Hi there,

Thank you for your post! I think using a layout grid is an effective way to establish a coordinate grid. Generally, layout grids are instrumental in aligning objects within a frame, offering a clear visual structure that enhances the overall design. By leveraging this feature, you can easily create a coordinate grid.

For a deeper understanding of layout grids, including their various applications and settings, you might find this resource from Figma quite helpful: https://help.figma.com/hc/en-us/articles/360040450513-Create-layout-grids-with-grids-columns-and-rows
