Convert SLDDRW to STL

Understanding slddrw and stl file formats

SLDDRW is a drawing file format created by SolidWorks, a popular CAD (Computer-Aided Design) software. These files typically contain 2D engineering drawings, annotations, and layout information for parts or assemblies. STL (Stereolithography) is a widely used file format for 3D printing and computer-aided manufacturing. It represents 3D surface geometry using a mesh of triangles, making it ideal for rapid prototyping and 3D printing workflows.

Why convert slddrw to stl?

Converting slddrw to stl is necessary when you want to create a 3D printable model from a 2D drawing. However, it is important to note that slddrw files are 2D drawings, while stl files are 3D models. Direct conversion is not possible unless the drawing is linked to a 3D model. Typically, you must first open the associated 3D part or assembly file (such as SLDPRT or SLDASM) in SolidWorks and then export it as an STL file.

How to convert slddrw to stl

1. Open your slddrw file in SolidWorks.
2. Identify the referenced 3D part (SLDPRT) or assembly (SLDASM) file.
3. Open the 3D model file in SolidWorks.
4. Go to File → Save As.
5. In the Save as type dropdown, select STL (*.stl).
6. Click Options to adjust export settings (resolution, units, etc.), then click OK.
7. Click Save to export your 3D model as an STL file.

Best software for slddrw to stl conversion

The most reliable software for this conversion is SolidWorks itself, as it natively supports both file types and ensures accurate geometry translation. For users without SolidWorks, FreeCAD can import some SolidWorks files (mainly SLDPRT/SLDASM) and export to STL, but it does not support SLDDRW files directly.

Tips and considerations

• Always verify the 3D model before exporting to STL to ensure all features are present.
• Adjust STL export settings for optimal print quality and file size.
• If you only have the SLDDRW file and not the associated 3D model, you cannot create a true STL file for 3D printing.
