These are the file names of the SHX files included with BricsCAD: SHX Font File The gallery below illustrates the development of the letter Q, from the original Txt.shx to the more recent TimesRoman.ttf.ĭevelopment of the letter Q from the 1980s to today Eventually, Apple's TrueType font technology allowed for truly smooth looking and fully filled fonts, even in CAD drawings and on plots. The drawback to SHX-based shapes, however, is that they are not well-suited to defining the complex curves that truly represent fonts, nor can they be properly filled.Īs computers became faster over time, the number of lines used to draw characters increased. The simplest font of all, Txt.shx, looked ugly, but was able to draw most characters with just eight lines. To solve the problem of vector fonts taking a long time to display on the slow computers of the 1980s, Autodesk ® invented the SHX format: the simpler the font, the fewer the lines, the faster the display. Computers didn't have much horsepower, and text was one of the slowest parts of the drawing display.
In the early days of CAD, fonts were coded to be highly efficient. 00DīricsCAD uses shapes for fonts, the text in complex linetypes, and shapes. Multiple x,y displacments terminated with (0,0) code.Īrc defined by x,y displacement and bulge. 4 - third character specifies the direction of the vectorġ3Multiple bulge-specified arcs.
Vector codes define movement and drawing in 16 directions: Shape data consists of vector and instruction codes. NAME - names the shape must be in uppercase, and a maximum of 16 characters LINE 2: DATA Range is 1-255.Ħ - specifies the total number of data bytes. * (asterisk) - indicates the start of the shape definition.ġ30 - numbers the shape fonts use the character's ASCII number. The end of the data section is signified with a zero. A shape definition consists of at least two lines of text, a header that labels the shape or font, followed by one or more lines of data that describe the shape. shp files, which need to be compiled into.
