By selecting this grid and clicking the “Properties” button within the grid manager window, you can adjust the parameters.
Notice in the image above that when first opening the grid manager, the only grid listed is the main global board snap grid. Although you can change the parameters of this grid and enable or disable its use, you aren’t allowed to delete it. The “Global Board Snap Grid” is the main default grid in Altium Designer. Use the “Panels” button to access the “Properties” menu, and scroll down for the Grid Manager Once the “Properties” menu is open, scroll down until you get to the “Grid Manager” section in the menu. The key here is to make sure that you don’t have anything else selected in the design session when you click on the properties button, or you will get a menu for the selected object’s properties instead of the board properties. This is the utility that allows you to create and delete additional grids as well as set up and control any grids that you will use during your design session. The core of this grid system is the PCB grid manager. The PCB Grid Manager in Altium Designer for PCB LayoutĪltium Designer provides you with the main default grid, the Global Board Snap Grid, as well as the ability to create additional grids that you can use for specific purposes. This system has several features, and work in both the layout and schematic views. On the other hand, if you prefer working with one main grid there are easy ways to do that too. With this system of multiple grids, you don’t have to constantly reset your main grid. Grids are still important, perhaps now more than ever, and learning to use the grid to your advantage can be a real benefit to you.Īltium Designer has a Unified Cursor-Snap System to give you precise control over your main grid, and the ability to set-up and control many other grids as well. It seems more for designers to have adopted the attitude of “set it and forget it” when it comes to their grids. Before all the different snap and placement utilities that are now available in CAD systems, we used to have to constantly manipulate the grid to place objects at different locations. Altium Designer ® has a well designed grid system that you can use to your advantage in your PCB designs and schematic captures. The grid system in a printed circuit board design CAD program is a great tool for a PCB designer, and it's a system worth knowing.
