Object 22 "Dimension Line Elliptical" (Entity Type "Object") Changed in Version 2021.0

www.CAD6.com

 

The two angles determine the arrow's end-points, but not necessarily the line's end-points. If the arrows are rotated, the dimension line will overlap the given angles.

 

A dimension line is by definition an "open" object, i.e. it has a non-closed outline and cannot be filled. Nevertheless, the dimension arrows will be filled if required. This is independent from the object's properties!

Data Block 006( Vector2 )

Data Block 005( Angle1 )

Data Block 005( Angle2 )

Data Block 101( Orientation )

Data Block 220( Options )

 

Parameters

Center

[MKI_POINT] Center point of the ellipse.

Vector1

[MKI_POINT] First vector of the ellipse.

Vector2

[MKI_POINT] Second vector of the ellipse.

Angle1

[MKI_POINT] Start angle of the ellipse arc.

Angle2

[MKI_POINT] End angle of the ellipse arc.

Orientation

[double] Direction of the arc. If Orientation >= 0, the arc is drawn counter-clockwise from the start angle to the end angle. If Orientation < 0, the arc is drawn clockwise.

Options

[MKI_DIMLINE] Dimension line parameters.

 

Attributes New in Version 2021.0

A dimension line 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.
