&ASPECT
Allows you to read or set the aspect ratio. The aspect ratio times the character size determines the character width.
There are individual text preferences for dimension main text, appended text, tolerance text and drafting aid text. The Write option for this GPA sets all of these preferences. The Read option can only return one of these preferences. It returns the last preference that was modified. For example, if the DIMPAR command is used to set the preferences from a Note, then the GPA returns the text preferences for drafting aid text. If the DIMPAR command is used to set the preferences from a dimension, then the GPA returns the text preferences for dimension main text.
