Synopsis

obj = LDIM/PERP,(origin),baseline,[{ENDOF|CENTER|TANTO},]"PMOD3",obj[,VIEW,'View Name'][,Dim. text][,APPEND,App. text]

Description

Creates a perpendicular dimension between a baseline and a previously defined object. The baseline must be a previously defined line. The extension lines are parallel to the baseline.

Parameters

Parameter

Description

PERP

Minor word which indicates that the dimension is to be the perpendicular distance from the baseline to an object.

(origin)

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

baseline

An existing line from which the perpendicular dimension is measured.

ENDOF

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

CENTER

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

PMOD3

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

obj

An existing object to which the perpendicular dimension is measured.

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.
