Geometric Constraints#

The geometric constraints module provides tools for detecting and verifying implicit geometric relationships between drawing entities.

Purpose#

Technical drawings contain implicit geometric constraints that are not explicitly annotated but are essential for proper interpretation. This module detects:

  • Parallelism: Edges that are parallel to each other

  • Perpendicularity: Edges that meet at right angles

  • Tangency: Curves that are tangent to lines or other curves

  • Symmetry: Elements that are symmetric about an axis

  • Collinearity: Points or edges that lie on the same line

  • Concentricity: Circles or arcs that share the same center

These constraints are useful for:

  • Validating drawing correctness

  • Understanding geometric intent

  • Automated feature recognition

  • Design rule checking

Note

Because development is ongoing, detailed documentation for geometric constraints is not yet available. Please refer to the API Reference for available classes and methods in the drawing_tools.constraints module.
