All but 1 of the 1/4-20 x 1 1/4" … are various diameter and length rods textured to look like screw threads. I’ve included one of the rods, they are all scaled up from inches to meters (M).
Could you explain a b it more about the problem that we should see in your screenshots?
The only thing I see is that Windows alphabetizes your component list slightly differently from SketchUp and that both agree that a space lists first, before any number, and that Windows has some number recognition (#10 is placed after #6) while SketchUp sorts one character at a time.
I always thought the component list was the actual title of the file where the component resides. 1/4 is an illegal fine name and it seems none of the threaded rods are in the SU components list. The components list is named BOLTS _NUTS, ETC, the folder name is BOLTS & NUTS, ETC
You seem to have a lot of file names with characters that generally should be avoided. Not all of these are strictly forbidden so I don’t know if they are the problem but…
Since my system is Windows 10, I know all the illegal/forbidden characters for my system - if Sketchup has a list of characters that are forbidden I would certainly like to see it.
An & is best avoided in certain contexts on Windows.
some spaces <>*/:&(){}^=;!'+,`"%~@
etc are best avoided…
They will work within SketchUp, and when exporting files etc some might work in file names, but in the file ‘processing’ done in complex apps they might cause an issue down the line, so they get swapped out as _
They can be ‘escaped’ but it’s PITA.
On a MAC the list is similar but not exact…
