fix(revit) #3615: include gutters and other subcategories in Revit connector sending "everything"

[jcesarpolo]

Description & motivation

• Linked to: Revit Connector: Gutters not converted when sending "everything" #3615
• This PR fixes an issue where gutters, roof soffits, fascias, wall sweeps and slab edges were missing when using the "Export Everything" option in the Revit connector.
• The fix ensures that these subcategories are correctly included in the exported data.

Changes:

• Modified IRevitDocumentCacheExtensions.cs:
  • Previously CacheInitializer() looped only through the categories in Autodesk.Revit.DB.Document.Settings.Categories which returns only the top-level categories, ommiting some supported model categories.
  • Updated CacheInitializer() method to correctly include the mentioned subcategories.

Screenshots:

Result on Speckle. No Gutters

Result on Speckle after the fix (Roof Soffits also tested)

Validation of changes:

• Tested on all supported versions of Revit to confirm the fix works across different versions.
• Avoided looping through all built-in subcategories to prevent unexpected results for unknown subcategories.
• Below is an example of artifacts that appeared when including all built-in subcategories supported:

Thank you @jcesarpolo, this looks simple enough to review and merge!

Tested in 2022 and 2025. lgtm

yep, so this adds extra categories (see diff) to both the Categories filter and Everything filter (since they use the same internal cache.

This is good, I've checked it works correctly for both filters, and that it doesn't lead to duplicate elements, we simply were not sending categories like wall sweep and gutters from either the Categories or Everything filters before.

I just want to do a final check in Revit 2021, since there may be differences in categories behave in the older versions

2021 looks ok
