“I have worked in the field of Industrial and Architectural Design for 40 years, and have witnessed numerous 3d viewering applications come and go. The most encouraging was the export to interactive .pdf 3d formats allowing anyone with an Acrobat Viewer or .pdf viewer to interact with the design intent in an immersive way.
Support of these programs was often not good, and the cost was also prohibitive, but the people at ProtoTech Solutions have made this an attractive package as to price point, and their on going support has made it an integrated and highly functional part of our design process and for development to RPD output.”
– Paul L. James, Design Source International
“Software works great, even better then I hoped for. It converts everything flawlessly, fast conversions, PDF is very accurate, rotates perfect in Adobe Reader. VERY GOOD software, easy to use. From 0 to 10 I would give it 12.
