sketch support indicates where is the sketch plane is lying on. and also you can change sketch support when you need.

Suppose you have created a sketch on XY plane and applied the pad or whatever command to make it solid ,Later on you realized that the part's sketch should be in ZX plane , Then you can just change the sketch support from XY plane to ZX plane ,and your problem is resolved.

: Sketch support can be XY ,YZ, ZX plane or any flat face of a solid .
: Sketch support must be planar i.e you can select the flat face of solid as a sketch support ,but sphere,conical portion, round ,or any other irregular surface can't be a sketch support
