One of the big things for signage is multi-layer V carves. For folks who don’t have a BitSetter, here’s how to do them:
and Fenrus did some instructions on this as well:
and for folks who are fully up-to-date:
A further consideration is text and the setting of text.
There are a couple of characters which have subtle differences in how they are typed vs. how they should actually be typeset. Some notes/links on this at:
" '* (uni-directional stick quotes — ignore the extra asterisk, it had to be added to keep the forum software from changing these to curly quotes automatically) These should be replaced by the correct characters: “ ” ‘ ’ curly quotes
’ an apostrophe — ′ ″ or double and single prime marks (used when indicating feet, inches, or degrees; minutes and seconds)
X or x (to indicate multiplication or orthogonal dimension) Please use the symbol: ×
hyphen (-) often used to indicate not just hyphenation but also duration (en dash), a break in thought (em dash), or subtraction (minus symbol), additional code points are available for non-breaking and discretionary hyphens
– en dash
— em dash
− minus sign
If you’re using any special characters, I’d recommend looking them up at least in a dictionary to determine what they are and how they should be represented.
