This Blender add-on provides a comprehensive toolset with nearly 30 advanced node groups designed to solve a variety of geometry and numerical problems.

Currently, the toolset includes the following categories:

• Curve Boolean: Perform boolean operations (Union, Intersect, Differencece) on curves.
• Intersect: Solve intersections between lines, curves, planes, and meshes.
• Point: Calculate the distance between a point and lines/curves/planes/meshes and closest point.
• Numerical: Solve numerical problems.
• Utilities: A collection of useful utility nodes.

While many add-ons focus on creating eye-catching visual effects, this toolset is dedicated to essential geometric and mathematical operations, such as line-line intersection, point-in-polygon, and normal distribution. This toolset is primarily inspired by Rhino Grasshopper and brings many of its powerful nodes into Blender’s Geometry Nodes. More nodes will be added in future updates to further expand functionality.
