I run a 3D Printing Service bureau (proto [url removed, login to view] without the space). I would like to have an upload form that uploads .STL files to a folder on my website. Additionally, these files need to be examined to determine the volume, dimensions, and surface area of the file uploaded (STL files are 3D Modeling files). This will need to be done using some type of program as the volume, dimensions, and surface area is not stored in plain text as far as I know anywhere in the file.
After the file has been uploaded, I would like to return the price to produce the models (based on simply computations on the volume, dimensions, and surface area that I can provide).
