Determines whether 2 vectors are the same within the given tolerance.
Namespace:
Autodesk.Revit.DB
Assembly:
RevitAPI
(in RevitAPI.dll) Version: 21.0.0.0 (21.1.1.109)
Syntax
C# 


Visual Basic 


Visual C++ 


Parameters
 source

Type:
Autodesk.Revit.DB
XYZ
The vector to compare with this vector.
 tolerance

Type:
System
Double
The tolerance for equality check.
Return Value
True if the vectors are the same; otherwise, false.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)
.
Exceptions
Exception  Condition 

Autodesk.Revit.Exceptions ArgumentNullException  Thrown when source is a null reference ( Nothing in Visual Basic) . 
Autodesk.Revit.Exceptions ArgumentException  Thrown when tolerance is less than 0.
