Electronic PCB Card Reverse Engineering Polygon
Electronic pcb card reverse engineering is capable of handling complex polygons, but using a number of simpler ones improves performance of the connection tracing code. You also must be careful not to create polygons that touch or overlap themselves. The fabricated board from Electronic pcb card reverse engineering may not look the way you expect if you violate this principle. It is always ok to have two (or more) polygons touch or overlap each other, but not for points within the same polygon to do so.
The great advantage to this new polygon behavior is that simple or complex ground and/or power planes from Electronic pcb card reverse engineering can be easily made with polygons and seen on the screen. If you don’t want this auto-clearance behavior, or you load a layout created by an early version of Electronic pcb card reverse engineering, the old behavior (shorts to all piercing pins and vias) is available. A ‘ChangeSize’ operation (S key) toggles a polygon between the new and old polygon/pin behavior.
With the rectangle tool, defining the two diagonally opposite corners is sufficient, but of course the resulting polygon is a rectangle. Like lines, a polygon can by edited by deleting, inserting and moving the points that define it. Pins and vias always clear through polygons without touching them when first positioned. You must add a thermal with the thermal tool in order to connect pins and vias to polygons when reverse engineering Electronic pcb card.
Thermals can be added and removed by clicking Btn1 with the thermal tool over the pin or via. The thermal tool always places a thermal to polygons on the active layer from reverse engineering Electronic pcb card, so if the tool doesn’t seem to work, it’s probably because the polygon you want to touch is not on the active layer.
