There is a version of mobile CAD that feels like a toy and a version that feels like a tool. A good CAD viewer is firmly in the second camp.
Step 1: Keep revisions straight
Name versions clearly and re-open the latest before a review, so you are never marking up a drawing that has already moved on.
Step 2: 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 3: 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.
Step 4: Batch your reviews
Handle several drawings in one sitting so feedback goes out together and nothing sits half-reviewed over a weekend.
Tip: bookmark the drawings you reference most. Opening the right file in two taps beats digging through folders on site.
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.
