Tekla Open API: Modeling Tools & Plug-Ins
Tekla Open API - Model
§ Model API– Connect to a running Tekla Structures model– Create, modify, and delete model objects
§ Read and write object attributes§ Read and write user defined attributes§ Get report properties for objects
– Interact with the user§ Get currently selected objects§ Prompt user to pick objects and locations§ Select and highlight objects for the user
– Access catalogs (material, bolt, profile, etc.)– Create and manipulate model views

Tekla Open API: Overview & Getting Started3
Tekla.Structures.Geometry3D
§ Geometric calculations and tests– Distance
§ Point to Point, Point to Line, Point to Plane– Parallel
§ Line to Line, Line to Plane, Plane to Plane§ Geometric constructions
– Intersection§ Line to Line, Line to Plane
– Projection§ Point to Line, Point to Plane, Line to Plane
§ Matrix§ Transformations from one coordinate system to another§ MatrixFactory for easy creation of matrixes

Things to Know
§ GetCurrentUser()§ OBB Class
15
Things to Know
§ Solid.IntersectAllFaces() allows use of high-accuracy solids.– Part.GetSolid(),– Solid.Intersect(LineSegment),– Solid.Intersect(Point, Point).
§ Rebar geometries fetched in deformed form by default.
16
Things to Know: Catalogs
§ Rebar catalog: Item export and import methods§ Mesh catalog: Item export and import methods§ Shape catalog: Export() method in ShapeItem class§ ImportShapes() method in CatalogHandler class§ Import from folder for:
– LibraryProfileItems,– ParametricProfileItems,– MaterialItems,– Custom components.
17
Getting profile item and user attributes
§ items = new CatalogHandler().GetLibraryProfileItems();§ aProfileItemUserParameters give list of user attributes§ aProfileItemParameters§ aProfileItemAnalysisParameters§ Type, name, Sketch & sketch info§ Export
18
Solid Class
§ Contains GetAllIntersectionPoints method that gets all theintersection points between the solid and a plane.Compared to the IntersectAllFaces method, it does notarrange the points into polygons, and is thus a lot faster.
§ Solid.SolidCreationTypeEnum.NORMAL_WITHOUT_WELDPREPS has been added to the part.GetSolid() method.

ModelHistory Class§ Works with Tekla Model Sharing§ The following methods have been added:
– GetNotSharedObjects() - returns a list of objects created or modified sincethe last Sharing WriteOut or multi-user save.
– TakeModifications() - returns the modifications since the previous call andresets the modification stamp.
– GetModifications() - returns the modifications since the previous call of– TakeModifications() without resetting the modification stamp.
§ The following methods are obsolete:– GetModifiedObjects(), GetModifiedObjectsWithType(),– GetDeletedObjects(), GetDeletedObjectsWithType(),– GetCurrentModificationStamp()

AutoFetch Property
§ New static AutoFetch property in ModelObjectEnumeratorand DrawingObjectEnumerator which increases theenumeration speed significantly.
