graphics2d.scz

2D graphics file

Export all your 2D views to the graphics2d.scz file. The structure of your graphics2d.scz file may differ for your specific CAD application, as a result, this guide does not define a strict data structure but gives guidance on how to generate it with reference to how it applies to the Revit application.

2D views and sheets

Export each 2D view as a single 2D sheet in the file. Name the 2D sheet in the following format:

<view-type>-<view-name>

Hoops node tree structure for 2D view nodes

Use the following HOOPs model tree structure:

• Models folder: Folder that contains your model files
  • Model file: Each model file comprises the following:
    • View: Store model element nodes. To construct An element node's name, concatenate the element's category name with the element's id within parentheses: Category(element-id). For example, an Elevation with a Revit ID of 12345 will have the following node name: Elevations(12345)
    • Annotations: Store annotation geometry such as text, symbols or grid lines
    • Frame: Stores the 2D view's rectangle frame

Element attributes

Each element node has the following properties:

• Name: To construct the element node's name, concatenate the element's category name with the element's id within parentheses: Category(element-id). For example, a wall with a Revit ID of 12345 will have the following node name: Walls(12345)
• PersistentID: The element’s BIMPK id, which is the integer id you give the object in "objects.id" in objects.json

  Note: If an element is only in a 2D view and not in the 3D model, for example, grids, set its value to "0".

• INV_Desc: A description of the element, which includes the element’s Category, Family, and Type data in the following format: Category>Family:Type

For a complete example, see the following Revit wall element attributes:

{  "Name": "Walls(67890)",  "PersistentID": "35",  "INV_Desc": "Walls>Wall:Interior Partition Wall"}

The following example shows a grid element's attributes:

{  "Name": "Grids(415719)",  "PersistentID": "0",  "INV_Desc": "Grids>Grid:Horizontal Grid 1"}
