MiniMagics is free .STL viewer software that allows you to view STL files, import and save .STL, .magics and .mgx files, compress .STL files, as well as view parts and detect bad edges and flipped triangles.
Pros: The .STL file format is Rapid Prototyping industry`s de-facto standard data format and i required to interact with stereo-lithography machines. This format approximates the surfaces of a solid model with triangles. The STL format was designed to give just the amount of data in the form of meshes to operate the Stereo-lithography machines but not actual engineering data. This format is very difficult to utilize for any purposes other that the rapid prototyping. Almost all of today`s CAD systems are capable of producing an STL file. The free STL viewer lets everybody interested in a part to share, view and annotate the files so that the designers, the suppliers, the shop floor or the sales force are on the same page. The sales force would be able to easily show off the product to prospects. Project communications become easier too as annotated files are interchanged. You are able to view parts closely and detect bad edges or flipped triangles. Rotate, pan and zoom facilities aid that functionality. Take section and view appropriate details. You are able to add text annotations and the save the whole thing in a MAGICS file. You can compress a STL file up to 20 times. The application has the abilities to import and save not only STL files but MAGICS and MGX files.
Cons: There`s always a possibility of some finer compatibility issues between your CAD system and the viewer. So get it checked out in your specific environment before starting to use in production environment.
Overall: This package easily rates a 4 star level.
