>>
Click once on the editor after crossing the bottom-left vertex.
|
Let us move this cursor vertically, towards the bottom-right vertex of the board.
Click once slightly below bottom-right vertex.
|
Pcbnew window:
|
Similarly, we will draw a rectangular ground plane outline around board outline.
|
Pcbnew window:
Hover cursor over ground plane outline >>

Please make sure to click inside the board outline.
| |
Pcbnew window:
Click on Margin layer from the right toolbar
|
Click on Margin layer.
|
Pcbnew window:
Click once the top-right vertex of the board layout
Drag the cursor towards the bottom right vertex in a straight line.
|
Click once on either vertex of the board layout.
I have chosen the top-right vertex.
Let us drag the cursor towards the bottom right vertex in a straight line.
|
Pcbnew window:
Hover cursor over horizontal dimension
|
We will perform similar steps for placing horizontal dimension of the layout. |
