CIRCLE (CIRC)

Attributes

Basic Creation Method

NEW CIRCLE DEF X value Y value X value Y value

(‘manual’ method of NEW CIRCLE DEF @ command described. See Create Primitives . . . for further information. The method applies to all primitives described, except where otherwise specified.)

Note:
If used with an existing Circle the DEF command always sets ADEG=0 and ORIG=center

Identification

ID CIRC @

The method applies to all primitives described, for example ID ELLI @ (ellipse), ID RECT @ (rectangle).

DIAMETER value [DESIGN]

RADIUS  value [DESIGN]

If Design specified and if underneath a VIEW from which a scale can be obtained, a scaled circle is drawn and the diameter stored in the database as a Design value.

DIAM @

Sets DIAM equal to the distance between the two points, ADEG equal to the angle to this line from X axis; if ORIG is CIRCUMFERENCE, origin is positioned at the first hit.

DIAM X value Y value X value Y value

Manual method.

Redefine the Origin

ORIGIN @

Prompts:

Select a possible origin of the CIRC

ORIG center

Sets ORIG as required and changes position of origin to point specified. The Circle itself does not move.

ORIG CIRCUMFERENCE

Position (absolute)

ORIG X value Y value

ORIG center @

ORIG CIRCUMFERENCE @

ORIG IDP @

ORIG POS @

ORIG ID @

ORIG IDDP @

The last option (ORIG IDDP @) places the primitive on the drafting point used by another primitive and hence makes sure connectivity for the DRAG command.

Move about the origin

OCOD CIRCUMFERENCE

Moves origin to circumference of Circle.

Rotate about the origin

ADEGREE value

Sets ADEG as specified, causing the circle to rotate about its origin. (If this is at the center then no visible change is seen.)

Query

In addition to the standard attribute queries:

Q DESC

Queries the origin, position and diameter

Q DIAM

Queries the diameter in Annotation or Design coordinates as appropriate

Q ORIG

Queries the origin and its position

Q OFFS

Queries the position relative to the NOTE origin
