Synopsis

obj = CCDIM/(origin),arc1,[VIEW,'View Name',]arc2[,VIEW,'View Name'][,{LEFT|RIGHT},][,Dim. text][,APPEND,App. text]

Description

Creates a dimension which represents the difference between the circumferences of two concentric circles.

NOTE: The circles are assumed to be concentric based on the center of the first circle. A dimension is created even if the circles are not concentric. The radius values of the circles are subtracted to arrive at a number for the dimension. Therefore, if you dimension circles which are not exactly concentric, the dimension may still be acceptable. However, if the circles are not very close to being concentric, the dimension display (where the arrows point) may be unacceptable.

Parameters

Parameter

Description

(origin)

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

arc1,arc2

The two existing arcs to be dimensioned.

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.

LEFT and RIGHT

Determines which side of the text the leader line begins on, as viewed in a readable position. You can also control this parameter by using global parameters &LEFT and &RIGHT. Enter the following statement:

&LEADER=&RIGHT or &LEADER=&LEFT

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.
