SketchUp 2021.1: A notable and noticeable update

Completely agree. I saw these “innovations” at a client this morning (under classic license). It is really an embarrassment to work, and I really do not see the point.


When I select Faces and view Entity Info, some faces are giving a negative value.

This applies on both front and back faces. I dont see any pattern why some would be + and some -.

When adding cumulative faces, this also applies so the added value is wrong.

If this is intentional (why would it be?) then it is a complete disaster for my work…!!!

error calc faces.skp (38.2 KB)

SKP model above may hold the key.

Eneroth Flatten Faces fixes the problem (i hope/trust, since i dont have a way of verifying what SKP is telling me the area is)

I’d say it is related to the Bowtie bug, this tiny triangle is causing the edges around the inner hole to be included in a double click selection of the face.
As an aside you have faces and edges tagged separately.

Ah, so it’s not related to 2021.1?
Thanks for looking.

…But it’s a pretty critical bug! This sort of error could mean all my property data is way wrong… $millions in investment which hinges on my plans and, if incorrect, i could be held liable!

Is there an official explanation on this “Bowtie bug”? (first I’ve heard that name).

PS the geometry on differnet tags is intentional (lineweights).

It’s one of those things we know about and keep pointing out to people in the team, but it never gets fixed.
Basically it is whenever you create a shape that attaches by one point it somehow sees it as two faces, or one face folded back on itself.

You can replicate it easily as you see in the gif, add another edge to split the face and it will behave properly.

The interesting thing is that this “update” is neither “good or bad”, its just different, and when you get used to working a certain way it really messes up your rhythm. Specifically, I’m VERY used to HOLDING down the ALT key when using the paint bucket to load in a material, but now I have to tap the alt key. If I now hold the ALT key down, it doesn’t properly load in the material. Its simply habit over 17 years of SU use that i now have to break. Similarly, the move/copy command. I get the “stickiness” idea, and in theory its great, but it is different then what I’m used to, so therefor really messes with my rhythm. None of these are inherently good or bad changes, they are just different, and different is disruptive, which is why I would love to be able to toggle this on/off. Just my 2 cents.


I sadly haven’t had much time to use the latest version myself but have used SketchUp extensively for 14 years or so so I know what you mean with habits and rhythms. Paint Bucket tool should have a dual pattern where both tapping and holding are supported. In theory this should be like the toggle you describe, except that you don’t need to toggle it, it should support both patterns out of the box.

What happens in detail when you hold Alt? If the behavior has changed it might be a bug.

As Christina suggests, I am able to hold down the alt key to load a material and also just tapping alt without any issues…

Thanks for breaking it down, Matt. When you are holding the Alt key to sample with Paint Bucket, are you seeing that the sampling (of the material) is sometimes working properly, or not at all?

I like the list because I was bought up in a Metric world and now have to work in Imperial so I can see all the scales available to me.

Love the update! But is there are way to turn of the sticky thing? Never needed this :frowning: .

Also, I can no longer create a new tag by typing it into the Entity Info box.

Please allow me to create new tags by typing them into the Entity Info box.

@nate2 read this thread:

It would seem to be best practice to implement new features/changes — that break workflows — as preferences that can be toggled between old and new behaviour.

Given that there will never be unanimity amongst users whether UI changes are improvements or impediments, this approach would elide the problem of newly-frustrated users (over their workflows being disturbed) while still allowing SU to evolve and try new things.


Ah I see. Thank you for leading me to the explanation.

As far as the sticky thing goes, I LIKE it. Maybe it should have a toggle, on or off.


Interesting remark.

But maybe if it takes an option to disconnect a new working option (which has not been requested?), It is proof that it is not good.

I don’t think it’s a matter of habit. Ergonomics is a subtle discipline. I would be curious to know what this decision was made on. For example, does this type of operation commonly exist in other software?


As a newby approaching my 1st birthday on pro would like to say that I like that extensions are now have their own ‘department’
Just like to add that I have always thought it a little odd that Model Info and Preferences is listed under Window rather than say File…but…whatever
Found Eneroths explanation in Who will win Extensions vs Plugins? - #8 by sjdorst useful…so I will stay with Add- On’s - HAHA

PPS have deleted my earlier comment within the above about extensions and tools as its…stupid ! db11 has advised you can choose where Fredos appear - ie tools or extensions. I need to investigate the issue further.

For any of Fredo6’s extensions you can choose which top menu they appear under (ie. ‘Tools’ or ‘Extensions’), and whether they appear individually or within a ‘Fredo6 Collection’ folder.
