Datacad does support Open Fonts. They are basically TTF's Neil. If you open your C:\Windows\Fonts folder you should see some fonts with a
O instead of a
TT on the icons. I've never really looked to what the difference is. Here is what Wikipedia says:
Wikipedia wrote:OpenType is a scalable format for computer fonts (also sometimes known interchangeably as "typefaces"), initially developed by Microsoft, later joined by Adobe Systems. OpenType was first announced in 1996, with a significant number of OpenType fonts starting to ship in 2000–2001. Adobe completed conversion of its entire font library to OpenType around the end of 2002. As of early 2005, there were around 10,000 fonts available in OpenType format, with Adobe's library making up under a third of the total. As of 2006, every major font foundry and many minor ones were developing fonts in OpenType format.
History
OpenType is intended by Microsoft and Adobe to be the successor to the TrueType font format which was developed by Apple Computer and licensed by Microsoft, and the Type 1 ("PostScript") font format developed by Adobe.
Microsoft tried to license Apple's advanced typography technology, "GX Typography," in the early 1990s, and upon being refused developed its own technology, dubbed "TrueType Open," in 1994. [1] Adobe joined Microsoft in 1996, adding support for the type of outlines used in its Type 1 fonts, and the name OpenType was then used for the combined technologies.
Adobe and Microsoft continued to develop and refine OpenType over the next decade. Then, in late 2005, OpenType began the process of becoming an open standard under the International Organisation for Standardization (ISO), under the MPEG group which had previously adopted OpenType by reference. The new standard is essentially OpenType 1.4, with appropriate language changes for ISO, and is called the "Open Font Format." The initial adoption of the new standard was completed in March 2007, when OpenType became ISO Standard ISO/IEC 14496-22 [2].
