SHAPE
Inserts a shape from a shape file that has been loaded using LOAD.
Create Shape Definition Files
AutoCAD for Mac font and shape files (SHX) are compiled from shape
definition files (SHP). You can create or modify shape definition files with a
text editor or word processor that saves files in ASCII format.
Shape Descriptions
AutoCAD for Mac font and shape files (SHX) are compiled from shape
definition files (SHP). You can create or modify shape definition files with a
text editor or word processor that saves files in ASCII format.
The syntax of the shape description for each shape or character is the same
regardless of the final use (shape or font) for that shape description. If a shape
definition file is to be used as a font file, the first entry in the file describes
the font itself rather than a shape within the file. If this initial entry describes
a shape, the file is used as a shape file.
Being able to create your own shape definitions is a valuable skill. Keep in
mind, however, that this is a very complex subject to learn and requires
patience.
Each line in a shape definition file can contain up to 128 characters. Longer
lines cannot be compiled. Because AutoCAD for Mac ignores blank lines and
text to the right of a semicolon, you can embed comments in shape definition
files.
Each shape description has a header line of the following form and is followed
by one or more lines containing specification bytes, separated by commas and
terminated by a 0.
*shapenumber,defbytes,shapename
specbyte1,specbyte2,specbyte3,...,0
The following list describes the fields of a shape description:
shapenumber A number, unique to the file, between 1 and 258 (and up to
32768 for Unicode fonts), and preceded by an asterisk (*). Non-Unicode font
files use the shape numbers 256, 257, and 258 for the symbolic identifiers
Degree_Sign, Plus_Or_Minus_Sign, and Diameter_Symbol. For Unicode fonts
these glyphs appear at the U+00B0, U+00B1, and U+2205 shape numbers and
are part of the “Latin Extended-A” subset.
