Import & Export
Import & Export Overview
Move models in and out of JW Slope.
JW Slope reads models from external tools and saves to its own native format. All file handling is local: imports are parsed in your browser and exports are written to files you download or save directly — nothing is uploaded to a server.
Supported paths
| Path | Direction | Format | Notes |
|---|---|---|---|
| Slide2 | Import and export | .slmd / .slim archive | Multi-scenario; geometry, materials, water, loads, and support. |
| DXF | Import only | .dxf | Geometry only; no DXF export. |
| Native project | Save and load | .jws | SQLite-based project file, with a .jwsr results sidecar. |
Choosing a path
- Coming from Rocscience Slide2? Use the Slide2 import. It extracts the full multi-scenario structure and most model entities, and can export back to a Slide2 archive that preserves that structure.
- Have a CAD drawing or a section cut from a 3D surface? Use DXF import to bring in geometry, then assign materials and add loads in JW Slope.
- Saving your own work? Use the native
.jwsformat. It stores the entire project — all groups and scenarios — and is the only format that round-trips a JW Slope model losslessly.
What does not import
Importers map only what JW Slope can represent faithfully. Unsupported entities are either skipped with a warning or, where misrepresentation would be dangerous, cause the import to be rejected. The most important case is Generalized Anisotropic materials in Slide2 files, which block the import rather than being silently approximated. See the individual import pages for the full list.
