Editing STL files can be conducted in two different types of modeling software: On one hand, there is CAD software (Computer-Aided Design). It is tailored for construction, provides exact measurements and solid modeling analysis. On the other hand, there are mesh editing tools such as Ansys Meshing and other such MeshLab software. They are designed for modeling, animation, and objects expressed by a 2D surface. Both options are supported in our Additive Suite.
