Looking for an Architecture & Landmarks asset? The Spiral Duct is a finished, render-ready model at $34. Counted at the source, the model is 40,526 polygons and 40,822 vertices. How that lands depends on your renderer and on how close the camera gets.

Its measurements are 211.11 x 34.16 x H358.77 cm, taken from the object rather than eyeballed. Being StemCell, it arrives in several formats built from one source, so the version you open is not a lossy conversion of another. The scene is organized rather than dumped into a single mesh, which makes selective texturing and partial reuse practical.

It is cataloged for architectural visualization, technical visualization and software demos. It is aimed at architectural visualization, city scenes, advertising renders and VR walkthroughs.
