Brain CAD: SKP Editor & Viewer

Brain CAD is a desktop-style 3D modeler for Android tablets and phones. Draw a shape, push or pull it into 3D, and keep going: the push/pull workflow, inference snapping and a Measurements box for exact values, with a menu bar, toolbars and trays like a desktop CAD app.

• Groups and components, intersect faces, soft and smooth edges
• Tape Measure, Dimension, Protractor, Text and 3D Text
