applySelector() classifies elements via OBC.Classifier.byCategory(), then maps the selector type names to matching categories using prefix matching (so IfcWall also covers IfcWallStandardCase), and calls hider.isolate() to show only matching elements. Supports simple type names and + union syntax. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
