In ZBrush terminology, a "Curve Tube" refers to any 3D mesh generated along a user-drawn spline (curve) that maintains a tubular or cylindrical profile. Unlike drawing a cylinder with a standard brush, Curve Tubes automatically conform to bends, twists, and changes in elevation. zbrush curve tube

At its core, the is a brush mode that allows you to draw three-dimensional geometry onto a surface using a two-dimensional stroke. Unlike standard brushes that displace existing geometry, Curve Tube generates new geometry based on a user-defined path. Curve Tubes automatically conform to bends
