It’s possible to rely exclusively on your default grid for all aspects of component placement, trace routing, and mechanical or special object placement. However, reliance on one grid size requires frequent step size changes, as well as a unit of measure change, and possibly even board origin location changes, in order to achieve all required grids. This is where customizable grids come in to resolve this complicated and manual process.
Using Grids to Speed Up Your Design Process
Placing components of a specific grid can help speed up the component placement and alignment process. It can also help achieve optimal component density. As most component footprints are defined in millimeters, one or more dedicated, user-defined metric grids can be defined to accommodate component placement. Such grids can be specified to be active only when in component placement mode, and to remain disabled and invisible while routing traces.
