新しく開発された API を解析モデリングのコンテキストで説明します。
新しい API クラス
AnalyticalElement -すべての解析オブジェクトの基本クラスを表します。AnaltyicalModel の代替です。
Transform GetTransform () - Returns the transform which reflects Analytical Element orientation.
AnalyzeAs AnalyzeAs - This represents the Analyze As parameter assigned to Analytical Element.
Reference GetReference (AnalyticalModelSelector selector) - Returns a reference to a given curve within the Analytical Element.
ElementId MaterialId - Defines the Material Id for the Analytical Element.
AnalyticalMember - 構造解析モデルの直線要素を表します。AnalyticalModelStick と AnalyticalModelColumn の代替です。
AnalyticalMember Create(Document aDoc,Curve curve) - Method which creates a new instance of an Analytical Member within the project.
AnalyticalStructuralRole StructuralRole - The structural role assigned to the Analytical Member.
Curve GetCurve () - Returns the curve of the Analytical Member.
void SetCurve(Curve curve) - Sets the curve for the Analytical Member. This method disconnects elements from other analytical elements (if the end nodes are in the same position).

If the user wants to move the corner, and keep the connection, there are other ways for achieving that such as ElementTransformUtils.moveElements.
bool IsValidCurve(Curve curve) - Verifies if the curve is valid for an Analytical Member.
void FlipCurve() - Flips the ends of the Analytical Member.
StructuralSectionShape StructuralSectionShape - The structural section shape of the Analytical Member (read only).
ElementId SectionType - The id of the type from the structural family assigned to the Analytical Member.
double CrossSectionRotation - Cross-section rotation of the Analytical Member.
AnalyticalPanel Create(Document aDoc, CurveLoop curveLoop) - Method which creates a new instance of an Analytical Panel within the project.
CurveLoop GetOuterContour() - Returns the Curve Loop that defines the geometry of the Analytical Surface element.
bool IsCurveLoopValid(CurveLoop profile) - Checks if curve loop is valid for Analytical Panel.
void StartWithNewSketch(ElementId elementId) - Starts a sketch edit mode for an element which, at this moment, doesn't have a sketch.
void SetOuterContour(CurveLoop outerContour) - Sets the Curve Loop that defines the geometry of the Analytical Surface element.

AnalyticalMember の場合と同様に、解析用パネルの等高線を設定すると、他の解析要素との接続が切断されます。コーナーの移動時に接続を維持する場合は、ElementTransformUtils.moveElements などの他の方法を使用します。
ISet<ElementId> GetAnalyticalOpeningsIds() - Returns the Analytical Openings Ids of the Analytical Panel.
ElementId SketchId - Sketch associated to this Revit element.
AnalyticalStructuralRole StructuralRole - Structural role assigned to the Analytical Panel.
AnalyticalOpening Create(Document doc, CurveLoop curveLoop, ElementId panelId) - Method which creates a new instance of an Analytical Opening within the project.
CurveLoop GetOuterContour () - Returns the Curve Loop that defines the geometry of the Analytical Surface element.
bool IsCurveLoopValidForAnalyticalOpening(CurveLoop loop, Document aDoc, ElementId panelId) - Checks if curve loop is valid for Analytical Opening.
void SetOuterContour(CurveLoop outerContour) - Sets the Curve Loop that defines the geometry of the Analytical Surface element.
ElementId PanelId - ElementId of the host Analytical Panel.
ElementId SketchId - Sketch associated to this Revit element.
AnalyticalToPhysicalAssociationManager - 解析要素と物理要素の関連付けを管理します。以前は、要素自体が互いを認識しており、ユーザーは要素をコントロールすることができませんでした(関連付けを変更できませんでした)。この新しい方法を使用すると、関連付けを編集できます。1 対 1 の関連付けがサポートされており、要素を同時に複数の関連付けの一部にすることはできません。
AnalyticalToPhysicalAssociationManager GetAnalyticalToPhysicalAssociationManager(Document doc) Returns the AnalyticalToPhysicalAssociationManager for this document.
void AddAssociation(ElementId analyticalElementId, ElementId physicalElementId) - Adds a new association between an analytical element and a physical element.
void RemoveAssociation(ElementId elementId) - This method will remove the association for the element with the given ElementId.
ElementId GetAssociatedElementId (ElementId elementId) - Returns id of the element which is associated with the given ElementId.
bool HasAssociation(ElementId id) - Verifies if the element has already defined an association.
AnalyticalNodeData GetAnalyticalNodeData ( Element element) - Returns AnalyticalNodeData associated with this element, if it exists.
AnalyticalNodeConnectionStatus GetConnectionStatus () - Returns the Connections Status for an Analytical Node.
AnalyticalLinks、BoundaryConditions、Loads が移行され、新しい要素で動作するようになりました。これらに関連する API は、ほとんどの場合は同じままです。荷重に対する機能が強化されました。

{
transaction.Start();
//create curve which will be assigned to the analytical member
Line line = Line.CreateBound(new XYZ(0, 0, 0), new XYZ(5, 0, 0));
//create the AnalyticalMember
AnalyticalMember analyticalMember = AnalyticalMember.Create(document, line);
analyticalMember.StructuralRole = AnalyticalStructuralRole.StructuralRoleBeam;
transaction.Commit();
}
解析用パネルの作成

using (Transaction trans = new Transaction(doc, "AddAssociationBetweenPhysicalAndAnalyticalElements"))
{
trans.Start();
ElementId analyticalElementId = ContextualAnalyticalModel.Utilities.GetSelectedObject(activeDoc, "Please select analytical element");
ElementId physicalElementId = ContextualAnalyticalModel.Utilities.GetSelectedObject(activeDoc, "Please select physical element");
//gets the AnalyticalToPhysicalAssociationManager for the current document
AnalyticalToPhysicalAssociationManager analyticalToPhysicalManager = AnalyticalToPhysicalAssociationManager.GetAnalyticalToPhysicalAssociationManager(doc);
if (analyticalToPhysicalManager == null)
return Result.Failed;
//creates a new association between physical and analytical elements
analyticalToPhysicalManager.AddAssociation(analyticalElementId, physicalElementId);
trans.Commit();

SketchEditScope フレームワークを使用して解析用パネルの境界を編集する

// Start a sketch edit scope
SketchEditScope sketchEditScope = new SketchEditScope(document, "Replace line with an arc");
sketchEditScope.StartWithNewSketch(analyticalPanel.Id);
using (Transaction transaction = new Transaction(document, "Modify sketch"))
{
transaction.Start();
//replace a boundary line with an arc
Line line = null;
Sketch sketch = document.GetElement(analyticalPanel.SketchId) as Sketch;
if (sketch != null)
{
//find first line in the sketch profile
…..
}
// Create arc
XYZ normal = line.Direction.CrossProduct(XYZ.BasisZ).Normalize().Negate();
XYZ middle = line.GetEndPoint(0).Add(line.Direction.Multiply(line.Length / 2));
Curve arc = Arc.Create(line.GetEndPoint(0), line.GetEndPoint(1), middle.Add(normal.Multiply(20)));
// Remove element referenced by the found line.
document.Delete(line.Reference.ElementId);
// Model curve creation automatically puts the curve into the sketch, if sketch edit scope is running.
document.Create.NewModelCurve(arc, sketch.SketchPlane);
transaction.Commit();
}
sketchEditScope.Commit(new FailurePreproccessor());
解析用ノードを移動して接続を維持する

// Create the connected Analytical Member

// Select the node
Reference eRef = activeDoc.Selection.PickObject(ObjectType.PointOnElement , "Select an Analytical Node");
// Move the Analytical Node using ElementTransformUtils
using (Transaction transaction = new Transaction(document, "Move node with ElementTransformUtils"))
{

ElementTransformUtils.MoveElement(document, eRef.ElementId, new XYZ(-5, -5, 0));
transaction.Commit();
}
解析用サーフェスの等高線の点を取得する
private List<XYZ> GetSurfaceContourPoints( Document doc, ElementId elementId )

List<XYZ> contourPoints = new List<XYZ>();
AnalyticalModel analyticalModel = (doc.GetElement(elementId) as AnalyticalModel);
IList<Curve> curves = analyticalModel.GetCurves(AnalyticalCurveType.RawCurves);
// Iterate over curves and make the desired processing
…...
return contourPoints;
}
private List<XYZ> GetSurfaceContourPoints( Document doc, ElementId elementId )
{
// Create point list, get list of curves from analytical model
List<XYZ> contourPoints = new List<XYZ>();

ライン境界条件を作成する
以前の解決策の場合:
private BoundaryConditions CreateLineBC(Element hostElement)
{
Document createDoc = hostElement.Document.Create;
// use Document.NewLineBoundaryConditions Method
BoundaryConditions createdBC =
createDoc.NewLineBoundaryConditions(hostElement.GetAnalyticalModel(), 0, 0, 0, 0, 0, 0, 0, 0);
return createdBC;
}
新しい解決策の場合:
private BoundaryConditions CreateLineBC(Element hostElement)
{
Document createDoc = hostElement.Document.Create;
// use Document.NewLineBoundaryConditions Method
AnalyticalElement analyticalElement = GetAnalyticalElement(hostElement);
BoundaryConditions createdBC =
createDoc.NewLineBoundaryConditions(analyticalElement, 0, 0, 0, 0, 0, 0, 0, 0);
return createdBC;
}
