Ifc Context

Create an IFC Context (or subcontext).

Input

1. Model*: the IfcOpenShell model.

2. Context Type: "Model" if you are working in 3d or "Plan" if you are working in 2d (default is "Model").

3. Context Identifier: the “Identifier” describes the purpose of the representation.

   Can be:

   • "Body": for the actual shape of the object;
   • "Box": the bounding box of the object;
   • "Axis": the parametric line determining the shape of the object;
   • "Profile": the elevation slihouette of the object;
   • "Footprint": the plan view silhouette of the object;
   • "Clearance": the clearance zone of the object;
   • "Annotation": symbolic annotations typically used in diagrams or drawings.

   (default is "Body").

4. Target View: describes the typical diagrammatic presentation that context’s geometry should be viewed in.

   Can be:

   • "MODEL_VIEW": for 3D geometry you might see in a BIM viewer;
   • "PLAN_VIEW": for 2D geometry you might see in a plan representation;
   • "ELEVATION_VIEW": for 2D geometry you might see in an elevation representation;
   • "SECTION_VIEW": for 2D geometry you might see in a section representation;
   • "GRAPH_VIEW": for 2D or 3D line or frame or path connectivity diagrams; you might use for structural frame analysis, axis-based parametric modeling;
   • "SKETCH_VIEW": for viewing abstract high-level representations such as in bubble diagrams of spatial topology;

   (default is "MODEL_VIEW").

5. Parent Id: if this is a subcontext, a parent context id should be provided.

* Required

Output

1. Model: the IfcOpenShell model.

2. Contect Id: the context (or subcontext) id.
