Revola Edge Dranvai

Revola Edge Dranvai is a precision design tool for turned vessels — bowls, bottles, goblets, and anything shaped on a lathe or potter's wheel. Draw a half-profile with draggable control points and the app instantly revolves it into a live, spinning 3D model. Every edit triggers real geometric computation: volume, surface area, fill ratio, and wall-cavity shape are recalculated on-device in real time, giving you exact numbers before you ever touch your tools. At the core is a rigorous turnability engine that runs three independent geometric checks on every profile change. If your shape doubles back on itself, if the interior wall pinches or self-intersects, or if the cavity creates an undercut that no lathe tool can reach from the mouth, you get a precise diagnostic — not a generic warning. The three-mode studio — Profile, Solid, and Check — lets you inspect your design from every angle, adjust wall thickness and revolution resolution, and toggle between polyline and Catmull-Rom smooth curves. A reference photo from your camera or gallery can be pinned alongside your profile for direct comparison. The Analysis screen takes you deeper: three live domain charts — radius vs. height, cross-sectional area vs. height, and cumulative volume vs. height — give you a full geometric portrait of your vessel. A draggable height scrubber lets you read exact values at any sample point. Your saved vessels are stored in a library where each piece is rendered as a procedural silhouette drawn from its own real profile data. The Dashboard highlights your collection at a glance: total vessel count, combined volume, and best fill ratio across all saved designs. Revola Edge Dranvai runs entirely on your device — no account, no cloud, no connectivity required after launch. Whether you are a studio potter planning a production run, a woodturner evaluating a blank, or a designer sketching hollow forms, the app delivers the geometric rigor to get it right before you pick up a tool.
