First, we need to know what STL and DWG files are. STL is the standard format used for 3D printing. Geometric information is stored in the form of triangles that make up a mesh. The file is created in any other 3D modeling software and it can be visualized in other 3D printing slicers like Simplify 3D or Cura.
On the other hand, we have DWG files which are basically the native file format of AutoCAD. It stores 2D and 3D vector image data and it’s highly compatible with other CAD software out there, which is why it’s one of the most commonly-used file formats in many industries. Check out our dedicated article if you want to learn more about this ubiquitous file type.
There are several ways to convert an STL to a DWG file, but one of the easiest ways to do it is using Blender. The software allows you to open STL files and export them to DXF, which is a file format compatible with all versions of AutoCAD. And after opening the DXF file in AutoCAD, you’ll be able to save it as a DWG file. The steps are simple:
If you don’t have Blender installed in your computer, don’t worry. There are online converters that allow you to upload STL files and transform them into DWG files with just one click. The website CAD Forum offers a free web application that converts STL files to DWG files. You can upload files of up to 20 MB with these simple steps:
As you can see, converting STL files to DWG isn’t that hard. We recommend using the open-source software Blender because it will allow you to manipulate your mesh. Hopefully, this guide has answered your conversion question.
