Convert OBJ to SLDDRW

Understanding OBJ and SLDDRW file formats

OBJ is a widely used 3D geometry file format developed by Wavefront Technologies. It stores 3D models as a collection of vertices, faces, and texture coordinates, making it popular for 3D modeling, printing, and animation. SLDDRW is a proprietary drawing file format used by SOLIDWORKS, a leading CAD software. SLDDRW files contain 2D engineering drawings, annotations, and views generated from 3D models.

Why convert OBJ to SLDDRW?

Converting an OBJ file to SLDDRW is useful when you need to create detailed 2D engineering drawings from a 3D model for manufacturing, documentation, or sharing with engineers using SOLIDWORKS.

How to convert OBJ to SLDDRW

Direct conversion from OBJ to SLDDRW is not possible because OBJ is a 3D mesh format, while SLDDRW is a 2D drawing format. The process involves two main steps:

1. Import the OBJ file into SOLIDWORKS:
   • Open SOLIDWORKS.
   • Go to File → Open and select your OBJ file.
   • Follow the import wizard to bring the 3D mesh into SOLIDWORKS. You may need to convert the mesh to a solid or surface model using SOLIDWORKS tools.
2. Create a drawing from the imported model:
   • With the model open, go to File → Make Drawing from Part/Assembly.
   • Select a drawing template and place standard views (top, front, side) as needed.
   • Add dimensions, annotations, and other details.
   • Save the drawing as an SLDDRW file using File → Save As and choose SLDDRW as the format.

Best software for OBJ to SLDDRW conversion

The most reliable software for this conversion is SOLIDWORKS itself. It offers robust import tools for OBJ files and comprehensive drawing creation features. For best results, ensure you have the latest version of SOLIDWORKS and any necessary add-ins for mesh handling.

Tips for successful conversion

• OBJ files are mesh-based and may require conversion to solid bodies for detailed drawings.
• Clean up the mesh in a 3D editor (like Blender or MeshLab) before importing to SOLIDWORKS for smoother results.
• Use SOLIDWORKS' ScanTo3D add-in for advanced mesh-to-solid conversion if available.
