Interface Point2D

@ifc-lite/drawing-2d

2D architectural drawing generation from IFC models. Generates section cuts, floor plans, and elevations with:

• Cut lines (geometry intersected by section plane)
• Projection lines (visible geometry beyond cut)
• Hidden lines (occluded geometry, dashed)
• Silhouettes and feature edges
• Hatching (material-based fill patterns by IFC type)
• Vector output (SVG)
