A geometric solver (more formally known as a geometric constraint solver) is a specialized software component or algorithm used to calculate the positions, sizes, and orientations of geometric shapes based on a set of rules, dimensions, and constraints. It serves as the mathematical engine behind modern Computer-Aided Design (CAD) software, 3D modeling tools, and engineering applications. How Geometric Solvers Work
When a user draws a sketch in a CAD application, they define two types of parameters:
Dimensional constraints: Specific numerical values like distance, lengths, radii, and angles.
Logical/Structural constraints: Geometric relationships like parallelism, perpendicularity, tangency, concentricity, and horizontality.
The solver takes these rules, translates them into mathematical equations, and instantly solves them. If you change one dimension, the engine recalculates the entire shape while preserving all other rules. Common Solving Methodologies
Solvers generally approach these complex mathematical problems through a few primary methods: Geometric Constraint Solver – C3D Solver
