Thanks Sir @Paul_Hossler
Shape is exactly change to my desire custom shape which i inserted in presentation but not the size(ie length, width, height). As a example, I want to change hexagon shape to heptagon shape so I inserted a heptagonal shape & run micros it changes all hexagonal shape to heptagonal shape . It changes only shape but not the exact size of heptagon which I inserted. Is it possible to change the size of hexagonal to the size of heptagonal shape. Sir please look into if some modification in above micros doe the job.
