Curve Shapes is a Blender extension that allows users to generate and manipulate geometry using Bezier and Poly curves. The tool produces clean topology based on the user's curve inputs and updates the generated mesh in real time as the curves are edited. It provides a flexible modeling workflow that is particularly useful for building organic structures like armatures and muscles.

The extension includes a contextual pie menu and an N-panel for configuring operations. Features include options for spline interpolation, boolean join and intersect operations, and automatic voxel remeshing. Users can adjust mesh resolution dynamically using keyboard shortcuts or mouse scroll inputs limitng the need to access menus. Additionally, it supports a project operation to maintain compatibility with the Multiresolution modifier and provides direct access to bevel weights and creases on the newly generated geometry.
