Tips Copy Link Copied
- The X Size (All Layers) property is only defined for simple via objects - those with their Stack Mode property (as seen from a List panel) set to Simple. When viewing the properties for a via through the Properties panel, this relates to the Simple option being selected, in the Size and Shape section.
- When viewing the properties for a selected via in the Properties panel, the X Size (All Layers) property corresponds to the Diameter field, in the Size and Shape section.
- This function is an alias for the ViaSize function.
