Hi there. In the 2023 version it was possible to scale a group/component and the dimension inside the group/component would update by itself. This is not the case with 2024.
Anyone who knows a workaround or if it will be patched?
If at some time you have done something with the text (typing a change or something) of the dimension then from that point on the dimension’s text will not be associated with the true length anymore.
You can restore that true value again by replacing it with <>
If you explode the group/component, the dimensions are updated again.
If you use these scaled dimensions in a plugin (like I do), just add the group with the scaled dimension into a new group and explode the original group.
Or, if you enter the group with the scaled dimension, its updated again.
Or, if you save your file, its updated as well. This last one is the most easy solution to this problem - just do a quick cntr-S after you have scaled some dimensions
I need the dimensions inside of the group in Sketchup. I make many 2d lighting designs and use Layout as little as possible. I am using the desktop Pro version.
The issue when exploding the component, it is not automaticly counted for when I make an overall count/legend. If I have several copies of one component, it is not updated when saving/opening it…
It is really a deal breaker (likely only for a few) but still…
Are you doing this in a plugin you wrote yourself? If so, it works for me like this. In my own plugin, I add a component with a 1m long dimension into a dimension group (with many dimensions), the component is scaled and immediately afterwards the component is exploded. This leaves me the right dimensions in the dimension group.
I receive the 2D plans as DWG and add the lighting tracks 1m, 2m, 3m, 4m (in several colours) on top as a layer and a second layer with luminaries.
9 of 10 times the design does not require a 3D drawing so I can make it quite fast this way - I have not found a faster way so far.
When my design contains 20 pcs. of the 3m track, some of them might have to be cut to lenght on-site, meaning I still need it to show up in the components count but the lenght/dimension would be shorter.
Everything is native and never use plugins. I am not sure how to to be honest…
I don’t really understand how you’re getting this to work?
It works for me because I explode the scaled component with the dimension. At that moment, the dimension gets updated
hello, I bumped into this issue too
I often add dimensions into groups to quickly and visually resize them, such as staircases while designing. I noticed that unlike previous versions, dimensions are not live updated in 2024. You have to edit the group or the component to update them.
It can lead to many design mistakes.
2022 behaviour
2024 behaviour
I see that too. I will check if it’s a known issue, and if it isn’t I’ll create a new bug report for it.
Work around for now would be to use the classic graphics engine.

I wonder… Has this bug been fixed in Sketchup 2026?
I was using Sketchup 2023 all along, and was just upgraded to Sketchup 2025 last week. So I’m runnig in this issue only now.
Here is a practical exemple:
Every columns are a different size, but the dimensions indicate 1599mm for all of them.
Here is the same scene open in SU2023 and SU2025
Sketchup 2023 (all the dimensions are accurate):
Sketchup 2025 (all the dimensions indicate 1599mm):
As Colin mentionned, reverting SU 2025 to the classic graphics engine fix it.
But how does SU 2026 deals with that?
That said, I must be missing something again…
If the problem has apparently been there since SU2024, I’m suprised this topic didn’t pickup more steam. It feels like a major problem that should concern tons of people, no? With all the liability that comes with providing dimensions, It’s hard to imagine that this issue would remain unadressed for years.
Or please tell me I’m dumb and I just messed something up.
I join the file here, in case it is of any use.

I opened your file in SU2026 and each dimension is different as appropriate.
TBH I haven’t seen that a lot of users have had this problem but I can guess what might be a culprit. That is you’ve scaled each instance of the same component to make each the different lengths so the length on screen doesn’t match the definition. And with the dimension inside the component it might be displaying the definition’s length instead of the scaled length. That’s just a guess, though.
I’ve found that other users have created problems for themselves by using this practice of scaling components instead of scaling the geometry inside.
In any case, it looks like 2026 displays the dimensions correctly.

Thanks a lot Dave!
That was fast!!
And that’s great news, a simple version update will do the trick!!
Indeed these dimensions only become non-responsive when they are inside a scaled component.
This column is a dynamic component though, and its automatic vertical scaling is really what makes its entire purpose. Scaling the raw geometry would probably mean making each instance unique, and scaling each column individually.
That would negate the interest of that component, so I’m glad I won`t have to resort to that.
Do get produce material takes offs with your models? I was never able to get you accurate materials take offs with scaled (dynamic) components. Maybe I’ll have to try again if it’s working properly now.
Material takes offs is the quantity of material used ? What do you use to obtain these?
I sometimes do that with “report on areas” from FredoTools.
After scaling these two dynamic conponents to different heights, it gives me an updated material surface area. And it matches Sketchup’s surface calculation, so it seems accurate.
