Methods

ClosestPoint(IfcVector3, bool)

Computes the point on this grid axis closest to the specified 3D point.

public IfcVector3 ClosestPoint(IfcVector3 point, bool segmentOnly = false)

Parameters

point IfcVector3
segmentOnly bool

Returns

IfcVector3

DistanceToPoint(IfcVector3, bool)

Computes 3D Euclidean distance from the specified point to this grid axis.

public double DistanceToPoint(IfcVector3 point, bool segmentOnly = false)

Parameters

point IfcVector3
segmentOnly bool

Returns

double

DistanceToPoint2D(IfcVector3, bool)

Computes horizontal 2D distance (XY plane) from the specified point to this grid axis.

public double DistanceToPoint2D(IfcVector3 point, bool segmentOnly = false)

Parameters

point IfcVector3
segmentOnly bool
