To Our Users In Egypt. Etba3ly 3D found information online that will show you how to edit and repair an STL file with 7 free STL editors: FreeCAD, SketchUp blender, Meshmixer, Meshlab, 3D Slash, and SculptGL.
- On the one hand, there is CAD software (Computer Aided Design). It’s tailored for construction, provides exact measurements and solid modeling. These tools were not made for 3D printing in the first place. In CAD software, circles, for example, are “real” circles; in 3D printing – and in STL files for 3D printing – circles are represented as polygons. So CAD tools cannot show their full strength when editing STL files. Nevertheless, they can be used for working with STL files. Three of the four tools we present in this article are true CAD tools: FreeCAD, SketchUp, and Blender.
- On the other hand, there are mesh editing tools such as MeshMixer and MeshLab. They are designed for modeling, animation, and objects represented by a 2D surface. That means: These objects have just a shell and no filling. This may cause paper-thin walls, which can’t be 3D printed, if the object is not solidified (which, however, can easily be done in tools such as Meshmixer). In fact, mesh editors are excellent tools when it comes to editing STL files.
