Geometric Constraints (Alibre Design)
Rules governing the relative positioning and behavior of sketch elements.
Definition
In Alibre Design, Geometric Constraints represents a core architectural mechanism. Rules like coincidence, concentricity, parallelism, and tangent alignment applied in 2D sketches to lock the geometric relationships of profiles before 3D features are built.
Why it matters
Mastering Geometric Constraints is critical for production-grade deliverables. Establishes the parametric coordinate baseline for sketches, ensuring that downstream features recompute predictably when core variables are modified.
Common pitfalls
- Over-constraining sketches, causing solver deadlocks.
- Neglecting tangency constraints at fillet junctions, leading to G0 continuity sharp edges.
This concept is a core structural element of the Alibre Design drafting and engineering environment developed by Alibre. A high-precision, budget-friendly parametric 3D solid modeler for mechanical parts and assemblies.
