Retention of dimension

Here is a new one. I have been using Sketchup since version 5 when it was owned by atLast. Ever since then a feature that was built into the software was that when I am using the tape measure tool to layout guidelines and such if there was a contact dimension that I wanted to use it would retain the last one I entered for re-use over and over. I am using the latest version of 2026 on a MacBook Pro. I have noticed that the feature is no longer working and I cannot find anything in settings or customization that allows me to make a change to have it work.

Anyone have any suggestions?

I’m not sure what you mean by a ā€œcontact dimensionā€. Is it possible you are thinking of using Move/Copy to make an array of guidelines?

Please update your forum profile. It says you’re using SketchUp 2022.

No../.what I meant was that if I am using the tape measure tool and want to keep using the same dimension over and over to cast a bunch of guidelines. The software used to retain the previously entered dimension and would use the last entered dimension until it was changed.

I think I know what you’re talking about. At this moment I can only demonstrate this on SU2021, so I’m not sure if it’s the same in newer versions…
Edited: I checked in SU2017Make and SU2026; works in a same way, so I assuming it was always like that.


There is a so called ā€œlast length snappingā€ feature (which is independent of whether ā€œEnable length snappingā€ is selected in the Model Info Units menu).

This means that if you use one of the Tools (Line, Circle, Arc, Move…Tape Measure*), the ā€œsystemā€ remembers the last dimension entered, and the next time you move the mouse, the cursor snaps to that last dimension.
This is independent of which Tool you are using, so if you entered a dimension in the Line Tool and for example you switch to the Circle tool, the Circle radius will snap to the dimension entered in the Line tool.
If you switch to the Tape Measure tool, it will also use the value entered in the Line tool.
Like this:
lastlensnapa

*However, for some reason, when you create a parallel guide line from an edge or another guideline in the Tape Measure tool, the entered size is not recorded:
lastlensnapb

The workaround is to create a Guide point by entering the distance, then the parallel Guide Line will be able to use the distance you entered when creating the Guide point.
lastlensnapc

(Or, for example, as you see in first animation, you can temporally switch to the Line tool, create a line, enter its size, delete the line, and switch to Tape and you can use the value entered in the Line tool…)

I tried all of your suggestions and it is still not working at all. I really need this feature to work.

How to create guide lines with a fixed distance using the move copy tool, also move guide lines using the stamp tool to place then to whatever distanc you want to put them without lifting the mouse.

Hey DaveR…

I recall that in previous years release that if you were using the tape measure tool and plugged in a dimension of 10’ or whatever, the next time you used the tool or if you wanted to run off a series of ā€˜guidelines’ that it the app retained your last inputted dimension so you could keep running guidelines in any direction at the ā€˜retained’ and previously inputted dimensions.

I saw your early comment about that. I don’t have an earlier version to test that so I can’t say either way.

TBH it wouldn’t have occurred to me to make an array of guidelines that way. It would be simpler and faster to just create the array with Move/Copy.
array

well, I just tried what Dezmo said, and it still works that way.
I can’t remember if it used to work with parallel guides too, or only drawing tools (I’ve only used it while drawing), but it kinda works.

Depending on the situation, this could be a request for a bugfix (if it used to work and doesn’t) or a feature request :wink:

I know exactly what you mean — I use that feature all the time when setting out guidelines.

For example, I might create four guide lines at 20mm, but only enter the dimension once for the first guideline. Then I switch to 5mm and again only enter it once before laying out several more guides.

I’m currently using SketchUp Pro 2025 on a PC, length snapping is always switched OFF and it still works that way for me.

Hope that helps :+1:

Yes it still works for me too. Maybe a Mac specific bug for OP?

I just confirmed on 2026 on Mac, @dezmo’s workflow works, as well.
