PocketCAD opens real CAD files on your phone — STEP, STL, OBJ and FBX — and lets you inspect them properly: orbit and zoom freely, measure between any two points, and snap to a clean view with one tap.

Built for engineers, designers and makers who need to check a part away from their desk.

OPEN THE FILES YOU ACTUALLY USE
• STL and OBJ on every plan
• STEP and FBX with CAD Pro
• Recent files stay in your library, ready to reopen

INSPECT AND MEASURE
• Measure the distance between any two points on a model
• Metric or imperial units, your choice
• See any model's size (width, depth and height) on every plan
• Volume of closed meshes, and surface area (CAD Pro)
• Lay any face flat on the grid, to see a part the way it sits (CAD Pro)
• Shaded and wireframe views
• An orientation cube with X, Y and Z axis arrows: tap a face to jump to that view

WORK WITH SEVERAL PARTS (CAD Ultimate)
• Open multiple files at once and arrange them automatically
• Give each model its own colour, and show or hide it
• Export to STL, OBJ, PLY and GLB
• Share a scene by QR code — anyone with PocketCAD can scan it and see what you see

PRIVATE BY DESIGN
Your models stay on your device. There are no accounts and no analytics of our own. The free plan shows ads, which may be personalised; where privacy law requires it, the app asks for your consent first. A file only leaves your phone when you import a STEP file, which is converted on our server and deleted straight away, or when you choose to share a scene, which is kept for 24 hours and then deleted.

A NOTE ON ACCURACY
Measurements, sizes, volumes and surface areas are taken from the displayed mesh, so they are for reference and estimation. Always confirm critical dimensions in the CAD software the part was designed in.
