New User - I have almost completed my first PCB layout. I am not using the schematic editor. I am laying out the PCB manually. When doing the design checks I had a few DRC errors which I figured out and fixed, but I am left with several net errors. Most of the errors indicate faults with single tracks and one error indicates problems with many tracks. This particular error involves tracks associated with power and ground. All the tracks look ok and connect the points that I want to connect, so what causes the errors and how do I fix them? Looking at the board in the Gerber viewer, everything appears ok on both top and bottom layers, so I am not sure what to do next. Thanks.
