Closing a Freehand draw into a polygon

[jonataspovoas]

Hi,

I'm developing an area measure tool, and I need to complete a freehand draw drawn by the user into a polygon to calculate the area and show back.

How do I do it?

Are you using the Draw class and listening to the DrawComplete event?

You just need to convert the Polyline to a Polygon, creating a Ring for each Path and add all points. Then add the start point to the end to complete the draw.

After that submit the Polygon to the Geometry Service for Area and Length.

You can use a combination of these samples:
