Synopsis

obj = FMPOS/(origin),NONE{,SYMBOL,number|'text'|NEXTL}+

obj = FMPOS/(origin),{EXT,{1|2|3|4},line[,VIEW,'View Name']{,SYMBOL,number|'text''NEXTL}+

obj = FMPOS/(origin),LEADER,[{LEFT|RIGHT},]{obj1[,VIEW,'View Name'][,(origin)]|(origin)[,TRIANG]}{,SYMBOL,number|'text'|NEXTL}+

Description

Creates any one of fourteen available Form-Positional Tolerance Symbols.

There are three forms of the statement in the FORMAT below. The first statement creates a tolerance symbol with NO leader or extension line.

The second statement creates a tolerance symbol WITH and extension line.

The third statement creates a tolerance symbol with a leader.

The REQUIRED and OPTIONAL INPUT specifications are applicable to each statement based on which fields are used.

Parameters

Parameter

Description

(origin)

The text location. For the methods of specification, see Defining the Origin.

NONE

Minor word that indicates that the symbol is to be created without an extension or leader line. This feature is necessary when more than one symbol share the same leader line.

EXT

Minor word that indicates that the symbol is to be created with an extension line starting at one of the four corners of the symbol and terminating on a vertical line.

1,2,3,4

An integer which represents one of the four corners of the symbol.

1 - Upper Left
2 - Upper Right
3 - Lower Left
4 - Lower Right

line

An existing line or linear edge at which the extension line terminates.

LEADER

Minor word that indicates that the symbol is to be created with a leader line.

LEFT,RIGHT

The optional leader line orientation parameters. See the beginning of this section for a detailed explanation.

obj1

An existing object at which the leader line may terminate. The object must be a point, line, arc, conic, or spline.

NOTE: Form and positional tolerance symbols are associative objects, therefore, if the object specified for the leader line termination is deleted, both objects are deleted.

VIEW

Minor word that indicates that a view name is to follow.

'View Name'

This is a string variable or literal that is the view name.

(origin)

If an object is specified for the leader line, the end position of the leader may be controlled by specifying a position, nearest the point on the object, where the leader line terminates. If a position is not specified, the leader line terminates at a point on the object nearest the origin of the text. See the beginning of this section for the methods of specification.

(origin)

If an object is not specified for the leader line, a position must be specified at which the leader line terminates. See the beginning of this section for the methods of specification.

TRIANG

Minor word that indicates that the standard arrowhead is to be replaced by the INTERNATIONAL STANDARDS ORGANIZATION (I.S.O.) base triangle. This option is only valid for lines and arcs.

SYMBOL

Minor word that indicates that the next parameter is an integer representing a form and positional tolerance symbol.

number

An integer which represents one of the15 form and positional tolerance symbols listed below.

1 – Straightness
2 – Flatness
3 – Circularity
4 – Cylindricity
5 – Profile of Line
6 – Profile of Surface
7 – Angularity
8 – Perpendicularity
9 – Parallelism
10 – Position
11 – Concentricity
12 – Symmetry
13 – Circular Runout
14 – Rectangularity
15 – Total Runout

'text'

Text may be placed in the box instead of a form and positional tolerances symbol. In the text portion of the statement, however, some rules apply to the use of angle brackets. Angle brackets are allowed only when they contain one of the five special control characters listed below.

M – Maximum material condition
S – Regardless of feature size
P – Projected tolerance zone
O – Diameter symbol
E – Least material condition

NEXTL

The NEXTL feature controls which line the symbol or text is placed on. Entering NEXTL causes the next text or symbol in the statement to be placed on the next line.

Parameter	Description
(origin)	The text location. For the methods of specification, see Defining the Origin.
NONE	Minor word that indicates that the symbol is to be created without an extension or leader line. This feature is necessary when more than one symbol share the same leader line.
EXT	Minor word that indicates that the symbol is to be created with an extension line starting at one of the four corners of the symbol and terminating on a vertical line.
1,2,3,4	An integer which represents one of the four corners of the symbol. 1 - Upper Left 2 - Upper Right 3 - Lower Left 4 - Lower Right
line	An existing line or linear edge at which the extension line terminates.
LEADER	Minor word that indicates that the symbol is to be created with a leader line.
LEFT,RIGHT	The optional leader line orientation parameters. See the beginning of this section for a detailed explanation.
obj1	An existing object at which the leader line may terminate. The object must be a point, line, arc, conic, or spline. NOTE: Form and positional tolerance symbols are associative objects, therefore, if the object specified for the leader line termination is deleted, both objects are deleted.
VIEW	Minor word that indicates that a view name is to follow.
'View Name'	This is a string variable or literal that is the view name.
(origin)	If an object is specified for the leader line, the end position of the leader may be controlled by specifying a position, nearest the point on the object, where the leader line terminates. If a position is not specified, the leader line terminates at a point on the object nearest the origin of the text. See the beginning of this section for the methods of specification.
(origin)	If an object is not specified for the leader line, a position must be specified at which the leader line terminates. See the beginning of this section for the methods of specification.
TRIANG	Minor word that indicates that the standard arrowhead is to be replaced by the INTERNATIONAL STANDARDS ORGANIZATION (I.S.O.) base triangle. This option is only valid for lines and arcs.

NEXTL	The NEXTL feature controls which line the symbol or text is placed on. Entering NEXTL causes the next text or symbol in the statement to be placed on the next line.
