Members

head

General element header.

linePen

(Overridden) pen attribute index.

ltypeInd

Line type attribute index.

roomSeparator

Is this arc a zone boundary?

determination

Line category:

`APILine_DetOrigin`	Default line category. Lines in the Drafting line category are not affected by the Line Weight and Section Fill settings chosen in Display Options.
`APILine_DetInnerLine`	A skin separator line separates skins of composite structures. Lines in the Skin Separator category will be either hidden or shown depending on the Cut Fill type chosen in Display Options. Also, lines in the Skin Separator category can be optionally placed onto their own layer during DXF/DWG conversion functions.
`APILine_DetContourLine`	Lines in the Cut line category will be affected if you have chosen the ‘Bold Cut Line’ setting in the Line Weight menu of Display Options.

arrowData

Arrow data for the arc ends.

penWeight

Pen weight for the arc (can override the weight in linePen, otherwise set it to API_DefPenWeigth: use default weight of the pen).

origC

Coordinate of the center point.

r

Radius.

angle

0.0, or the angle of the ‘a’ axis.

ratio

1.0, or ‘a/b’ of the ellipse.

begAng

Beginning angle of the arc.

endAng

End angle of the arc.

reflected

Is the ellipse reflected onto the smaller axis?

whole

Is this a whole arc? (output only)
