Generally, when doing electromagnetic simulation, you need to export the model to an STL file and save it. The STL file is a very common 3D model file. It usually uses triangulation. Yes, the STL file already contains the segmentation information. When exporting, Already meshed. So the question arises, line segments cannot be divided into triangles, so if there is a line segment in the model, how to save this line segment into the 3D model file? The STEP format shows a great effect!
STEP (Standard for the Exchange of Product model data) is a standard format for the exchange and sharing of 3D CAD models. To convert some spatial line segments into STEP files, you can follow the steps below:
1. Make sure the CAD software you use supports exporting STEP format files, such as SolidWorks, AutoCAD, CATIA, etc.
⒉Draw a space line segment and ensure that the endpoints of the line segment have closed geometric shapes, otherwise errors will appear in the exported STEP file.
3. Select the export file format as STEP format and save the file.
4. When saving the file, you can set the version and options of the STEP file. When setting options, you need to pay attention to selecting the correct unit and precision to ensure that the exported STEP file meets the requirements.
5. After the export is completed, you can use software that supports STEP format to open the file for viewing and editing.
