Recently I purchased the switching power supply design course but I have some problems in the course.

First of all, after I followed the videos and finished the schematic drawing. I compile the schematic document but I found several warnings. It wrote "Floating Power Object" as shown in the following screen shot:

I don't know whats wrong with my drawing, the problems did not solved even I deleted and re-draw the GND symbol. There are several GND and power symbols contain this warning.

Another problem is that when I updated the PCB document, one of the items showed error as shown in the following screen shot:

I don't know whether this error is related to the warnings when compiling the schematic document. Please help to answer my questions, thank you very much!

Dear friend
I guess if the +5 V and the GND are a bit distant and rooted, the problem is solved

Thanks alferdvidal!!!

I have solved the "Floating Power Object" warning by re-placing the GND and VCC symbols and now there is no warning after compiling the schematic file. For the problem of updating PCB document, I removed the net name of the GND symbols in the schematic. After I name "GND" as the net name of each GND symbol, the updating has no problem
