I recently had a conversation with a client . I did a 3D model of their project using Sketchup Pro (3d modeling program). Him and his wife loved the design and asked for photos to show their family. While waiting for the prints, I mentioned how he could actually download a program called “Sketchup Viewer” which would allow them to spin the model around and navigate the 3d model at their own time. Of course, they got really excited!
