Cadrio opens technical drawings straight on your phone or tablet — on the shop floor, on site, or at a customer's, where no computer is at hand. STEP AND STL 3D MODELS Open a .step, .stp or .stl file and inspect the model from every angle. Measure distances, browse the individual parts of an assembly, and switch between perspective and orthographic views. DXF 2D DRAWINGS Zoom in on details, measure dimensions, and check the scale. MORE FORMATS PDF, images (JPG, PNG, BMP, GIF) and ZIP archives — pick a file inside the archive and open it directly, no unpacking needed. WORKS WITHOUT INTERNET All processing, including 3D models, happens on the device. The app requests no permissions, never connects to the internet, and sends your drawings nowhere. If you work with confidential documentation, there is nothing to worry about. OPEN FROM AN E-MAIL ATTACHMENT Got a drawing as an attachment? Tap it and choose Cadrio. You can set the app as the default so it opens straight away next time. TEN LANGUAGES English, Czech, German, Polish, Slovak, Hungarian, Ukrainian, French, Spanish and Italian. The language is switched inside the app, independently of your phone settings. NO ADS, NO SUBSCRIPTION A one-time purchase. No adverts, no monthly fees, no tracking. SUPPORTED FORMATS STEP, STP, STL, DXF, PDF, JPG, JPEG, PNG, BMP, GIF, WEBP, TXT, ZIP Please note: the DWG format is not supported. Convert such drawings to DXF or PDF first.
