Synopsis

obj = LDIM/{HORIZ|VERT},(origin),[{ENDOF|CENTER|TANTO},]"PMOD3",obj1,[VIEW,'View Name',][{ENDOF|CENTER|TANTO},]"PMOD3",obj2[,VIEW,'View Name'][,Dim. text][,APPEND,App. text][,OBLIQ, Angle]

Description

Creates a horizontal or vertical dimension based on which minor word is specified between two previously defined objects. Positional modifiers are used for each object to specify which end of the object should be dimensioned.

You may also override the dimension text by placing a string in the proper field. Text may be appended to the dimension. The placement of the appended text may be controlled by the global parameter &APSITE.

The extension lines of the dimension may be created at an angle measured by specifying an oblique angle.

Parameters

Parameter

Description

HORIZ

Minor word which indicates that the desired dimension is the horizontal distance between two objects.

VERT

Minor word which indicates that the desired dimension is the vertical distance between two objects.

(origin)

The dimensional text location. For the methods of specification, see the Dimension Statements overivew.

ENDOF

Minor word which indicates that the extension line is to terminate at one end of the arc if the specified object is an arc. The end to be considered is further determined by a positional modifier (PMOD3).

CENTER

Minor word which indicates that the extension line is to terminate at the center of the arc if the specified object is an arc. For this option the positional modifier (PMOD3) is omitted.

TANTO

Minor word which indicates that the extension line is to terminate at one of the arc tangents if the specified object is an arc. The tangent to be considered is further determined by a positional modifier (PMOD3).

PMOD3

Determines which end of the object or position on the arc is to be dimensioned. If you are dimensioning points or arc centers, you can omit the positional modifier. For all other objects the positional modifier must be present.

obj1,obj2

The two existing objects between which the horizontal or vertical dimension is created.

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.

Dim. text

A string of up to 50 characters you may enter if the system generated value and text are not desirable. You can enter the desired dimension and/or text between single quotes ('dimension text'), or you can use a previously declared string variable.

APPEND

Minor word which indicates that the text in the next field should be appended to the dimension text.

App text

Text string which is appended to the dimension text (APPEND,'string','string'...). Each string constitutes a new line and may contain a maximum of 132 characters. The maximum number of characters which may be appended to a dimension is 600. The placement of appended text is controlled by the global parameter &APSITE.

OBLIQ

Minor word which indicates that the extension lines are to be at a specified angle to their normal orientation.

Angle

The angle, in degrees, at which the extension lines are to be rotated from their normal orientation. The rotation is about the end of the line near the object. A positive angle generates a counterclockwise rotation, and a negative angle generates a clockwise rotation.
