Getting Started with the Unified Cursor-Snap System
Main article: Unified Cursor-Snap System
Altium Designer's PCB Editor already had a well-defined grid system – with visible grids, snap grid, component grid, and electrical grid all working to help you efficiently place your design objects on the PCB document. Now, this system has been overhauled and taken to the next level, with the arrival of the Unified Cursor-Snap System. This system brings together three different sub-systems to collectively drive the way that the cursor snaps onto given sets of preferred coordinates: User-Definable Grids, available in both Cartesian and polar flavors; Snap Guides, that can be freely placed and provide a handy visual cue for object alignment; and enhanced object Snap-Points, enabling placed objects to pull the cursor into position based on cursor proximity to an object's hotspot(s). Use a combination of these features as you see fit, ensuring placement and alignment of your objects in the PCB workspace is a snap!
