====== Create New Symbols Dataset ======

Creating a New Dynamic Symbols Dataset makes it possible to create a new vector dataset with dynamic symbols and add it to the current Workspace.

===== Concepts =====

Dynamic Symbols provide symbol choice, size and orientation to be set for each individual object. Dynamic Symbols are created using Point objects and a Legend reading symbol parameters from attribute values. \\
Dataset and Legend must be kept together.

By defining a symbol dataset, a graphic representation of each object is stored as an attribute.

Basically, point objects are dynamically drawn not only by a legend but also by their proper attribute values. To do so, the legend uses the classification 'direct link' which can be technically applied on each graphic parameter. See [[214:desktop:dataset:legend:classification:direct|]].

===== Attributes =====

The configuration of a Dynamic Symbol Library is preset and results in a point vector file with 3 attributes: Name, Orientation (DEG), and Size (Point on Screen). By default, the legend uses the indication 'direct link' on those 3 attributes. Use the [[214:desktop:dataset:legend:index|Legend Editor]] for additional changes and the [[214:desktop:dataset:contents:index|Structure panel]] to modify or add attributes.

===== Save =====

The legend will be saved in [[214:technology:supported_formats:other:olg|the Orbit legend file]] (.olg) as a [[214:desktop:dataset:legend:classification:direct|direct link]] legend.

===== Create Objects in a Symbol dataset =====

To create new symbols (point objects) on the map :
  - flag the record indicator {{orbit_desktop:tools:editing:record_indicator.gif?nolink}} in the dataset list of the required dataset
  - go to the [[214:desktop:tools:edit|]]
  - and use the New Symbol function to create new objects on the map. \\ {{orbit_desktop:tools:editing:sidebar_newobject.png?nolink}} \\ More information on [[214:desktop:tools:edit#Place Symbol Window]]
