Part Maker

  • Fixed an issue where loading a .cqdiadef file incorrectly scaled the diagram data. Added new button to manually reset boundary if the .cqdiadef file is saved in different display scale.
  • Fixed an issue where Pressure-drop diagrams with low pressure-loss or airflow values created by Part Maker would show blank preview in the HVAC Supply, Return, and Exhaust tools.
  • Fixed an issue where converting an exported CSV file to CDB failed after the CSV has been edited and saved in Excel or LibreOffice. 

Terminal/ Duct Sound and Pressure Loss

Upgraded the tools by adding parts to HVAC Catalogue/Command set.

Duct Sound & Pressure Loss

  • Fixed an issue where Pressure loss was not calculated for ducts between splitter and collector fittings and would show 0.0 Pa.
  • Updated manufacturer data for Pressure-loss calculations for rigid and flexible ducts.
  • Fixed the issue where the acoustic report omitted fittings and connecting ducts, even though those components appeared in the pressure report.
  • Fixed an issue where calculated pressure and acoustic values are missing from the properties of Fittings, and some Fittings would show an incorrect “CQPressureDrop” Parameter value.

Air Terminal

Fixed an issue where repeatedly inserting air terminals from a user catalogue caused insertion errors and could eventually crash Revit.
