Thank you for your feedback! New features in this release: New: 3D mode reconstructs silkscreen text into smooth-rendered line capsule primitives and supports dashed line styles; New: 3D mode enables rendering of blind, buried, and through-hole via wall metallization with copper plating, and introduces radial inward compensation for via diameters; New: 3D mode supports high-fidelity rendering of footprint-level copper shapes (fp_poly, fp_line, fp_text); New: 3D mode supports automatic edge drilling clipping and precise contour trimming for non-circular slot holes; Improved: Expression parsing kernel now uses thread-safe high-precision floating-point conversion, significantly enhancing large file loading speed; Improved: Reconstructed layer alias mapping system enables O(1) fast lookup across the entire footprint lifecycle and improved layer organization; Improved: Decoupled document loading from thumbnail generation, enabling asynchronous background rendering of thumbnails; Improved: Enhanced grid triangulation algorithm strengthens area and perimeter conservation checks for complex polygon topologies; Fixed: Routing traces and arcs are reconstructed as continuous closed capsule geometries, eliminating endpoint voids via nonzero winding number detection; Fixed: Resolved issue where pad and copper side walls in 3D mode appeared completely black under PBR lighting due to missing normal vectors; Fixed: Addressed mesh generation and triangulation defects at keyhole bridging notches between solid silkscreen and copper polygons; Fixed: Fixed problem where overlapping pads or adjacent SMD pads could occlude through-holes during inter-layer penetration; Fixed: Resolved occasional anomalies where pad geometry cache and layer state became desynchronized during undo/redo operations.
