The fastest way to waste an afternoon is opening a CAD file on a phone with the wrong app. Done right, it is the opposite: the right CAD viewer makes the drawing live in your pocket.
Step 1: Zoom, pan, and rotate
Pinch to zoom, drag to pan, and rotate 2D or 3D views to inspect from any angle. Smooth rendering keeps even heavy models usable on a phone.
Step 2: Start with a clean import
Open CAD viewer and bring in the DWG, DXF, or native CAD file straight from Files, an email attachment, or a cloud drive. It renders at full fidelity - no flattened previews, no missing geometry.
Step 3: Measure before you assume
Pull distances and areas straight off the drawing with the built-in measuring tools. No manual unit conversion and no guessing at scale.
Step 4: Work offline when you need to
Down the drawings you will need before you lose signal. A good CAD viewer stays usable when the site has no Wi-Fi.
Tip: watermark everything that leaves the building. It costs seconds and it is the difference between traceable and anonymous.
Set it up once and the workflow sticks. A CAD viewer that handles viewing, markup, and sharing in one place is one less thing to think about.
