Your file is SU v6. This means the plugin isn't compatible with SU versions that use older releases of Ruby and API.
Below is your file 'orthogonalized' with SU2020, with the same parameters as yours.
BTW, your white dashed lines indicate a better way to preserve the global shape of the face than the one I've implemented, this will become an option in the next release (I hope).
Cordialement,
Hi everybody,
Below is the beta version of my Orthogonalize plugin.
I would have some feedback from the users, so I can enhance the plugin.
Install it the usual way, with the extensions manager.
First usage: select one or more faces in the model, righ-click on the selection and select 'Orthogonalize N faces'.
Please click on the Help button and read the PDF file to get information about how the script works.
Please report any bug you encounter, and feel free to report what's good and what is not convenient to you.
Best regards
Settings are remembered all along the session, but I can also save them saved in the skp file (as model attributes).
Concerning the rounding of coordinates, it's also an interesting idea that I will look into.
Regards
Hi,
The future 'orthogonalize' plugin is on its way...
But I've encountered some problems to solve before reshaping a face: sometimes there are double points (especially when the face comes from an external content, such as an OSM map for instance), sometimes edges are reversed in the face record, sometimes there are colinear edges or overlapping edges, etc...
I've almost solved all of these and the script is under heavy testing 
Below is a preview of the interface: you'll choose between 3 options, preserve the global shape of the face, preserve the segments lengths, or click on the first segment of a single face to give the script a start.
Script will process a single face or a bunch of selected faces.
Hi,
This idea is more complex than I though 
I have writen some dirty code just to see if it is doable. It needs now heavy testing in various situations, with complex face shapes.
A threshold parameter (angle) tells the script in which range each angle at each corner of the face has to be 'orthogonalized' (or not).
For now, a face like on the left side of the image is reshaped to the one on the right
Click on the image to see it in action on a more complex face:
Interesting idea... I'll investigate the feasibility.
There should be some parameters to drive the 'reshape' process (from where to start, what dimensions to maintain, etc).

Hi,
Don't you think that (in this particular case) creating an outline would take longer than erasing unwanted entities manually ? Just a thought...

Hi folks,
As you perhaps know, I had some trouble getting my SU2020 version
https://sketchucation.com/forums/viewtopic.php?f=323&t=72448&p=659972&hilit=cranky#p659972
That's an old story now, a sort of "gentlemen agreement" has been found.
So I'm back to SU and Ruby, just wanted to inform you that a new release of my 'Numbering Text' plugin was published last week.
Here it is at the EW: https://extensions.sketchup.com/extension/7f2d2765-5fad-4cb3-b622-16a7411af4e9/numbering-text
What's new:
Enjoy !
Hi,
My guess is that if you type 1m,1m,1m instead of 1,1,1, this will create a 1 meter cube, as Sketchup will convert the unit suffixes like in all its native tools.
If this doesn't work, this means that the dialog doesn't convert your string input to lengths.

If only there was a company that gave students and educators FREE copies of ALL of their products
Autodesk is doing that: teachers and students can get a set of more than 60 softwares (Autocad, Revit, 3DS Max, Maya...), all fully functional with minor restrictions, licences expiring after 3 YEARS.
Unreal Engine (TwinMotion), Abvent (Archicad, Artlantis, BIM Office...) do so as well, licences expire yearly.
IMHO these are clever long-term strategies...
And I repeat: I ain't no stingy guy until a software publisher charges me even several bucks to promote (in some way) its product.
@unknownuser said:
Is this "trade policy" or Trimble Policy?
I'd say both.
IMHO it's a "loser-loser" strategy. (in french: "stratégie perdant-perdant")

La compatibilité s'arrêtera à SU2019. J'ai déjà plusieurs rapports de bugs avec 3 ou 4 plugins qui ne marchent plus très bien sous SU2020.
A+
Hello all,
My Educator's free licence of SketchUp 2019 expired on April 24th. A few days earlier, I asked for a new free licence of SU2020.
The local supplier sent me a proposal for 78€, so SketchUp Pro is now payware for everyone, including teachers and students.
Should I pay for training Trimble's future clients ? Should I pay to have the right to develop free plugins ? No.
I've decided to stop teaching SketchUp, and to stop developing and updating my free Ruby extensions. Not a question of price, but of principle(s).
So I'm back to SU Make 2017 
Impressionnant 
Tout ce que SketchUp devrait comporter comme outils natifs, Fredo le fait...
Impressive
Almost all what SketchUp should encompass natively is developed by Fredo...
Hi Sasha,
I'll look into your issue. Stay tuned
Hi,
There are many ways of computing the "center" of a surface.
First: what kind of surface ? Planar, Nurbs, ruled surface ?
Second: Center point can be the barycenter, centroid, average edges, average vertices, etc.
Third: what kind of output do you want ? 3D coordinates, Lat/Lon coordinates...
Regards
Hi Sonia,
Yes there is a PDF help file.
See the Help button in the lower-right corner of the dialog ? Here it is
Latest version of Compo Spray is available here: https://extensions.sketchup.com/extension/213a8e60-208f-4b6d-95ff-ab367c09a959/compo-spray
Hi,
I haven't SU2020 yet, but it works with my SU2019, apparently just a matter of loading policy, as TIG said.
Hi Juju,
I wish I had the time to enhance Windows Builder (and LOD Labels plugin too), but I'm busy on SU/Twinmotion projects for a couple of months now. I'll be back on Ruby coding asap
