Is it correct that these are not taken into account while rendering at
the moment?

I assume doing that would be the scope of
<https://wiki.documentfoundation.org/Development/Budget2022#3D_rotation_of_Impress_shapes>.

But if that's true, then we don't really map LibreOffice's 3D objects to
MSO formats in general, am I right?

So would that mean fontwork is the only case where we currently import a
shape from MSO formats and that results in a 3D object on our side?

I hope once these are clear, we can discuss the individual properties
more easily. :-)

Somewhat related, if you have some RTF document where these properties
are not imported, but the DOC version of it is imported correctly, I
would be interested to look at that -- could you please file a bug and
CC me?

Thanks,
