Qualifiers may be used to alter the way line pattern commands operate. Unless otherwise noted, qualifiers apply to one item (corresponding to one symbolization command) only.
A qualifier must follow the command it operates on. |
Qualifier | Description | Syntax |
|---|---|---|
/LWT | Line weight | /LWTn |
Assign the line weight, in inches, for one item (for example, a single symbol or dash) in a line pattern.
The line weight value applies to one item only; all other items will be assigned the default line weight. The /LWT qualifier must follow the item for which the line weight is to be changed.
The line weight in the master file record is in thousands of an of inch. The line weight specified using the /LWT qualifier must be given in inches. |
Qualifier | Description | Syntax |
|---|---|---|
/OFF | Offset | /OFFm.n |
This qualifier is used to:
• offset a dash, symbol, or arc by m.n inches, or
• squeeze the end points of a PASsed line by m.n inches.
The number m.n can be positive or negative, except when used in conjunction with the PAS command, when it must be positive. This qualifier must follow the item it is to act on. Positive offsets are to the left of the line being symbolized, when looking from the start to the end of the line. Negative offsets are to the right of the line being symbolized.
Qualifier | Description | Syntax |
|---|---|---|
/RAD | Radius | /RADm.n |
This qualifier is used to specify the radius, in inches, for arcs generated by the AG command. It must follow the arc generate (AG%) command. The specified radius must be positive. If you do not specify a radius, the distance from the current point to the next point on the line will be used.
Qualifier | Description | Syntax |
|---|---|---|
/ROT | Rotation | /ROTd.d |
/ROT allows individual rotation of dashes and symbols by d.d degrees. It must follow the item on which it is to act. Rotation may be positive or negative, but the effects are different:
• Positive rotation implies rotation with respect to the current line. This is called a relative rotation.
• Negative rotation implies rotation independent of the direction of the line. This is called absolute rotation. It is measured counter clockwise from the horizontal. A rotation of 0 is the same as specifying no rotation; the item will take on the orientation of the line. A rotation of -360 will keep the item upright regardless of the orientation of the line.
Qualifier | Description | Syntax |
|---|---|---|
/SIZ | Size | /SIZn |
The /SIZn qualifier sets the size of symbols:
• A negative integer is a magnification value.
• A positive real number is an absolute size in inches.
For symbols displayed on screen, /SIZ takes precedence over the magnification field in the master file.
Qualifier | Description | Syntax |
|---|---|---|
/UPR | Upright | /UPR |
The /UPR qualifier forces symbols to remain at a readable angle. Angles must be between 0 and 90 or 270 and 360 degrees.
Other rotation factors are taken into account, then, if a symbol angle is greater than 90 and less than 270 degrees the symbol is rotated by an additional 180 degrees.
