Once a Glass Type has been selected from the list and it highlights in orange, it may be applied.

If any of these new glazing types do not exist already in Revit, they will be added to Revit’s list of Glazing Types.  Applying a type from the Glass Database will change the glazing type assigned to the element in the model and write it to the Revit list of Construction types.

Glass Types which are chosen from the list but not already in Revit, will be updated to the model when Revit is closed and restarted. This allows the database in Revit to be modified and the updated file to be read in the next Revit session. (Revit 2020 and 2021 may update immediately or sometimes may need to be restarted).

Glass Types which are already in Revit’s internal list, will be substituted immediately for the existing glass type. Once the new Glass Types have been added to Revit’s internal list, they may be swapped out in future without any restart and will be available for any project.

New Glass Types that are not in Revit are added after restarting Revit

The results will update after Revit is relaunched.  You may also apply several Glass Types to different elements and then restart Revit to apply all these changes at once.

Glass Types that are selected from the list in the Glass Database, that are already in Revit’s list of Analytical Construction Types, will be applied to the model immediately (the existing Glass Type will be swapped out for the chosen entry).

Revit stores a list of construction types and materials internally in a file.  FenestraPro allows this file to be easily edited and updated using a simple interface.

The model should be saved before closing Revit (in case other changes have been made earlier). There is no need to save the model after changing the Glass Type in the database.  The next time that Revit is launched and FenestraPro is opened, a message will display to remind you to confirm the changes from the previous session.

You may choose:

  1. Yes (the changes will be made to those elements that were selected previously)
  2. No (this session of FenestraPro will not use those changes.  A further session of FenestraPro will remember the changes and show this message again)
  3. Don’t ask me again (pending changes from the previous session will be deleted and you will not be reminded again)

Note: If you close the project and re-open (without closing Revit), you may see the message that you have unsaved work and asking if you wish to apply this.  This workflow will not see the new Glass Type applied however (a restart of Revit is required).  If the project is subsequently closed and re-opened, the Glass Type may also not be applied.  Following the correct sequence (Change the Glass Type(s) using FenestraPro – Close the project – Close Revit and relaunch) will ensure that the Glass Type chosen will be applied correctly.

There may also be isolated instances where the Glass Type is not substituted in Revit after being selected in the database list.

Note: If Revit’s Edit Type window is open, this will prevent any changes being made. Please ensure that the Edit Type window is closed before using the Glass Database.

If for any reason, the properties cannot be changed you will see a message showing that the families could not be updated.

Note: If you have made separate glazing family types in Type Properties for different areas of the model but did not save these changes before closing the model, these new family types will not appear in the model when Revit is restarted.  Glass Types which were applied to these family types will then be cancelled.

When applying a new Glass Type, a message may display asking if you wish to apply these changes only to this Surface (instead of all instances on the model where this element type is located). If this is your intention, a new family type for this window or curtain panel will be created with the product name of the Glass assembly.  If properties for this element are subsequently modified, the name of the family type may not match the actual analytical properties (there will be a mismatch).  In this case to avoid confusion, please rename the family type to match the properties chosen.

There may be instances where the glass type does not update in Revit.  This may be due to:

  1. Type Properties are open for that element in Revit
  2. The setting for ‘Define Thermal Properties by‘ under Analytical Properties is not set to Schematic Type but is set to User Defined (custom values) or Building Type.
