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?
Thanks you soumya, my doubt is clear now..
Hi karthik, I understand your point. But I would say that by default if you pad a closed sketch it will surely be solid and by default if you trying to pad a open sketch it will turn to surface and extra thing is you have to add thickness for making it solid. I assume you are using catia because in catia solid extrude is called pad but if you try other cad softwares like solid works or creo or proe you will notice that the pad option in catia often called extrude solid in other software. Are your doubts clear?
Hello soumya, thanks for the explanation, but I have a doubt, if I PAD a line or an open profile by giving Thickness option, isn't it a solid body. How can we call it as a surface. Because I am doing PAD not EXTRUDE in surface workbench.
Hi Karthik, you can create line by a point (ie. by extrude/pad/drag) in catia by using line definition (line type as: point-direction) in reference tool bar. please follow this tutorial you will come know.
