Playing with spiral stairs, it is very hard to draft steps that are not standard paper's 2, 5 or 10º.

But, I found a site that does custom increments, on a wide choice of page sizes, as free PDF...

I've just dialled up 20º spokes, 5 rings (representing 2', 4', 6', 8' & 10' feet) and an open centre for least clutter.
FWIW, this facility may also be handy as a 'reality check' when laying out arches...

They also do traditional 'squared' format and a zoo of other stuff...

Thanks for HU

The server was misbehaving; I've several duplicate posts. How do i delete them ?

All I can find is the 'edit' without 'delete'...

Should be all cleaned up now

Thank you !!

I've just discovered my HP series A3 networked printer will no longer talk to Windows 10. Downloaded enormous new driver pack, went through everything, ran a test page, fine.

But print a document ? Forget it !!

Un-install, re-install, does everything but actually print a document....

Rinse & repeat, still no document printing...

Enough is enough. It is headed for the re-cycle. A new all-in-one printer with an A3 scan bed, a document feeder and DUAL paper trays is arriving next week...
