Alternative Character Set

Draw incorporates an alternative character set that provides useful symbols. An ‘alternative’ character is specified by preceding one of a set of normal alphanumeric characters by the tilde (~) sign. For example, the steelwork I-beam symbol can be defined as a TEXP by setting the BTEX attribute as:

BTEX ’~I’

The tilde can be input as normal text by doubling it (for example, ’~~’ produces a single tilde). Normal text, intelligent text and ‘alternative’ characters can be input in any combination.
