How does Altium Designer make the keepout layer only take effect on the top layer?


1. Keepout is a rule of graphic steps as follows:

1. Switch to the Keep-Out layer

2.Place->Keepout-Fill/Solid Region

Use Fill or Region to draw keepout directly
Fill/Solid Region

3. Select the drawn keepout, and change Restricted for Layer to Top Layer in the properties

Traces
you can see that keepout is only effective for the top layer, and the bottom layer can still be routed.

2. Keepout is an irregular shape:

1. Draw the outline of the keepout on any layer. If it is on the Keep-Out layer, only the tools in Place-Keepout can be used to draw the outline.

5. Switch to the Keep-Out layer, Edit->Paste Special, select Paste on current layer, and click Paste. In this way, a Keepout-Region is obtained instead of a normal region.
