Worth a thousand words image, and for that I created 4 videos of how the process is done.
In the first video we go to the tab ARES and there chose the grid, like what we do is a few jumpers, as we look at the tab on the left pads, look what the dimension and place them after we looking at distance between pads, to whet the component. We conducted outside the component that will be the area occupied outside.
In the second video we number pads, we can put that layer we want to be in this case to be a jumper put all but we can choose to just be in the botton for welding. After numbering create the package with the features of our component. And we keep it in the library.
In the fourth video we do is assign the drawing of schematic the package, so tanor select all the symbol we give right click and give to Make device, we name, add the package and we match the pins accordingly .
It is also convenient to add the reference cost and where we bought because in the bill may see this data giving a touch of professionalism to our work. It is important to follow the steps of the video because for the price may have problems with decimals, once we have as we continue the process and store it in the library.
