In the context of Sprint-Layout, a macro is essentially a pre-drawn component footprint. Instead of drawing four pads and a silk-screen outline for a bridge rectifier every time you need one, you simply drag a "Macro" file onto your workspace.
One of the reasons Sprint-Layout is so popular in the hobbyist community is the abundance of free, user-made macro packs. You can find massive libraries online containing thousands of specialized footprints. To add these to your software: Download the .zip or folder containing the .lmk files. macros sprint layout 60
Use the pad and drawing tools to create the footprint exactly as per the manufacturer's datasheet. Ensure your grid is set correctly (usually 1.27mm or 2.54mm for through-hole). In the context of Sprint-Layout, a macro is
Use the Spacebar while dragging to rotate the component in 90-degree increments. How to Create Your Own Custom Macros You can find massive libraries online containing thousands
