Draw Widget - Measure in Nautical Miles

Question

Has anyone attempted to create a custom Draw tool that could measure in Nautical Miles?
I've searched Hi and Low through the documentation and it doens't appear to be a configurable option.
Does anyone know why that may be?

Thanks for any input,
Susan

Sure, the enhanced DrawWidget allows you to configure whatever distance, area, and point units you want. Just need to add the converion option to the eDrawWidget.xml. http://www.arcgis.com/home/item.html?id=91a0014160fc4a9caadc2c7fd7089c1b I use this in my xml for knots as my data is in meters.

Susan,

Do you have the ability to amend the source code? If so, you'll see it's fairly straight forward to add in the conversion for nautical miles. You should be able to see where you would need to add the code:

https://github.com/Esri/arcgis-viewer-flex/blob/develop/src/widgets/Draw/DrawWidget.mxml

In the function basewidget_widgetConfigLoaded there is a case statement with the units of measure listed and there is an array list near the bottom with the same again
