Define object properties

Hello:

You can drag a figure that can generate a text field in the

characteristics that can define the object, drag the alien example

and when released will open a properties box that asks me some data such as length, etc. and send it through ajax and make calculations in a script, you can do this and say if I drag more than one definition for each object its own characteristics

the example I'm working on is this

I appreciate if you can help

regards
