Easy way to fix difficult to find line/surface allignment issues?

Not too sure how to explain. But at times when I copy paste from different working files I sometimes find I have encountered an issue somewhere. Usually some wall is not alligned with an axis, but this will then always be a milimeter or so.

This then results in allignment issues with other faces, or push pull etc.

In complexer files, it is sometimes impossible or extremely hard to track down where the problem lies. Is there a feature, or extension available to track down which lines are not alligned to the axes? I can imagine an extension that shows in color which lines are not alligned.

Change the style in ‘Color by Axis’

hello, no need for an extension for that, go to the style panel and change to color by axis

Thank you both. Never knew about this option, but that’s it. So, the lines not showing color (black), are not on an axis. For future reference of other users encountering this question: it is helpful to turn of the model axes in the style as well.

Curious: still, with an extremely complex structure, it might be difficult to track that one black line. Is there no extension that helps with that?

Perhaps my file is faulty in itself. I could fix the issue in a certain wall, but one of the lines still showed as black. I drew the wall again and still some lines showed black.

I copied that group into a separate file, where the issue did not show and all was fine.

Any ideas what could be going on?

not that I know of, but what you can do is while keeping the “by axis” color parameter for edges, switch to wireframe mode and orbit (or choose the default iso view) so that you can see every edges.
optionnaly, if the model is too complex, you can export 2d view to PDF or dwg/dxf and use a 2d vector software to spot edge by color, even if very tiny

can you share the file ? (faulty one)

Colour by Axis has a Tolerance that makes tiny errors difficult to spot. Use the text tool to check vertices and see if they line up.
The usual reason for this sort of tiny error is having Length Snapping enabled in Units.
Best turned off in all templates.

Sure, I saved the file as a different file and deleted all lines that are ok, just keeping the group with the faulty line.

Very good input that colour by axis has a tolerance for tiny errors, thank you.

I have length snapping turned off and am still able to do the following:

Not to sure how I would use the text tool for checking the allignment?

I am now thinking it might have something to do with geo locating the file and changing the axis. This caused issues in 2024 with some axes allignment and perhaps this has not been corrected yet in 2025.

In my BlackLine file, I removed the geo location, but you can still see those faults when you for instance use the rotate function. you will see that the bleu plane does not show correctly

I can reproduce the issue, and you actually have 2 of them that aren’t recognized as aligned to red axe. If you move & copy in the very same model it randomly occurs, sometimes not, sometimes for one of them sometimes both.

I’ve noted absurdities in the inference system while working since (at least, cause I skipped 2023) 2024 version, but nobody seem to believe me :sweat_smile: , hard to prove, hard to reproduce as it looks random, I guess hard to fix too !

Thank you. Perhaps you can check when these faults occurred, if these happened in files where you geo located your model and changed the axes.

by using it on points to check coordinates, but it is irrelevant here as you changed axes and it sticks to real world coordinates

I ended up copying the faulty group and pasting it in a separate file that is not geo located. I then copied it back to the original file and everything is ok. Did not change a thing myself with the lines.

Perhaps I will log this as an issue with geo locating then.

Thank you all for your support.

I see we already had a chat about this Geolocate True North Offset issue - some tools default back to True North

but it’s more about the rotated axes to me

in your faulty file if you reset your axes and rotate your wall so that it’s once again aligned, no issue
