Editing Dimension Lines

Is it possible to change the Dimension Lines of the Dimensions meassured in the drawing? For example, I would like the line which refers to a certain point to be just a short line and not a line which visually reaches all the way to the point measured. These lines make the drawing less clear (to many lines in the drawing itself).

I can’t find any options to change that in Dimension Style. The only way to get rid of the lines is to manually change them by double clicking on the measured line and changing the line with the blue dot. Hope there is a quicker solution to style your LayOut drawing.

Something like this?


I think the OP covered that in his last paragraph, didn’t he? He ie probably thinking of the kind of options you get in Autocad that allows you to alter things like line offsets globally.

Exactly that, but then I would like it to be a Dimension Style, so I won’t have to change the distance manually with each dimension.

It is also possible to use the Eye Drop tool, but then the distance the line is shortened is applied. So the end result is still not as tight as needed.

Here you see the end result I would like to have. But if you look closely, you can see that the lines are adjusted manually as they are not exactly alined.


This is the (one of the) standard outcome when using Dimension Styles. The lines are for me disturbing. Hope the problem is clear now.

Can anybody help me out, or is this just the way it has to be done (I refer to manually adjusting)? And if so, does anybody now a quick way to change all the dimension lines as shown in the above picture (first I uploaded)? The result I got costd me a lot of time. Using the sampler, the lines were exactly shortened as the ‘host’ line, and not all lines have the same lenght which resulted in a drawing with the dimension lines not lined up properly as required. Hope someone can help me out.

Chris, in your gif, how do you restrain the extension line in one plane when altering its length? I can’t find any way to do this - whenever I do this it will move off centre, losing the actual dimension. Dimensioning was a lot easier in LO2016, now its a lesson in frustration in SO 2018. Why can’t I move the dimension line in either direction anymore along the extension lines - it seems to be fixed for one direction only? Happy to be told I’m missing something.

I hope someone can help out. I don’t understand why there is no reply anymore. I value the comments of @DaveR a lot, but he pulled out of the discussion. All I need is a Dimension Style which automates the changes shown in the GIF of @ChrisDizon. It seems so obvious that this must be possible, but maybe I’m wrong about this. Hope someone can give a proper explanation. Thanks in advance!

It is possible . Put a request in the Sketchup section under Feature request.


If you want the change to the dimension to be a default for ALL your further work, you should make the modifications to one dimension and then set it for the dimension tool itself. From there, create a template that you can use on other projects.

Alternatively, you can create a template with all the different styled dimensions you might use. Have them placed away from the project sheet and sample them as needed.
(See the gif below)


… and yet another option would be to have all your styled dimensions set up in a scrapbook. When needed, drag the styled dimensions into the project and then sample like the example above.

An Update on my above Scrapbook idea.

You don’t need to drag the styled dimensions into your doc. Instead directly sample the style dimensions from the scrapbook itself!!

Hi there,
I am still learning SketchUp and Layout but also having trouble with editing the length of extension lines when dimensioning floorplans and elevations. Up until last week, I was able to adjust the gap length and all extension lines came out the same length. I have downloaded the latest Layout update and suddenly the gap length adjustment has disappeared.
Any way to get them back or change settings on extension line length so they remain the same?


Further to above post, here is what my Dimension Style box looks like now.
The Extension Lines adjustment at the bottom are just no longer there. Is there a way to get them back?
Having to manually adjust the length of each extension line is ridiculously time consuming!

I’ve been using LayOut for years and I’ve never seen that first screen shot you show in any version through 2019. I wonder where that came from.

As for editing the extension lines, you can edit the gaps by selecting the extension line and dragging the dot like Chris shows in his first reply in this thread. Once you’ve set them for the first dimension, select the Dimension tool, hit S and sample that dimension to apply the setting to future dimensions you make in the project.

We added the ability to adjust Extension Line length in 2019.2 so that should be an option on the Dimension Style dialog. Because this was a minor version update your dialogs may need to be expanded to show the feature.

Oops. needed to expand the Dimensions panel. Maybe that’s @LearningSketchUp’s issue. Pull the bottom down.

Thank you @DaveR and @trent
I have tried your suggestion @DaveR but keep getting one end of the extension line longer. Do you need to re-sample it when you change the side of the diagram you are dimensioning? Ie, you sample for along the bottom, then you need to re-sample for along a side?
I am studying interior design and doing work for designers so there are loads of dimensions to be added into floorplans and elevations.
@trent please see attached screenshot. The little lines that allow you to expand the Dimension Style dialog is not there (you can see it in the Pattern Fill dialog below) - as per my circles in red.
I’m a bit stuck on this!!
Your help is greatly appreciated :slight_smile:
