Regarding SU older version install
Why stop at V2017 for plugins?
V2018 works for all the plugins I use both legacy extensions and paid for.
What is special to v2017 for plugins ???
Question does Trimble just kill the use of the older version going back as it is connected on line for the back version install and are just greedy enough to do so.??

I was replying to zx10r_Gaz who had extensions that wouldn't run in 2018. Why stop at 2017? I never said there was anything special about 2017. I'm using 2020 here. Any new version has the potential to break a plugin and if that plugin is really important to you, that might make you stay with the old SketchUp version to keep it working.

Not being able to reinstall older versions annoys me too. I had multiple versions installed going back to SketchUp 8 on my old computer. Now I've just got a new machine and I can only install 2020. I think they stop you reinstalling old versions to stop people selling their serial numbers for the older versions they no longer use.

One other bummer I found out about was when you upgraded to the newer version, you lost your licence for the version before. The reason this has pi**ed me off is I though 2015 and 2016 were the best versions as they worked with all my purchased plugins and favourite free one. My 2018 works with none of them. I wish I could give up my 2018 and 2017 licence and go back to 2016.

When you enter your serial number for a new version, you don't lose the licence for the old version. If it's still installed on your computer you can still use it. What you lose is the ability to reinstall it or install it on a new computer.

I'm sure there is a way to roll back your licence to an older version. I've seen people on the SketchUp forum getting this done for them. You'd lose the use of the 2018 of course, but it would let you reinstall one of the older ones. This isn't something you can do yourself. You'd have to get your reseller to help you.

Perhaps I’m being a bit daft but the below quote

“Please be advised: if you purchase a Classic Perpetual License or renew your Maintenance & Support license prior to November 4, 2020, you will not be able to upgrade and access additional features on that license every year as you have in the past.”

So say I got one last perpetual licence m&s in October - would that mean I’m unable to download any of the post nov 4th - 2020 version updates or 2021 version and 2021.1, 2020.2 updates and so forth for that last year of m&s. I’m having trouble deciding the above quote

The above quote is a bit ambiguous, but I think the 'every year' part is the important bit. You're supposed to get the full year of M&S including upgrades. After that runs out you won't be able to buy M&S again.

If you look at the FAQ this bit says you'll have M&S benefits for the full duration as normal (one last time).

Can I continue to use and renew my Maintenance & Support plan for my existing classic perpetual license?
Yes, you can renew your M & S support plan until November 4, 2020. as long as your M&S renewal date falls on or before that day.

You will have access to the M&S plan benefits, including Support, for the full duration of your M&S plan, even if those plans extend past Nov 4, 2020, but license plans expiring after Nov 4, 2020 cannot be renewed or extended.

My understanding is that if you renewed tomorrow, your M&S would run out on 15th June 2021 and you'd hopefully get version 2021 by then. The latest anyone could have active M&S would be 4th Nov 2021 (give or take a day) and after that no one would ever get an upgrade on their perpetual licence. I bet version 2022 won't be released until after that day.

I’m still using Adobe cs6 on the Mac and Mojave is the last OS X it will work with
I know that sketchup 2020 needs high Sierra or above to work so by that logic sketchup 2021 is last version to work with Mojave so there’d be no point me updating past this next version anyway

That's fine until your Mac dies and you buy a new one which will only run Catalina (or newer in the future). Then you'll be forced to buy or subscribe to newer versions.

I do question how smart this move is from Trimble esp in a post pandemic business world - many people won’t be able to afford subscription - sketchup is no adobe or autodeck

Not very smart as regards supporting the users that have supported them. It's made a lot of users angry, including myself. They probably think it's smart financially, weighing up how many people will be forced to stop using SketchUp against the numbers of users that subscribe at 2.5 times the price.
I don't want to stop using SketchUp, but I might have to move away from it in a few years.

The first time your nested i, j loop runs, i and j are both zero, so your radius will be zero as sin(0) = 0.

The add_circle method is called with:
add_circle([3.272727272727273, 3.272727272727273, 0], [0, 0, 1], 0.0, 24)
which has a radius of 0.0 so it will sort of fail and return 2 edges instead of 24. Then you won't be able to find faces when there's only 2 edges and you'll get the errors you saw.

I haven't used that code editor or read that book. The error is nothing to do with your editor. As I don't have access to the book I don't know which parts you've changed.

I'm not entirely sure what it's supposed to look like, but here's what I've got.

I put it all in a group so it doesn't stick to existing geometry. I just erase the failed groups where add_circle fails to form a circle with 24 segments. You could check for radius being 0.0 but there's also some cases where it's extremely small e.g. i=9, j=9 where the radius is 1.6e-16. I left in some of puts statements I had for debugging to let you see what's going on.

Docked

Click the folder icon, click Download then choose the version. Choose the oldest one (2017) so more people will be able to open it.

Push-pull will probably get stuck at the mitres.

There's more than one way of doing this. Here's one way. Draw a rectangle on the square end of one of your mouldings, so that it's perpendicular to the length. Draw your profile on that with the arc and delete the parts you don't need.

Draw 3 lines, one for each section. Select these lines, activate Follow Me, click on the face. It will form all 3 in one click.

If you share your SketchUp file here, we could show you how to do it on your model.

BoolTools2 isn't free, but it's only $20 and it works with Make. It works better than the solid tools in Pro anyway. It preserves components and works better when tiny faces are involved.

It looks like the previous chmod command worked:

I think you've made a bit of progress. You're now getting a different error from another program that probably doesn't have executable permissions either. Here's
one more command to make it run too:

chmod u+x ~/Library/Application\ Support/SketchUp\ 2018/SketchUp/Plugins/universal_importer/MeshLab/Mac/MacOS/meshlabserver

run that then try to do your import again. I think there might be other files on your system with the wrong permissions, but I'm only getting you to change one at a time here.

As I suspected, you don't have permission to run that file. You could fix it with another terminal command:

chmod u+x ~/Library/Application\ Support/SketchUp\ 2018/SketchUp/Plugins/universal_importer/Assimp/Mac/assimp

Be more careful copying and pasting this time. The 'CODE: SELECT ALL' link doesn't work for me, it just scrolls to the top of the page.
That command just changes the execute (run) permissions of that one file.

They are perfectly readable, but you don't have to screenshot the terminal, just copy the text as if it was any text document in a word processor or text editor.
