IsAlmostEqualTo Method (XYZ, Double)

XYZ Is Almost Equal To(XYZ, Double) Method

Determines whether 2 vectors are the same within the given tolerance.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public bool IsAlmostEqualTo(
	XYZ source,
	double tolerance
)

Parameters

source XYZ
The vector to compare with this vector.
tolerance Double
The tolerance for equality check.

Return Value

Boolean
True if the vectors are the same; otherwise, false.
Exceptions
Exception Condition
ArgumentNullException Thrown when source is .
ArgumentException Thrown when tolerance is less than 0.
Remarks
This routine uses an input tolerance to compare two vectors to see if they are almost equivalent. Because it is comparing two vectors the tolerance value is not in length units but instead represents the variation in direction between the vectors. For very small tolerance values it should also be possible to compare two points with this method. To compute the distance between two points for a comparison with a larger allowable difference, use DistanceTo(XYZ) .
