ElementSetTool Class
The ElementSetTool class is a specialization of PrimitiveTool designed to unify operations on sets of elements. Use to query or modify existing elements as well as to create new elements from existing elements. Basic tool sequence:
- Populate ElementSetTool.agenda with the element ids to query or modify.
- Gather any additional input and if requested, enable dynamics to preview result.
- Call processAgenda to apply operation to ElementSetTool.agenda.
- Call onProcessComplete to restart or exit. Common element sources:
- Pre-selected elements from an active SelectionSet.
- Clicking in a view to identify elements using ElementLocateManager.
- Drag box and crossing line selection. Default behavior:
- Identify a single element with left-click.
- Immediately apply operation.
- Restart. Sub-classes are required to opt-in to additional element sources, dynamics, AccuSnap, additional input, etc.
