1 SHIFT + s this shortcut can highlight the current layer and make other layers gray, see:
2. Hide a specified layer
In the lower-right corner of the figure, right-click and an option bar will pop up. Select hide layers to select the layer you want to hide.
3. Right-click any position in the PCB diagram of the specified layer in view deployments and choose Options> boardlayers & colors.
On the board layers and colors, you can select which layers are displayed and which layers are hidden.
4. The effect of displaying only a single layer is very obvious. For details about settings and effects, see
5. transparency settings
This feature does not seem to have been seen in the earlier alicloud designer, or in the options interface above, there is a transparency setting.
Relatively speaking, I like this function very much. If it does not completely see other layers, it can highlight the current layer, but it is troublesome to set back and forth.
