|
This document is archived and information here might be outdated. Recommended version. |
Constructs an arc from a center point, a starting point, and an arc length.
[Visual Basic .NET] Public Sub ConstructArcDistance ( _ ByVal Center As IPoint, _ ByVal from As IPoint, _ ByVal isCCW As Boolean, _ ByVal arcDistance As Double _ )
[C#] public void ConstructArcDistance ( IPoint Center, IPoint from, bool isCCW, double arcDistance );
[C++]
HRESULT ConstructArcDistance(
IPoint* Center,
IPoint* from,
VARIANT_BOOL isCCW,
double arcDistance
);
[C++] Parameters Center
Center is a parameter of type IPoint* from
from is a parameter of type IPoint* isCCW
isCCW is a parameter of type bool arcDistance
arcDistance is a parameter of type double
Constructs a CircularArc given the Center Point, From Point, the desired orientation, and the desired CircularArc Length. The Arc Distance must be less than 2 * Pi * the Radius (the distance between the From Point and the Center Point), otherwise an error is returned.
-isCCW stands for "is counter clockwise"
