Pocket CAD 3D

Pocket CAD 3D brings parametric modelling to your Android phone. Draw a sketch, dimension it precisely, turn it into a solid and export an STL for 3D printing: all with your fingers, wherever you are, even offline.

PRECISE, TOUCH-FIRST SKETCHING
• Polylines, rectangles, circles, three-point arcs and splines
• Sketch on the XY, XZ and YZ planes or directly on a model face
• Grid and point snapping with assisted orthogonality
• Distance, length, angle, radius and diameter dimensions
• Geometric constraints: coincident, horizontal/vertical, parallel, perpendicular, tangent, concentric, symmetric, equal and more
• Clear diagnostics for conflicting or redundant constraints
• Fillet, chamfer, trim, extend, offset, mirror, linear and circular patterns, text converted to outlines

FROM SKETCH TO SOLID
• Extrude profiles, including concave ones and profiles with holes, in normal, reversed or symmetric direction
• Through-all cuts
• Revolve from 1° to 360°
• Every operation can add or remove material

3D FILLETS AND CHAMFERS
• Tap the model edges and choose a radius or distance
• Works on straight and curved, convex and concave edges, such as hole rims
• Spherical corners where three fillets meet

TRULY PARAMETRIC MODELLING
• An operation timeline you can always edit: change a dimension and the model regenerates
• See the status of every operation at a glance (valid, warning, failed)
• Undo/redo and automatic project versions

INSPECT AND MEASURE
• 3D viewport with orbit, pinch zoom and two-finger pan
• Animated standard views: isometric, front, back, sides, top and bottom
• Measure between faces: area, minimum distance, centroid distance, angle and axis deltas
• Section view with plane, offset and transparency
• Per-project units: mm, cm or inches

EXPORT AND SHARE
• Binary STL export, ready for your slicer
• Share the STL straight to slicers, chats or cloud storage
• Save and share the .pcad project
• Back up all projects into a single zip file

PRIVATE AND OFFLINE
• No account, no sign-up
• No Internet permission: your projects stay on your device
• Ready-made templates (cube, bracket, spacer) to get started right away

Pocket CAD 3D is perfect for makers, 3D printing enthusiasts, students and designers who want to sketch or fix a part on the go, without waiting to get back to a computer.
