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 toAPI_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)
Requirements
- Version: API 4.1 or later
- Header: APIdefs_Elements.h
