I am start to learning adobe illustrator, I want to ask about making drop shadow / gaussian blur of an object in vector ( non bitmap / raster ) type. I found a file and want to use it for study material, but I confuse how / from where this shadow was made. I check the layers are only one object. But if I ungroup it the shadow was dissapeared.
Thanks for the answers and sorry for bad english :)
Effect > Stylize > Outer Glow
to apply it (which will auto-generate a raster image).
