It also depends on what modification you want to do. So I'm sure all these packages have the capability to clean up models, scale, reposition, ect. I use netfabb on every model to make sure its oriented properly prior to slicing. However lets say you had a counterbore that you would like to make larger. Do any of these modelers allow you to do something like that?įrom the STL? Any mesh modeller will allow you to manipulate the mesh itself like pushing and pulling surfaces as well as individual vertices. You can also just difference a cylinder from the model to get a larger hole. Or union a cylinder to it then difference another from it to get a smaller hole.All these software will help you view, edit, draw, analyze, save, import, export, and print STL files. You can easily open a 3D model and use various tools to edit. You can view and edit CAD data instead of 2D drawing. It is a triangular representation of 3D structure of an object. Surface of the structure is broken into small facets. You can easily edit, redraw, and analyze 3D object. It lets you view and examine each section of the 3D object. It can also measure various dimensions and other data. You can use various tools to edit and view like wireframe, shade skin, rotate, pan, mirror, scale, etc. If you want to view the construction of any model then you can import the STL file in any of these STL viewer software.

It lets you open, view, and edit an STL file. You can view each section of the model by rotating, panning, zooming, etc.
