Data Block Sequence

- Center-point

- Radius definition

The point (cx,cy) determines the circle's center-point, the point (rx,ry) is a point on the circle's outline and thus defines the radius.

Construction Aid objects will usually not be output to printer or clipboard. Although a Construction Aid circle is by definition a "closed" object, it will never be filled.

Attributes New in Version 2021.0

A Construction Aid circle may contain attribute data blocks (see MKI_BLOCK_ATTRIBUTE) of types "local", "outline", and "point". Their position in the list of data blocks must be as follows:

-	Outline attributes must be placed anywhere behind the first point. Any outline attribute after the first point data block belongs to the outline.

-	Point attributes must be placed behind the respective point. Any point attribute after point data block P and before the next point data block (or end of object) belongs to that point P.

-	Local attributes should be placed behind all other datablocks and attributes.

The total number of attributes of each type (local, outline, point) per respective element (entity, outline, and point) is limited to MKI_ATTRIBS_PER_OBJECT.
