Detailed Description

Represents a cubic or Bezier-spline.

Remarks: The coordinates of the spline points are given in the coords field of API_ElementMemo. The last and the first coordinate in coords should be different; and the coordinate with index 0 is also used. If autoSmooth is false, then the handle positions for every spline point are given in the bezierDirs field in API_ElementMemo.

Line category:

Category	Meaning
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.
