STL Viewer

STL Viewer is an advance application for downloading and viewing the contents of Stereo Lithography files. STL files are representations of the surfaces of solid models that have been created in CAD programs. STL files are a neutral format that can easily be generated by almost all CAD systems. Now you can take your favorite models with you to show others.

A picture-in-picture feature provides another 3D view of the model that can be manipulated independently.

The user interface supports zooming, panning and full 3D rotation of the model. It can also export the screen image to the photo album for other uses such as emailing.

The current version support ASCII and binary format. STL files can be imported from iTunes as well as email attachments and AirDrop.
Imports from Files and iCloud have been recently added.

The following values are also provided for each model:
Axis aligned box volume and dimensions. The volume of the surface, the surface area and model weight are calculated as well.
