The following settings are recommended up to SolidWorks 2016 and Solid Edge ST 8
SolidWorks – System
SolidWorks - STEP Preprocessor
- To export a STEP file choose File -> Save as..., as file type choose STEP-Format (step, stp) and go to Options. A new dialog box appears.
- Under Output as the following options can be selected:
- Solid/Surface geometry: the geometry will be exported as solid and surface bodies. This is the recommended option.
- 3D curves: solid and surface bodies will be exported as wireframe entities and all 3D curves are also saved.
- Export sketch entities: export all the items in 3D curves, plus all 2D and 3D sketches in the document.
- Output coordinate system: by selecting default, no transformation matrix will be applied.
- Export face/edge properties: Exports face and edge properties. Clear this option to improve export performance.
- Split periodic faces: Splits periodic faces, such as cylindrical faces, into two. Splitting a periodic face can improve the quality of the export but can affect performance.
- An adjustment of the STEP file is not necessary.
Solid Edge - STEP Postprocessor
- To import a STEP file go to File -> Open, select the STEP file and go to Options. The Open File dialog box appears.
- These are the recommended options that must be selected:
- Generate Log File: to create a log file that contains warnings and information about the imported files. The name of the file is the .log and it is located in the same folder as the STEP file.
- Heal and Stitch: to heal and stitch the free surfaces to create a solid body. It is not required to specify a tolerance range.
- Simplify Geometry: replace the b-spline geometry from the model with simplified analytic geometry. This creates a smaller and more efficient model.
- In case of an assembly it is recommended to select the same Output Folder as the one where the imported *.asm file is going to be saved, otherwise the imported *.par files will be saved in the same folder as the STEP file.
- The New dialog box opens after choosing the STEP file. To import the model, a new part or assembly must be first created.
Solid Edge – System
- In case of an assembly a *.cfg file is created. This one contains the Display Configurations of the model.
