CDF Default Option Abbreviations

Options provide additional information for a code. For example, they indicate whether a point is the start or end of a polyline, define the width of a rectangle, or attach text to a point.

CDF supports two groups of options:

• Global Options (GLOBAL_OPTION)
• Extended Global Options (EXT_GLOBAL_OPTION)

A code can contain one Global Option and one or more Extended Global Options.

Every Global Option and Extended Global Option has a default abbreviation.

;============================================================================

; GLOBAL OPTIONS define how a measured point is interpreted 

;============================================================================

L = GLOBAL_OPTION(START)                                 ; Abbreviation for start of line (left)

R = GLOBAL_OPTION(END)                                    ; Abbreviation for end of line (right)

A = GLOBAL_OPTION(ARC)                                    ; Abbreviation for point of arc

Y = GLOBAL_OPTION(END_ARC)                            ; Abbreviation for end of arc 

U = GLOBAL_OPTION(CURVE)                                ; Abbreviation for point of a curve (spline)

D = GLOBAL_OPTION(PERPENDICULAR_LEFT)       ; Abbreviation for Perpendicular Line left

E = GLOBAL_OPTION(PERPENDICULAR_RIGHT)     ; Abbreviation for Perpendicular Line right

C = GLOBAL_OPTION (CLOSE))                                ; Abbreviation for Close Polyline

P = GLOBAL_OPTION(PARALLEL_POLYLINE)           ; Abbreviation for a complete parallel polyline

Z = GLOBAL_OPTION(EXTRA_LINE)                        ; Abbreviation for a non-perpendicular line

/ = GLOBAL_OPTION(CODE_SEPARATOR)                ; Code separator to assign multiple codes to 1 point

I = GLOBAL_OPTION(INVISIBLE_ANGLE)                 ; Abbreviation for an invisible right angle

K = GLOBAL_OPTION(ANGLE)                                ; Abbreviation for an extra right angle

X = GLOBAL_OPTION(SYMBOL_DIRECTION )        ; Abbreviation for a point used to orient (rotate) a symbol

M = GLOBAL_OPTION(2D_MEASURING)  ; Assign a unique abbreviation if you need a 2D point 

;============================================================================

; EXTENDED GLOBAL OPTIONS add extra information to a point 

;============================================================================

* = EXT_GLOBAL_OPTION(PARALLEL_LINE)

T = EXT_GLOBAL_OPTION(TEXT)

W = EXT_GLOBAL_OPTION(WIDTH)

V = EXT_GLOBAL_OPTION(ECCENTRIC(IN_LINE))

L = EXT_GLOBAL_OPTION(ECCENTRIC(PERPENDICULAR_LEFT))

R = EXT_GLOBAL_OPTION(ECCENTRIC(PERPENDICULAR_RIGHT))

H = EXT_GLOBAL_OPTION(HEIGHT_DIFFERENCE)

I = EXT_GLOBAL_OPTION(INVISIBLE_POINT)

S = EXT_GLOBAL_OPTION(SCALE)

RULES FOR CUSTOM ABBREVIATIONS

• If you redefine only part of the option abbreviations, make sure your custom abbreviations do not conflict with the default abbreviations of options that are not redefined.
  Example: do not assign D to another Global Option if it is already used for PERPENDICULAR_LEFT.
• Abbreviations must be unique within the Global Options group.
• Abbreviations must be unique within the Extended Global Options group.
• The same abbreviation may be used once in each group.
• To avoid conflicts, it is recommended to define the complete set of Global Options and Extended Global Options in your CDF.
