Re: [OpenSCAD] Big text with WRITE.SCAD
Have u tried the built-in text() module ? It does response to $fn.

There's also a write.scad version that is based on the text() builtin:

Note that that one still uses assign( ) and needs a lot of re-write.

Does there already exist the possibility to add center=true to centre the text? If not, I would find this immensely helpful.

There is halign and valign which work based on the font properties
(the sizes defined for the glyphs in the font file).
There's currently no center that's based on the generated mesh vertices.
For mesh based positioning, I think something more general might be
useful, like an align() or pos(). There's an (meanwhile quite old)
pull request on github which has a pos() implementation, but that's
embedded in a huge change with lots of other stuff.
Similar to hull() or minkowski() this would have the side effect of
forcing the mesh calculation up to that point in the object tree so
it would have quite some impact on preview performance.
ciao,
Torsten.
When I need to fit an arbitrary-sized piece of text, I use the resize() function to bound either the width or the length (not both, to preserve the aspect ratio) of text(valign=“center”,halign=“center,…) and (re)position accordingly.

Thanks Andrew and Torsten.
Torsten, how do I invoke halign and valign please?
Andrew, I will try your suggestion - as it’s the main way I use text, and the resizing function is also useful, I will try to make a utility module and post it back here...

I don't know how I missed that. Thanks Torsten.
