I have designed a board with a small switching power supply, doing the placement of components and adding the 3D models when not already available. However, I want to fill some areas of the PCB with copper, following the layout recommendations found in the switching power supply IC datasheet. I successfully succeeded in adding a ground plane on the back side of the board. However, when I try to fill ground areas on the front side, a strange phenomenon occurs: when I try to create and fill separate areas, the filling tool fills some of them while refusing to fill others, depending on which of those ones I create first. The same thing happens I draw a big area, encompassing all the regions I am interested to fill: it does not fill all the areas which I succeed in filling separately. What should I try? Thank you all in advance.
