
The assistant reads what the file contains: geometry, member positions, and for a Dlubal model the structural data. It does not calculate inside the file. To build, calculate and read results in RFEM itself, connect RFEM and work against your open instance instead: Connecting RFEM.
