Mesh is a parametric shape generator that adds a variety of 2D and 3D forms directly to the Blender viewport. It enables the creation of primitives such as polygons, stars, gears, arches, domes, pipes, bolts, and geometric spheres. Users maintain fine-tuned control over specific profile parameters, including segment counts, size, thickness, inner ratios, curvature, taper, and twist.

The tool operates through a custom tab in the 3D viewport and features content-aware editing. It includes presets for transitioning between 2D and 3D modeling states, making it useful for rapid blockouts, detailing mechanical components, and building ornamental patterns.
