PADS drawing board, what are the advantages of flat area compared to copper plating or copper pouring? What are the special requirements for making a flat area when copper plating or copper pouring can be done?

I think the results are consistent. In some cases, a certain area may need to be covered with copper, but simply laying copper or setting the rules cannot meet this requirement. For example, if there is a chip area, if you set copper laying, it will generally be laid over, leaving a certain gap. But if you want a heat dissipation pad, it is obviously more convenient to just make a plane.

The plane you are talking about is copper laying? I am talking about the inner layer...

Can't the inner layer also be made of copper or copper ring? Why do we need a plane area?

The Top and Bootm layers are divided by copper inner layers using plane areas. The inner layer is a negative film. When setting the properties of the layers in the early stage of the software, the software can also set the properties of the inner layer, such as the power layer properties. You can also choose other properties such as NO PLANE

When the inner electrical layer attributes determine the mixed layer, the area should be divided by plane area or other methods.

I don’t know what you are talking about. . .

I mean that the copper plating and copper pouring tools can also be divided piece by piece.

I don’t know what negative film is.

Isn't a negative film the reverse side of a positive film?

It has nothing to do with the positive. The negative is similar to the seal carving.
