ExcelsisView 1.1.23 opens the active DXF/DWG model or paper space instead of drawing both together. Large read-only DWGs now use cached drawing paths, indexed hit-testing, bounded feature-list output, and defer editable contour analysis until Save As DXF. The responsive two-row DXF toolbar behavior from 1.1.22 is retained.
The complete clean build, dependency, containment, format, privacy, provenance, licensing, corresponding-source, packaged-byte, and antivirus gates passed. See AUDIT-1.1.23.md in the repository for detailed evidence and caveats.
The Windows installer is unsigned and may trigger SmartScreen. Microsoft Defender was disabled on the build machine; Kaspersky 21.26.4.406 with 2026-08-11 bases scanned the exact candidate assets and extracted runtime with zero detections or suspicions.
