________________________________________________________________
Last Updates:
- [2026.07.19] V1.3 Improved error handling inside functions
- [2026.07.19] V1.2 Optimize removed viewtype filtering since cad.OwnerViewId already returns a valid view type
- [2026.07.19] V1.1 Optimize scanning view from FilteredElementCollector to utilizing cad.OwnerViewId
- [2026.07.18] V1.0 Rewrite code, removed FilteredElementCollector inside the loop
- [2026.07.12] V0.2 Stress test code (Code runs too slow and very inefficient)
