Tessellated |
A class that permits structured building of geometry or
a mesh from a collection of connected faces.
Contains all closed face sets and custom precisions.

SyntaxThe TessellatedShapeBuilder type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | TessellatedShapeBuilder | Constructs a new instance of a TessellatedShapeBuilder. |
Properties| Name | Description | |
|---|---|---|
 | Fallback | Defines acceptable fallback if the desired type of geometry can't be built. |
| GraphicsStyleId | Optional - if set, the built geometry will use that graphics style. |
| IsFaceSetOpen | Flag whether the current set of connected faces is open and additional tessellation faces can be added to it. |
| IsValidObject |
Specifies whether the .NET object represents a valid Revit entity.
(Inherited from ShapeBuilder) |
| LogInteger | Integer value used for logging, if it is performed. Usually the number of the face set(s) in the IFC file, from which they are imported. Any value is acceptable. |
| LogString | String used for logging, if any. Usually the name of the file from which face sets were imported. |
| NumberOfCompletedFaceSets | Number of completed face sets. |
| OwnerInfo | String used for logging, if any. Usually describes the element or object, which either defined or will own the geoemtrical objects to be built. |
| Target | Requests the type of geometry to be built. |
Methods| Name | Description | |
|---|---|---|
| AddFace | Adds a face to the currently open connected face set. |
| AreTargetAndFallbackCompatible | Checks whether this combination of fallback and target parameters can be used as a valid combination of inputs. |
| Build | Builds the designated geometrical objects from the stored face sets. Stores the result in this TessellatedShapeBuilder object. |
| CancelConnectedFaceSet | Cancels the current face set - i.e., all data from it will be lost and the builder will have no open connected face set anymore. |
| Clear | Erases all face set and clears the logs, if any. |
| CloseConnectedFaceSet | Closes the currently open connected face set. |
 | CreateMeshByExtrusion | |
| Dispose | (Inherited from ShapeBuilder) |
| DoesFaceHaveEnoughLoopsAndVertices | Checks whether 'face' has enough loops and vertcies to be valid. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| GetBuildResult | Get the built geometry, build status and other data stored in TessellatedShapeBuilderResult. Clears the stored data. |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| OpenConnectedFaceSet | Opens a new connected face set. |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
Remarks
Creates a geometry populated with faces defined by TessellatedFace objects
stored in the input connected face sets.
The faces defined by each connected face set may form an open shell or
the boundary of a solid 3D region.
All faces are planar and have polyline boundaries, defined
as sequences of 3d coordinates.
Faces are added to the builder as a part of connected face sets,
representing faces which share edges.
Order of faces in the sets is irrelevant. Faces can only
be added to the builder when a face set has been opened and is available
to take in faces (use OpenConnectedFaceSet(Boolean) to open a new face set).
Before attempting to build Revit geometry from the builder
the current face set should be closed
(CloseConnectedFaceSet).
The builder allows for the possibility of multiple face sets.
The builder will try to create a geometry valid in Revit despite
inconsistencies or omissions in the input data.
- For each connected face set, it will check the face orientations and change them wherever needed so that the orientations of the faces in that set are consistent.
- If a connected face set is closed, it will check if the face normals point outward. If not, it will reverse the orientations of all faces. That means, each closed connected face set will represent a solid.
- It does not support the definition of a "void", even if the user had set the orientations of the faces to define a "void".
- If there is more than one connected face set, it does not check if they intersect or overlap each other.
