构造函数
McGeCircArc2d(const McGePoint2d& startPoint, const McGePoint2d& endPoint, double bulge, Mdesk::Boolean bulgeFlag = Mdesk::kTrue);
|
参数 |
说明 |
|
const McGePoint2d& startPoint |
输入弧线的起始点 |
|
const McGePoint2d& endPoint |
输入弧线的终止点 |
|
double bulge |
圆弧的凸度 |
|
Mdesk::Boolean bulgeFlag = Mdesk::kTrue |
如果Mdesk::kTrue,则说明bulge是弧线和两输入点连线间最大的距离。如果bulgeFlag是Mdesk::kFalse,则说明“bulge”是含有角度(tan(ang/4))1/4的正切值,“ang”是输入两点间弧段的角度 |
