I am messing around with this and I have added further variables and some click events to move directly from one object to another.

I need to figure out how to perform a click event on a polyline to load the vars associated, but I can't for the life of me figure out how to do it programmatically. I need to cycle through the created items and pull the wanted data.

First of all, thanks for this code, it was really helpful on what i had to do.
I have messed around with it a little bit and this is what i came up with: I have changed the map type, changed the position of a few things and added a confirmation box when the button "Delete a selected shape" is clicked, I hope this was helpful to some of you.
(the code is in the link bellow)

Thanks for the very helpful code.
I would like to ask if there is a way to view the coordinates of the position of the mouse cursor while you are drawing.
Thanks

Thanks buddy, I was looking for this for the past few days. Awesome work. One more thing I would like to ask if we can get the coordinates while drawing and, when shapes are moved to new location. Would be very helpful ! Thanks again

How we can manage predefined shapes. Like change shape color, edit and delete the shape etc.
How we use "setSelection" methods for exits shapes.

Thanks a lot,
One more question can you help me with how can I save CIRCLE, RECTANGLE, POLYGON drawing data into database and load when my map is fully loaded.

@azaddeveloper not natively with the drawing manager. I created a tool to help https://github.com/knownasilya/google-maps-drawing-tools

Was someone able to figure out how to get the coordinates of the shape as you are drawing the shape?

@Deepp805 you'd have to manually draw the polygon and then add it to the drawing manager, example here: https://github.com/knownasilya/google-maps-markup/blob/master/addon/components/google-maps-markup.js#L213
