Edge Angle Select
This utility allows for the selection of mesh components based on their “Edge Angle” – the angle between the normals of two polygons sharing a common edge. Built to streamline the selection of hard edges, mechanical seams, or specific geometric features, the tool is written using the Maya Python API to ensure high performance on dense meshes.
Note: non-manifold geometry (with edges shared by more than two polygons) is not supported.

Features
Fully Interactive
Real-time viewport updates as you tweak the angle parameters.
High Performance
Optimized via the Maya Python API to handle dense production meshes efficiently.
