This demo (demo.techsoft3d.com) was built using the HOOPS Web Platform. The frontend UI comes from Sanna, a design firm that we partner with. The graphics are the web viewer from HOOPS Communicator. The conversion service of HOOPS Communicator, powered by HOOPS Exchange to read CAD data, is also hosted on an AWS elastic beanstalk server. This allows you to upload CAD files and view them.
