  • Naming Conventions: None.
  • Template Application: None.
  • Geometric Parameters: None.
  • Randomization Controls: None.
  • Color and Material Settings: None.
  • Level or Height Information: None.

Outputs Generated:

  • CSV report (Clash_Detection_Report.csv) with clashing element categories and IDs.
