SketchUp have problems creating faces that are smaller than one square millimeter.
It has no problem Showing already created small faces though.
The solution is to make a component and copy it and resizing the copy. After that you model in the enlarged copy and you will se the correct result in the original component.
At last years SketchUp basecamp in London Felix Heuman & Anders Lyhagen showed how they created classic architecture in extreme detail. They worked with columns that were 1 km high to get the level of detail they wanted.

I HAVE HAD THIS ERROR FOR A LONG TIME AND ITS DRIVING ME CRAZY: I end up having to save the file manually and keep changing the name. Autosave does it and "Save" does it. I am not on a network, running as admin, saving to "documents/xxx.

It started when I upgraded to Make 2017.

I generally wait for a period equivalent of the time it takes me to go to the toilet.....if it hasn't responded by then I'll go and get a drink or make a cup of coffee and maybe even make a light snack.....if it's still a no show I wait wait another 5 minutes or so....

....if that totals 15-20 minutes or so I generally lose patience and close it off and hope that most of it is still there when I reopen it.....!! 😆

For me it mostly happens when I import something like a large tree model, or if I have a complex shape using something like Shape Bender....although I will be more patient with Shape Bender because it generally comes good at some point, but sometimes it scares the crap out of me...!!

I share your frustration though, especially if it happens when you haven't saved before it 'hangs'.

Fortunately though, most often an 'autosave' will get me out of trouble more often than not...!!

I see that from time to time when I'm working on imported geometry - it appear to be some small inaccuracy issue which compound eventually to problematic inaccuracy.

Just a tip, lock the 2D template so you can't select it.

Sketchup does not subdivide the texture deliberately, it is only not capable to align the texture.

The only ways of texturing organic shapes in Sketchup is using projected texture (native), or using spherical or cylindrical projection (plugin UVTools 0.1).

There are also other ways of texturing, like this workaround or using another programm for uv-mapping (plugin UVTools 0.2)

I think the options will depend on which font you have selected.
