Step 12 of 17: Understand the Data Tree Structure

A3.12: Data Tree, Project References & Elevator Project Value Nodes

Written by Alexandra Göttert

This begins the Data Tree & Project References section: how the Data tree represents a project, how project references are built, and where the most commonly referenced project values live.

Prerequisites

  • You can add view frame and component annotations.

Steps

Date tree structure

1.) Understand what the Data tree represents. Project-specific values and objects are created via the DigiPara Liftdesigner Data tree, which represents the project as a text structure — for example, the landing door of Entry1 (the 2nd floor).

Understand what gets a node.

  • Every component/object and every dimension has its own node.

  • List objects — such as entrances/landing doors, or rail brackets — each get an individual node.

2.) Understand how major objects and list indexing work. Major objects (e.g. one elevator/shaft, 5 floors, 3 loaded sheets) are represented at the top; list objects always start with index 0.

3.) Understand project references. Project references are built from the names of the selected object and its parents — for example, the car frame object's reference is "Shaft0.Car.Frame.". Object-related references typically end with a dot.

Elevator project value nodes

4.) Know the L_Projects. and L_StandardTab. nodes. Typically referenced project values are located under these nodes.

5.) Know the Shaft. and FLL. nodes. Also commonly referenced — the Shaft. node and the FLL. node.

6.) Edit project specification values via Main Project Data. Values under the L_Projects. node (used mainly in title blocks) can be edited via the Main Project Data… dialog.

Result

You understand how the Data tree represents a project as text, how objects and list items get their nodes, and how project references are built from an object's name and its parents — and you know where to find the most commonly referenced project value nodes and how to edit the ones used in title blocks.
