Sometimes you want to reuse a part of the geometry of an already existing PLAXIS 3D model in a different model. With PLAXIS 3D it is possible to export the geometry from Input using the command __saveobjects. The volumes and surfaces from these objects can be easily imported into a newly created PLAXIS 3D project using the 
Import soil... and 
Import structures... options in Input.
The available formats of the exported files in PLAXIS 3D 2016 are:
- OpenCascade BRep files (*.brep)
- Standard for the Exchange of Product model files (*.step)
The command has the following structure:
__saveobjects"brep""C:\PLAXIS3D\Objects"
Parameters:
| __saveobjects | the command, note the double underscore |
| "brep" | file extension of the exported geometry file. In this case geometry.brep |
| "C:\PLAXIS3D\Objects" | directory of the saved objects |
The file geometry.<extenstion> exported in the specified directory include objects present in the Blue coloured tabs in PLAXIS Input program. These supported geometric objects created in Blue tabs (Soil / Structures) are:
- Surfaces and Polygons
- Volumes
- Soil volumes from boreholes
Note in PLAXIS 3D AE, PLAXIS 3D 2013 and earlier, only these were available (but are no longer supported in the latest version): Plaxis 3D Object files (*.px3o), Stereolithography files (*.stl) and Plaxis Mesh files (*.plxmesh). See the attached PDF document for details.
For more details on the __saveobjects-command or any other command, please refer to the Plaxis 3D Command Reference, available via the Help menu.
