Arcs
autocad_entity: autocad_arc
This geometry type is stored in an AutoCAD arc entity. Arc features are like ellipse features, except two additional angles control the portion of the ellipse boundary which is drawn. There are several properties of an FME arc geometry that may result in it being written as an AutoCAD entity other than an arc.
If this arc geometry is circular and has a sweep angle of 360 degrees, it will be stored in an AutoCAD circle entity instead of an arc entity. If this arc geometry is not circular, it will be stored in an AutoCAD ellipse entity.

autocad_primary_axis |
The length of the semi-major axis in ground units. Currently the value of the primary axis is always equal to the value of the secondary axis as AutoCAD arcs must be circular. When writing to an AutoCAD file, only the primary axis value is used. Range: 64-bit floating point number > 0 Default: No default |
autocad_secondary_axis |
The length of the semi-minor axis in ground units. Currently the value of the primary axis is always equal to the value of the secondary axis as AutoCAD arcs must be circular. When writing to an AutoCAD file, only the primary axis value is used. Range: 64-bit floating point number > 0 Default: No default |
autocad_start_angle |
How FME calculates start_angle and sweep_angle Range: 0.0..360.0 Default: 0 |
autocad_sweep_angle |
How FME calculates start_angle and sweep_angle Range: 0.0..360.0 Default: No default |
autocad_rotation |
The rotation of the arc. The rotation angle specifies the angle in degrees from the horizontal axis to the primary axis in a counterclockwise direction. However, this value is fixed at 0 as AutoCAD does not support rotation of circular arcs. Range: 0 Default: 0 |
