This is only tangentially related and doesn’t address getting SketchUp Make 2017 working on MacOS Catalina, but there isn’t a high bandwidth overhead with SketchUp for Web. It will download the app once and it’s then cached locally and performs most operations locally. While this doesn’t address ease of use or the fact that the web version will take some adjustments to get used to, at least you don’t need to worry that it’s eating your data.

you can try installing with ‘Allow apps downloaded from > Anywhere’ and then go to Applications/Sketchup 2017 >> rightClick >> Open >> Open…
you can then turn security back to what it was…

Upgraded to Catalina to use Sidecar. Sketchup kills my laptop battery, when I close the laptop, Sketchup continues to draw 90% CPU and 60% memory resources.
That’s interesting. Are you viewing that on your iPad using sidecar?
Right, with Sidecar I can share or extend my screen from my 2018 MacBook Pro running Catalina.
My 3DConnexion Space Wizard doesn’t work, I’ll add. Space Wizard users are going ballistic that the drivers haven’t been updated yet.
Sounds like for some reason SketchUp is beating itself to death talking to the iPad via Sidecar. I don’t have a new enough iPad to try that, but it sure sounds like a glitch in either the Sidecar implementation (maybe involving Apple’s distaste for OpenGL) or in SketchUp!
My Space Navigator is working fine under Catalina so far (though I did need to reinstall the driver), but it is a simpler device than you are using. 3D Connexion has a very bad track record of not addressing issues on Mac in a timely manner or sometimes not at all. Years after it was first widely reported, I can still cause the runaway memory leak issue if I don’t take precautions when launching SketchUp.
Which version of SketchUp are you using?
Sidecar is only supported for Macbook’s of 2016 and later, so you would need a new MBP, too!
waiting to see what the rumored 16 inch MBP really is!

I agree… very sad that they decided to shrink their laptops!
The drain on the battery happens while Sketchup is open, with or without Sidecar connected iPad —FYI.
Also, the Trimble Connect extension issue seems to resurrected itself. I successfully rid my computer of it. But now I get a prompt to update the extension, but when I do it’s never successful. I’ve uninstalled. Deleted the extension from the hidden Library file. Disabled. Restart. But every time the Sketchup starts, it recreates the Trimble Connect extension folder in my Library.
Most recent version of Sketchup 2019. I manually check for Sketchup updates often.
My mistake, I have the Space Navigator as well. Will try reinstalling the driver.
RE, Trimble Connect. You cannot uninstall it. It has problems updating via the Extension Manager.
Go the the EW, and get it’s latest RBZ download. Install it manually via the button on the bottom of the Extension Manager. Restart SketchUp. Then switch OFF the Trimble Connect extension in the Extension Manager so it does not load.
From then on when new versions come out, they should update okay via the Extension Manager. Just update and switch it back off if updating switches it on. There’s no sense fighting against it. It is part of the SketchUp distribution.
Thanks, Uninstalling the 3D Connexion driver then Reinstalling worked for me!
thanks Jody, appreciate the Headsup.
I have downloaded Catalina (bad mistake on my part) and running the latest SketchUp 19.3 and layout is not working properly. unable to go back if you make a mistake and inserted items greyed out when exported to PDF. Also no plugin available from Artlantis for this version of SketchUp
I was so upset when I updated my late 2015 MPB to find it didn’t work with my iPad Pro 
Is it safe to upgrade my iMac from Mojave to Catalina AND to upgrade the latest SketchUp version?
