It hurts my a soul a bit that this a right-click menu feature only. Has anyone figured out a shortcut to remote control? Maybe by using a custom component name?

I went down a small rabbit hole on recreating Custom Preview in code, and adding a filter input. There is A LOT of documentation on Custom Preview coding on the forums but so far as I can see, nothing is as reliable as the original in terms of toggling preview and enable. Previews get stuck on your screen even when you delete the components. By trying to solve one problem I have to add another larger problem.

Ultimately there is another level of convolution I’d love to add which is Layout Filters. Preview to specific layout pages only, or specific details. That mountain seems pretty high though, I’d maybe settle for controlling Viewport Filters on a score Custom Previews at a time.

Has anyone tackled any of this for have any advice?

Much appreciated.

 private void RunScript(string nickname, string filter, ref object A)
  {
    var objs = this.Component.OnPingDocument().Objects;
    foreach (var obj in objs)
    {
      if (obj.GetType().ToString() == "Grasshopper.Kernel.Components.GH_CustomPreviewComponent")
      {
        var prev = (Grasshopper.Kernel.Components.GH_CustomPreviewComponent) obj;

        if (prev.NickName == nickname)
          prev.ViewportFilter = filter;
      }
    }
  }
