The data-model package provides the core classes for interacting with AutoCAD's database and entities. This package mimics AutoCAD ObjectARX's AcDb (Database) classes and implements the drawing database structure that AutoCAD developers are familiar with.

/**
 * Represents a three-point angular dimension entity in AutoCAD.
 *
 * This dimension type measures the angle between two lines or edges by defining three points:
 * a center point and two points that define the lines or edges being measured. The dimension
 * displays the angle value and typically includes extension lines, dimension lines, and arrows.
 *
 * Three-point angular dimensions are commonly used to measure angles between non-parallel lines,
 * angles of arcs, or any angular measurement that requires three reference points.
