Blender Create Polygon Tool for Maya users.

The alternative for the Create Polygon Tool in blender is the “Duplicate or Extrude at 3D Cursor” function in Blender.
This will add a new vertex at your cursor’s location mimicking the Maya Create Polygon Tool.

To use it you must be under “Edit Mode”.
Shortcuts for the function are “Ctrl + Middle Mouse Button” for the Maya Preset and “Ctrl+ Left Mouse Button” for the Blender preset.
If the shortcuts don’t work, you can find the function in User Preferences -> Input -> search for “Duplicate or Extrude at 3D Cursor” and change the shortcut as you please.

I’m adding this post since the top result in google is a locked thread that doesn’t mention this option.
