Constructor & Destructor Documentation
◆ OdGeCircArc2d() [1/6]
| OdGeCircArc2d::OdGeCircArc2d | ( | ) |
- Parameters
-
center [in] Center of arc. radius [in] Radius of arc. startAng [in] Starting angle of arc. endAng [in] Ending angle of arc. refVec [in] The reference vector defining arc angle 0. startPoint [in] Startpoint of arc. secondPoint [in] Second point on a 3-point arc. endPoint [in] Endpoint of arc. bulge [in] Specifies the bulge of the arc. bulgeFlag [in] Specifies how bulge is to be interpreted. source [in] Object to be cloned.
- Remarks
- The default constructor creates a circle with a center of (0,0) and a radius of 1.
To construct a circle, set endAng = startAng + Oda2PI
If bulgeFlag == true, then bulge is the maximum distance from the arc perpendicular to a chord between the start and endpoints.
If bulgeFlag == false, the bulge is the tangent of 1/4 the included angle of the arc, measured counterclockwise.
- Remarks
- All angles are expressed in radians.
startAng must be less than endAng.
