Export simulation result as model
Application area:
The simulation result shown on the Simulation page can be saved to a file and later reused as a workpiece in another project, or, for the STL format, in third-party software. This carries the machined state of a part from one project into the next, so machining continues from the already-processed stock.
Typical scenarios:
Splitting a long machining job into several projects and passing the intermediate stock between them.
Reusing the exact machined model as the workpiece for a follow-up setup without loss of detail.
Handing the simulated stock to external CAM/CAD software through a neutral mesh format.
Saving the simulation result.
Two entry points are available. Both open the Save As dialog.
Context menu on the Simulation page. Right-click in the simulation window and choose Save simulation result.
Main menu. Open the Save menu (disk icon in the top-left toolbar) and, under Export, choose Simulation result.
In the Save As dialog, enter a file name and select the format in the Save as type drop-down:
Simulation result, precise (*.camsr). Selected by default.
Simulation result, STL with losses (*.stl).
File formats.
Simulation result, precise (*.camsr)
The native simulation format. It stores the exact simulation model as computed, with no conversion.
No loss of precision. The model is preserved as-is; when imported back as a workpiece it is used directly, without any approximation step.
Recommended whenever the file is reused inside the CAM system. This is the default option.
Simulation result, STL with losses (*.stl)
The standard STL triangle mesh.
Universal. Opens in most CAM/CAD applications and any tool that reads STL.
Lossy. The precise model is converted to a triangle mesh on export; on re-import it is loaded as a mesh and re-processed, so the reused stock is an approximation of the original rather than the exact model.
Reusing a saved result as a workpiece.
A *.camsr file can be loaded back into another project as the workpiece:
Go to the Workpiece tab on the Machining page.
Click the Sim result button.
Select the *.camsr file.
The exact machined model is added as the workpiece, and machining can continue from it — no re‑voxelization, no detail loss.
Note
The *.camsr file records the measurement units it was saved in. If you import a result whose units differ from the current project's, the import is canceled, because automatic unit conversion (mm ↔ inch) is not supported yet. Save and reuse results within the same unit system.
