Add SwichDesign automatic dimensions extension by Swichllc · Pull Request #3492 · pyrevitlabs/pyRevit

automatic dimensions extension

Description

Added SwichDesign.extension with automatic dimensioning for Revit. Includes three main library modules (geometry, revit_io, standards) providing pure geometry algorithms, Revit API integration, and US architectural dimensioning standards. The main button implements exterior (multi-tier wall/opening dimensions) and interior (room-driven) dimensioning modes with support for angled buildings via frame transformations, core/finish face selection, and opening dimensioning modes.

Update .gitignore to allow this extension in the repository.

Pull request overview

Adds a new SwichDesign.extension button under the main pyRevit tab to automatically place exterior and interior dimension strings in Revit floor plans, backed by a small internal library split into geometry (pure algorithms), Revit API I/O, and dimensioning standards.

Changes:

Introduces the Automatic Dimensions pushbutton script with exterior (multi-tier) and interior (room-driven) modes plus a WPF configuration dialog.
Adds autodimswichdesign helper modules for geometry processing, Revit element/reference discovery, and US-style dimension spacing/formatting rules.
Provides a localized bundle.yaml tooltip/title describing usage and behavior.

"Dry run" feature the testing and the ability o run the code without populating the model - testing for issues with the model geometry that might lead to failure

General opinion:

I wouldn't add a new extension folder to the repo, either find a place or have it a separate repo
as it's US only, it may be too specific for the general tools?
as all other tools are translated by now, the resource dictionaries for other languages should be in there. Don't know if it's US only though.
if there's an actual issue like this title indicates def pyrevit_config_broken(): I'd try to fix that instead of some workaround
as this is a new tool, I wouldn't leave stuff like saved by older versions which indicates iterations during development in there
if libs aren't actually reusable by other tools, just place them in the same .pushbutton folder
I'd rely on internal tools DB.UnitFormatUtils instead of custom stuff like this def format_ft_in(value_ft):

jmcouffin · 2026-07-22T18:38:31Z

@Swichllc I agree with @Wurschdhaud comments and more importantly on

if libs aren't actually reusable by other tools, just place them in the same .pushbutton folder

Move the Automatic Dimensions tool from SwichDesign.extension into pyRevitTools.extension and register it in the Drawing Set panel. Rename the package to autodim and refactor internals: add a document-scoped opening index with reset_opening_cache(), switch to a document-aware format_length (uses pyrevit DB/DOCS/HOST_APP), and replace the tool's custom settings persistence with pyrevit's script.get_config()/script.save_config(). Miscellaneous docstring/comment cleanup and other small fixes to improve performance and correctness.

@jmcouffin @Wurschdhaud I believe I addressed all the comments if you guys want to take a look
Thanks

script.get_bundle_file() does the same - minor nitpick

@Wurschdhaud I would not be able to get to it this week, (claude usage limits nonsense - coding by vibes only:) Would you be able to check if making your changes affect the tool?
and regarding where it is going to be - I have no issue to move it - I was just trying to keep it visible, from my personal experience, the buried dropdown tools are not easy to find unless you know exactly where the tool is.
Thanks

For the visibility, good comms at release plus a video and some social media can get you a long way

- black formatting - move lib stuff one layer up - add context to bundle file - move format helper to units.py - simplify some imports and general handling

Wurschdhaud · 2026-08-04T18:33:56Z

Implemented what jumped into my eye, still seems to work, give it a swing.

Note:

I don't think it should be "top layer" but rather burried down, simply because the toolbar would probably exceed a 1920 pixel screen
resource dic's for other language are still missing - but if it's US only, that may be ok

Swichllc · 2026-08-07T00:15:23Z

@Wurschdhaud thank you for taking care of that - I went over it, tested it, seem to work as before, so I'm good on my end.
The top layer vs drop down menu - not a big deal for me, If you and @jmcouffin tell me where or simply move it, I'm good either way. It was a thought about convenient not fame, so all good.

Thank you
