Sketchup support just informed me that One Drive is the culprit. So I moved the folder out of One Drive and sure enough - the thumbnails appeared. So, in a microsoft community forum, I asked if they plan to resolve the issue.

Microsoft forum says this:
"That is not a file type natively recognized by Windows, so the thumbnails will not be generated automatically, it may be best to contact the support for that Sketchup software about this, there may be a setting in that software that needs to be changed."

I know for a fact it used to work perfectly with windows - but maybe on older versions of either the app or the windows version.

AutoCAD thumbnails work.
Adobe PDF thumbnails work.
JPG thumbnails work.

I tried:
Confirming the skp icons are associated with sketchup application being the default program.
I only have skp 23 installed in the PC, older versions have been removed.
I reinstalled skp 23 using the repair option.
I confirmed "Never show thumbnails - only show icons" is unchecked in folder view options.

I was once able to display my collection of components (valves and stuff) as thumbnails vs. generic blue box sketchup icons. How can I make that happen again?

just figured it out. I have a clipping mask that is interfering.

What is preventing the scene from extending all the way to the bottom of the viewport?

still an issue

I booted up mu PC this morning and launched SKP only to be given a user agreement to accept followed by something like "trimble is having technical issues.....and i am not authorized for this device" followed by being asked to sign out and back in again followed by SKP opening but with all the non-native toolbars completely separated off the screen and the trays missing from the screen. Was I being singled out or were other users exposed to this? Zero problems with laptop, however.

Thanks TIG
Been there, done that.
option 1 - everything is set to default
option 2 - i have no "graphics properties" on my desktop when it's right clicked
option 3 - when i click nvidea in the tray, its control panel pops up. however, unlike the windowsclub screenshot, i have no ''nvidea settings'' listed in item 2. only "current color accuracy mode: enhanced" and an unchecked checkbox next to "override to reference mode"

and by the way, either i hallucinated when i thought i lightened the navy blue, or i never really fixed it. this subject may seem trivial to most users - but it really is a point of dismay.

this is not relative to a single monitor's dysfunction since it appears on the other three, of different mfg's, as well.

I fixed it but now other non skp elements of win 10 are poorly colored. Win 10 color settings are difficult to manage. And to the best of my knowledge there is no reset to default.

OK - I am not a big subfolders guy - but I do have some. I need to trash these folders because i am running out of storage and I hesitate to install my new 1TB M2 SSD because it may cause a disruption in current workflow. (because nothing ever goes smoothly)

It will not display images of SKP or LO files. It works for other files though.

Despite uninstalling old versions of SU, there still remains 500mb worth of folders in c / users / appdata / roaming / sketchup . Is it safe to delete them?

Might the navy blue color obscuring the status icon in my layers/ tags panel have anything to do with the color scheme of my windows PC?

I turned LO off and on again and the VP remains functional. Is that what you meant, Box?

I cannot publish this company file. However, i restarted the PC and updated the reference and now the VP is NORMAL.

My viewport has no reaction to mouse clicks, despite the fact that other layout files linked to the same skp model work fine. Viewport layer is not locked. This particular LO file has been annotated in the past successfully and a PDF was generated. But it will not work now, even on a different PC. I can click the cursor all day on the VP with no reaction. Auto render box in properties is ticked. If I add a new VP to the page, linked to the same model, it works fine (the new VP). It must be something simple that I am overlooking, as usual.

Awesome! Thanks TIG

Can all tags listed in the Tags panel be selected and a common color be applied in one click....or must each tag be handled one at a time?

it was not corrected in 22
