ExecuteBooleanOperation Method

Boolean Operations Utils Execute Boolean Operation Method

Perform a boolean geometric operation between two solids, and return a new solid to represent the result.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public static Solid ExecuteBooleanOperation(
	Solid solid0,
	Solid solid1,
	BooleanOperationsType booleanType
)

Parameters

solid0 Solid
The first solid object. A copy will be taken of the input object, so any solid whether obtained from a Revit element or not would be accepted.
solid1 Solid
The second solid object. A copy will be taken of the input object, so any solid whether obtained from a Revit element or not would be accepted.
booleanType BooleanOperationsType
boolean operation type.

Return Value

Solid
The result geometry.
Exceptions
Exception Condition
ArgumentNullException A non-optional argument was null
ArgumentOutOfRangeException A value passed for an enumeration argument is not a member of that enumeration
InvalidOperationException Failed to perform the Boolean operation for the two solids. This may be due to geometric inaccuracies in the solids, such as slightly misaligned faces or edges. If so, eliminating the inaccuracies by making sure the solids are accurately aligned may solve the problem. This also may be due to one or both solids having complexities such as more than two faces geometrically meeting along a single edge, or two coincident edges, etc. Eliminating such conditions, or performing a sequence of Boolean operations in an order that avoids such conditions, may solve the problem.
Example 
private void ComputeIntersectionVolume(Solid solidA, Solid solidB)
{
    Solid intersection = BooleanOperationsUtils.ExecuteBooleanOperation(solidA, solidB, BooleanOperationsType.Intersect);
    double volumeOfIntersection = intersection.Volume;
}
