TransformElementsTool Class

Edit tool base class for applying a transform to element placements. Example of a tool that would translate elements:

class SampleMoveElementsTool extends TransformElementsTool {
  public static override toolId = "SampleMoveElements";
  public static override iconSpec = "icon-move";
  protected calculateTransform(ev: BeButtonEvent): Transform | undefined {
    return (this.anchorPoint ? Transform.createTranslation(ev.point.minus(this.anchorPoint)) : undefined);
  }
  public async onRestartTool(): Promise<void> {
    const tool = new SampleMoveElementsTool();
    if (!await tool.run()) return this.exitTool();
  }
}
