<p>BeeGraphy Editor Tools Package

This package contains a comprehensive set of tool nodes designed to assist with various operations and analyses in the BeeGraphy Editor.

Usage

The nodes in this package are categorized into specialized groups to simplify design and modeling tasks. They enable users to create, manipulate, analyze, and transform models with precision. To locate these nodes, browse the corresponding groups in the menu or use the search functionality.

Node Groups

Surface Group

The Surface group provides nodes for creating and manipulating surfaces. These nodes enable you to generate freeform surfaces, analyze surface properties, apply surface transformations, create panel structures, perform surface boolean operations, and convert surfaces to triangulated meshes. Surface nodes are essential for working with complex surface geometry and creating smooth, continuous surfaces in your designs.

Vector Group

The Vector group contains nodes for vector operations and calculations. These nodes allow you to perform vector addition, subtraction, normalization, dot products, cross products, and various vector transformations. Vector nodes are fundamental for working with directions, positions, and spatial relationships in 3D space.

Transform Group

The Transform group provides tools for applying geometric transformations to objects. These nodes enable translation, rotation, scaling, and combined transformations. Transform nodes are essential for positioning, orienting, and resizing geometry in your designs.

Primitive Curves Group

The Primitive Curves group contains nodes for generating basic curve shapes. These nodes allow you to create fundamental curves such as lines, circles, arcs, splines, and other geometric primitives. Primitive curve nodes serve as building blocks for more complex curve-based designs.

Curve Analysis Group

The Curve Analysis group provides nodes for analyzing curve properties and characteristics. These nodes enable you to measure curve length, evaluate curvature, check continuity, extract points along curves, and analyze curve geometry. Curve analysis nodes are valuable for understanding and validating curve properties in your designs.

Curve Toolset Group

The Curve Toolset group offers utility nodes for curve manipulation and processing. These nodes provide tools for curve editing, trimming, extending, joining, and various curve operations that enhance curve-based workflows.

Curve Triangulation Group

The Curve Triangulation group contains nodes for converting curves into triangulated representations. These nodes enable you to create mesh representations of curves for rendering, analysis, or further processing.

Boolean Operation Group

The Boolean Operation group provides tools for performing Boolean operations on geometry. These nodes enable union, difference, and intersection operations on surfaces, solids, and regions. Boolean operation nodes are essential for combining, subtracting, and intersecting geometric objects to create complex shapes.

Solid Group

The Solid group contains nodes for creating and modifying solid geometry. These nodes enable you to generate primitive solids, create freeform solids, analyze solid properties, apply solid transformations, perform solid boolean operations, and convert solids to meshes. Solid nodes are fundamental for working with three-dimensional solid objects.

Intersection Group

The Intersection group provides tools for finding intersections between geometric entities. These nodes enable you to find intersections between curves, surfaces, solids, and other geometric objects. Intersection nodes are valuable for determining relationships between geometric elements.

Text Group

The Text group contains nodes for generating and manipulating text objects. These nodes enable you to create text geometry, apply text transformations, and work with typography in your designs. Text nodes are useful for adding labels, annotations, and text-based elements to your models.

Image Group

The Image group provides tools for processing and incorporating images into designs. These nodes enable you to work with image data, convert images to geometry, and use images as design references or textures.

Analysis Group

The Analysis group contains nodes for data and model analysis. These nodes enable geometric analysis, structural assessments, property calculations, and various analytical operations that help you understand and evaluate your designs.

Array Group

The Array group provides tools for creating arrays and repeating patterns. These nodes enable you to create linear arrays, rectangular arrays, polar arrays, and other pattern arrangements. Array nodes are useful for duplicating and arranging geometry in systematic patterns.

Toolset Group

The Toolset group offers general-purpose utility nodes for enhancing workflows. These nodes provide various helper functions, conversions, and utility operations that support and streamline design processes.

Triangulation Group

The Triangulation group contains nodes for converting geometry into triangular mesh representations. These nodes enable you to create mesh versions of surfaces and solids for rendering, analysis, or export purposes.

Each group provides specialized nodes tailored to specific tasks, streamlining complex design and modeling workflows in the BeeGraphy Editor.
