Extrude 2 d image automatically

I have shape file which have lots of polygon each have different height, so I want to upload that file and extrude according to their different height how can I do automatically ,please help anybody.

You don’t specify how you are going to determine the height for each polygon - that is the basic job you are going to have to do. Once you have a height associated with each, it’s as easy as feeding the list of polygons and its synchronized list of height vectors into an extrude component…
