Microsoft has launched their 3D Builder app for Windows 8.1. It allows people to take 3D object (already included in the app) and modify them. They include household items, toys, etc. It is a "from scratch" design app. It rather takes other designs and lets you modify them. Looks like Microsoft doesn't want to be left out of the 3D marketplace :)
