Editing the attributes of multiple PCB layers and vias
You can edit multiple PCB layer or via physical properties at the same time, from within the PCB Stack physical property.
For a selected PCB layer, you can modify:
Trace and dielectric material
Thickness
Trace coverage
Thermal conductivity
Material orientation
For a selected PCB via, you can modify the layers from which the PCB via starts and ends, via trace and dielectric material and trace coverage.
The following table describes the icons that can be displayed in front of each property in the Multiple Edit PCB Layer or Multiple Edit PCB Via dialog box.
| Icon | Hover text | Description |
|---|---|---|
| No Change | Indicates that the value currently defined for this property is the same for all the selected layers/vias modeling objects. | |
| No Change | Indicates that the value currently defined for this property is different for two or more of the selected layers/vias modeling objects. | |
| Apply Change | Indicates that the change you made for this property is applied when you click OK. | |
| Lists the properties currently defined for the selected layers/vias modeling objects. |
