Revit 2025.3 API
Rebar |
A constraint that measures the length of a segment as measured by projecting onto a direction
that is not parallel to the segment.

The RebarShapeConstraintProjectedSegmentLength type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | RebarShapeConstraintProjectedSegmentLength | Constructs a new instance of a RebarConstraintProjectEdgedLength object using a shape parameter, direction, and reference types. |
Properties| Name | Description | |
|---|---|---|
 | Direction | A vector specifying the direction of the constraint. The direction is fixed, and the shape is always constructed so that the segment direction has a positive dot product with this vector. |
| IsValidObject |
Specifies whether the .NET object represents a valid Revit entity.
(Inherited from RebarShapeConstraint) |
| TripleProductSign | Sign of the z-coordinate of the cross product of the Direction property with the segment vector. TripleProductSign is 1 if the segment direction is to be on the left of the constraint direction, or -1 if the segment direction is to be on the right. |
Methods| Name | Description | |
|---|---|---|
| Dispose | (Inherited from RebarShapeConstraint) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetParamId |
Return the Id of the parameter associated with this constraint.
(Inherited from RebarShapeConstraint) |
| GetSegmentEndReferenceType | Choice of two possibilities for the start and end references of the length constraint. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
Remarks
The constraint has two references, indexed by 0 and 1, that do not have to
correspond to the start and end of the segment. The constraint also specifies
a direction as a 2D vector, which is not necessarily parallel to the segment,
but must point from the segment's start toward its end.
