Revola Edge Dranvai

Revola Edge Dranvai is a fully offline 📴 surface-of-revolution design studio for anyone who thinks in turned forms — potters, woodturners, product designers, and the mathematically curious. Sketch a side profile and watch 👀 it spin, in real time ⏱️, into a three-dimensional turned vessel you can rotate and inspect from every angle. Every vessel you draw is measured with genuine geometry, not guesswork. As you move each point of the profile, the app 📱 integrates the solid's volume by the disk method, computes its lateral surface area with Pappus's theorem, and checks whether the shape could actually be turned on a lathe — flagging self-intersections, interior undercuts, and walls that are too thin. The numbers 🔢 you see 👀 are the real numbers. WHAT YOU CAN DO • Studio — draw and edit a profile curve against a central axis with simple ✨ drag ✋ gestures, then flip to a live rotating 3D preview. Adjust wall thickness, revolution segments, and sample resolution and watch 👀 the form respond instantly ⚡. • Analysis — read your vessel as a family of charts 📊: a cut-away profile view, cross-sectional area by height, and cumulative volume, with a draggable scrubber that reports the exact values at any height. • Library 📚 — save 💾 your designs, browse them as a specimen grid or list 📋, and reopen any one to keep refining it. Attach a real-world reference photo 📸 to a vessel — shoot it with the camera or import it from your gallery — so your design sits beside the object that inspired it. • Dashboard 📊 — a live overview of your work: a featured rotating vessel, real statistics drawn from your own library 📚, and quick ways to resume or start 🚀 fresh. BUILT TO WORK ANYWHERE There is no account, no sign-up, and no connection required. Everything runs on your device 📱, so the tool 🛠️ is just as fast ⚡ on a workshop bench with no signal as it is at your desk. Revola Edge Dranvai keeps your designs local and your workflow uninterrupted. Whether you are prototyping a bowl, a bottle, a goblet, or a shape that has never existed before, Revola Edge Dranvai turns a single drawn curve into a measurable, turnable, three-dimensional object — and tells you the truth about it.
