Since hatches can only do STRAIGHT LINES and by "Spanish style tile" I
assume you mean 'barrel tiles' which are
curved the best you are going to get is "sorta close".
In these cases, which thankfully are few and far between, I draw a tile and
array it and then trim. I have even done
this for elevations oblique to the projection. (Oi my head!) It's impressive
only to other CAD jockeys. If you want it, go to my site and email me.
