I believe many people have encountered unknown pin and failed to add class member when using dxp and AD, after experiments, we found that creating a new PCB can solve these problems. This is also a common practice on the Internet. However, it is time-consuming and effort-consuming to create a PCB by giving up the first half of the layout and wiring. Therefore, I was thinking that since an error was reported, there was definitely a solution, so I studied and found the following solution. Hope to help you.
This prompt is displayed because the current PCB already contains net. You only need to delete all the net on the current Board and then import it. You do not need to worry about it now. Click to continue.
Same as above.
How to solve the unknown pin problem is actually very simple. As mentioned above, you only need to delete all the net on the current PCB. Follow these steps.
After deletion, import the file again and you will find that the problem from figure 2nd to the unknown pin has been solved. There will be no more prompts or red X.
The following describes how to solve the problem of adding component classes errors. The prompt is failed to add class member: XXX.
See the following figure for solutions.
After deletion, there will be only one all component classes left, and then re-import will find that the problem is solved perfectly. Hope to help you. Huarana (Such as Xia Hua)Original, reprinted please note.
