Ask for Sketch from user

Question

After drawing a polygon on my map. i am required to get a direction Polyline from the user. In ArcObjects, I was able to accomplish this like the following. This would give me a line that a user drew that represented a "direction" IActiveView activeView = pDocument.ActiveView; IScreenDisplay screenDisplay = activeView.ScreenDisplay; string cursorLocation = ProMapSettings.AssemblyDirectory + @ProMapSettings.CursorFileLocation + "RowDirection.cur"; bool cursorLocationExists = File.Exists(cursorLocation); if (cursorLocationExists) { System.Windows.Forms.Cursor newCursor = new System.Windows.Forms.Cursor(cursorLocation); System.Windows.Forms.Cursor.Current = newCursor; } screenDisplay.StartDrawing(screenDisplay.hDC, (System.Int16)esriScreenCache.esriNoScreenCache); IGeometry lineGeom = new PolylineClass(); IRubberBand rubberBand = new RubberLineClass(); if (rubberBand.TrackExisting(screenDisplay, null, lineGeom)) { lineGeom = rubberBand.TrackNew(screenDisplay, null) as IPolyline; } screenDisplay.FinishDrawing(); polyline = (IPolyline)lineGeom;‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ In ArcGIS Pro, i understand how to create overlays and use map tools to create features, but can't quite figure out how to get a drawing from a user from within the code. If there was a way I could trigger a MapTool that would be great too, but can't quite figure out how to get that to work and wait for it in code. I want something like this. //I need something like this to work, and then get result back to use the geometry AddOverlayTool adt = new AddOverlayTool(RowLine); Polyline mPolyline = await adt.startSketch(); //Then I use that line to get the angle and do more work if (!mPolyline.IsNullOrEmpty()) ‍‍‍‍‍‍‍‍

My Code doesn't seem to wait for the sketch from the user?  I call the SetCurrentToolAsync function and i can see that it initiates the tool.  But It just blows right by this line of code after i call it.  I think I am missing something to get the drawing.  My code cannot proceed until I get the drawing from the user.

await FrameworkApplication.SetCurrentToolAsync("XYX_RowTool");

The finished sketch is returned to you in the OnSketchCompleteAsync callback.

That does work in setting the tool to the Line, but I need to do this in my code and get the result. Like I did in ArcObjects. Immediatly after my Feature was created, I wanted a line that represents the Row direction of this polygon (Agriculture field). I basically prompted the user from code to draw a line direction. IGeometry lineGeom = new PolylineClass(); IRubberBand rubberBand = new RubberLineClass(); if (rubberBand.TrackExisting(screenDisplay, null, lineGeom)) { lineGeom = rubberBand.TrackNew(screenDisplay, null) as IPolyline; } screenDisplay.FinishDrawing();‍‍‍‍‍‍‍
