Create Polygon By drawing 1 line connecting existing Polygons.

Hey All,

Hopefully a basic question, But how can I draw 1 line between multiple existing polygons to create a new polygon where no polygon previously existed.

Example attached to hopefully clarify. In the drawing the red polygons 1, 2 and 3 exist. I want to draw in the blue line to create polygon number 4 with all of the same fields and on the same layer as 1, 2, and 3. What is the process to accomplish this?

Thanks David,

I don't think this will work in the use case I have as I don't see where it shows how I would draw the blue line to complete the missing boundary. Am I missing something?

Ah yes apologies.

The auto complete polygon tool on the Create editing template should work for most use-cases. if you do end up with so extra multipart polygons you can easily delete them out.
