Revit 2025.3 API
Rebar |
A class to assist in defining rebar shapes.
A RebarShape element needs exactly one RebarShapeDefinition.

Syntax
The RebarShapeDefinition type exposes the following members.

Name | Description | |
---|---|---|
![]() | Complete | Report whether the shape definition is fully constrained. |
![]() | IsPlanar | Reports whether the shape definition lies within a plane: false if a spiral, true in all other cases. |
![]() | IsValidObject | Specifies whether the .NET object represents a valid Revit entity. |

Name | Description | |
---|---|---|
![]() | AddFormulaParameter | Add a formula-driven parameter to the shape definition. |
![]() | AddParameter | Add a parameter to the shape definition. |
![]() | CheckDefaultParameterValues | Check that the shape can be solved with the default parameter values. |
![]() | Dispose | Releases all resources used by the RebarShapeDefinition |
![]() | 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) |
![]() | GetParameterDefaultValue | Return the parameter's default value as stored in the definition. |
![]() | GetParameterFormula | Return the parameter's formula, if one is associated with it. |
![]() | GetParameters | Return the Ids of the shared parameters in the Definition. |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object) |
![]() | HasParameter | Whether the definition stores the parameter. |
![]() | RemoveParameter | Remove the parameter from the definition. |
![]() | SetParameterDefaultValue | Change the parameter's value as stored in the definition. |
![]() | SetParameterFormula | Associate a formula with the parameter. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object) |

A RebarShapeDefinition stores a set of Rebar Shape parameters. Each parameter
may be associated with:
- One or more RebarShapeConstraints; or
- A formula; or
- Neither of the above.
