How to get more accurate selection with default viewport select tool

[MichaelBelousov]

I have a user reporting that the viewport select tool is unreliable especially when there are many small elements. They are trying to select a feature comprised of many many elements. I can't show their data but above I show something similar by zooming out a bit.

I can see some of it is overlap based, and on their data it seemed correlated to the level of detail of tiles loaded.

Is there an existing way to run viewport select frustrums without viewport visibility and instead on the precise geometry?

The default selection logic chooses visible elements by reading pixels from the screen.

You can try enabling ToolSettings.enableVolumeSelection and see if it works for your data.

  /** If true, drag box selection will accept spatial elements that are inside or overlap a clip volume instead of only what is visible in the view.
   * @note Enabling is not recommended for web applications.
   * @beta
   */
  public static enableVolumeSelection = false;

There is currently an open issue with enableVolumeSelection not working correctly for a particular test case.

• If the "feature" was created as an assembly, using assembly scope would select the feature w/o needing the user to identify a volume that fully encloses it, might contain other elements you don't want to select, etc.

Thank you Brien I'll try that out later today!
