Strange dots on Sketchup 2026 line tool

SketchUp Pro
1

Hello everyone. Just today I encountered an odd behavior of the line tool. If I draw a line anywhere on the page (not in Layout) then click off to draw another line or just escape the tool, evenly spaced short dashes or dots appear. (see attached screenshot). I’ve been using v2026 since it’s release and have applied the latest update. These are not actual divisions. If I drag my mouse over the line with the line tool, it doesn’t try to snap on one of these, so they’re superficial and not actual geometry. To clear them I have to select one of the lines then deselect so the dots disappear. Really weird. This has not happened before. Btw, it didn’t start immediately after applying the latest update several days ago.

Thank you for taking a look at this.

Can you share a simple file with some edges that show the dots so we can look at it on different hardware?

Is it possible that you have an extension that can style edges that way? Possibly some overlay thing?

Possibly something from a divide tool? Fredo divide maybe?

Here’s a file. I don’t think it will reveal anything though. Even if I disable all third party extensions, it still happens, so it’s not an extension. You cannot snap to these as you can actual divisions. They are superficial.

Well apparently I missed disabling one of the addon extensions. I went back and stripped all the third party ext. and now the problem is non existent. Sorry to trouble you guys. Thanks for your input. I truly appreciate it.

I don’t see the file.

Do you know yet what extension it was? Might be useful to know in case someone else has the same issue.

FWIW, Fredo6’s Divide extension would place guidepoints at the divisions or actually divide the edge so either way you would get something to snap to.

Hello Dave. Sorry for the late response. The rest of my day was hectic yesterday. The extension is Model Doctor which scans for geometry issues. One of the scans is ‘Cleanup: loose lines, extra lines, tiny geometry, small gaps, unused items, performance’. So the offender looks like me, because I didn’t fully understand the functions yet :slightly_smiling_face: .

So, basically problem solved. Thank you both for your efforts.

Charlie-

Thanks for that reply. I’m not familiar with that extension. If I understand what you are describing. The edge is marked with those orange dots because the extension sees it as a stray because it’s not connected to other edges and supporting a face or two? If so, that’s interesting although I’d think it a bit annoying to see while modeling.

Anyway, you learned something and the problem is past history so all good to go.

Well said Dave. If you’re in the midst of constructing something, it would be annoying. The good thing is you can toggle the scan on/off. There’s a button on the toolbar.
