I currently have a custom tool that, on mouse click, draws a LineTool and multiple TextTools. Is there any way to "group" the Tools together so that when I "Erase Drawing" they delete as one, rather than having to delete each separately?

Keep track of all the IDs for the user drawings you create as a "group". On each loop in your code, at the end of the loop, run through your groups, and if any items is a group is no longer present, delete the others. See: GetUserDrawnDrawingByLineNumber UserDrawnChartDrawingExists DeleteUserDrawnACSDrawing Will prob need to use some persistent storage to a <list> (list of lists?) to manage your groups. |

Thank you for your response. I'm still trying to visualize this. Given that each of my custom drawings has 8 Tools/LineNumbers. As I place them on the chart and then go back to an earlier drawing, I don't see how "Erase Drawing" will know which set of LineNumbers to delete. Also, is "Erase Drawing" even exposed to ASCIL? I'll have to research/think on this some more.

You created the drawings, you know the IDs, you can store them (perhaps in a list). You need to scan your list, and for every drawing/Tool/LineNumber, call UserDrawnChartDrawingExists and see if one/some/all are missing? If one is missing, remove the others. For all removed (by your code, or the user) drawings...remove them from your tracking list.

Right, so what about the built-in "Erase Drawing"? It seems like I'll have to create my own "delete drawing" that I can customize to loop the list/Map
