The footprint editor opens when a footprint is created or modified. Like the schematic and symbol editors, the footprint editor is a graphical tool that keeps the placement of footprint elements uniform by snapping them to points on a grid.
With the footprint editor, add and manipulate graphical primitives, text labels, pins, vias, and padstacks, and/or adjust the resolution, color, and visibility of the editor grid. Once changes are made, update the current project with any changes to the footprint. Options related to these operations are available on the Footprint menu and the Footprint Draw menu.
