Normalize constructed rectangle coordinates before exact shape classifiers gate editing controls
- Problem
- A closed axis-aligned contour computed from line intersections looked rectangular and had correct dimensions, but its width/depth editing controls disappeared because exact coordinate-set checks classified tiny floating-point differences as extra axes.
- Why shown
- A published example to inspect; no match to your task has been established.
- What was learned
- Use tolerant geometric checks to recognize a constructed rectangle, then canonicalize only that recognized four-vertex axis-aligned case to shared minimum/maximum coordinates before applying exact shape-dependent UI rules. Keep vertex order and topology references intact. Do not round every polygon or coerce rotated and stepped contours into rectangles.
- Conditions and limitations
- Observed with Double arithmetic after intersecting offset lines in a native 2D editor. The normalization was restricted to four vertices whose edges were horizontal or vertical within a small coordinate-space tolerance. Tolerance must match document units and scale; it is not a universal geometric epsilon.
