# Can we extrude or pad a point in catia??

Hi, I know this sounds little odd. But I was puzzled with this question. A line can be extruded as well as pad can be given, but can we do the same to a point in catia, if NO, why?? I did try, but I was getting an error of standard geometrical element please change it to construction element. I want to understand why it is not possible if the answer is NO..

Hi Karthik, I will try to explain it. You can only extrude a sketch which has some dimensions. When you are extruding a solid you have to make a closed sketch which has some finite area and no open ends. When you are extruding a line it will automatically change to surface extrude because a line does not have an area. In case of a point it has neither length, breadth and height and obviously no area.So it will not produce a result it has no dimension only you can place a point by its x and y position.that's the location or coordianates of a point nor its dimension. It cannot be extruded because it will not produce a finite result neither a solid nor a surface. Do you get my point?
