Shapr3D developing a CAD app for the iPad Pro
The basic features of this solid modeling app utilizes a smart snapping engine and taps into the capabilities of the Apple Pencil. With the basic pencil interaction, it can cover up to 75% of the modeling, and that is without using any of the tools yet.
Shapr3D Founder / Developer Istvan Csanady added that are rolling out a version for early adopters in January 2016.
A sneak peek on how the app would look can be seen below.
