Is the software that allows you to upload your PDF files and access them online on your iPad. I first saw the software on the konstrukshon website.
The software is much more than just provide your drawings on your iPad. One of the things I like about this software is that it takes a set of drawings in a single PDF file and packages them so that you can see each drawing individually on thumbnails. The other thing I like about the software is that you can measure on the PDF drawings.
