Analysis nodes help you understand geometry beyond its shape. They extract dimensions, centers, extreme points, and cross-sections - the measurements needed for verification, fabrication planning, and parametric relationships. These nodes accept any geometry type (curves, surfaces, solids) and output numeric values and points that can drive downstream logic.

Bounding Box

Behavior

Computes the smallest axis-aligned box that fully encloses the input geometry, then outputs only the box's measurements - no physical box geometry is produced. The Bounding Box is always parallel to world XYZ, so for rotated or tilted geometry the measured volume may be larger than the tightest possible fit. Use Bounding Box Union when you need a tighter fit aligned to a custom plane.

Bounding Box Union

Behavior

Computes the smallest box that fully encloses the input geometry, oriented to a specified plane instead of world axes. Like Bounding Box, it outputs only the resulting dimensions - no physical box geometry is produced. By aligning to the input plane, it produces a tighter fit for rotated or tilted geometry than the standard Bounding Box, which is always world-axis-aligned.

Extremes

Behavior

Finds the highest and lowest points of geometry relative to a specified plane direction (XY, YZ, or XZ). The "highest" and "lowest" are measured along the input plane's normal direction. Useful for finding top/bottom of a model, clearance checks, or aligning geometry to its extreme positions.

Centroid

Behavior

Calculates both the geometric center (bounding box center) and the mass center (center of mass) of a curve, surface, or solid. The geometric center (Bbox) is the midpoint of the bounding box - quick but not always accurate for irregular shapes. The mass center (Mass) accounts for the actual shape distribution and is the true balance point of the geometry.

Contour

Behavior

Generates a series of equally spaced curves by slicing geometry along a given direction or plane. Creates cross-sectional profiles at regular intervals. The spacing and direction of slices are controlled by the input plane and count/distance parameters. Commonly used for section analysis, waffle structures, and contour-based fabrication (stacked layers for CNC or 3D printing).
