Summary

This dialog allows the designer to quickly set a different interval size for the Snap grid. The Snap grid pulls the cursor to the nearest point on its defined grid. Depending on how the dialog is accessed, the required value can be applied to both Step X and Step Y, or just Step X, or just Step Y.

Access

The dialog can be accessed from both the PCB Editor and PCB Library Editor in the following ways, depending on how the Snap grid is to be changed:

  • Change both Step X and Step Y - use one of the following:
    • Choose the View » Grids » Set Global Snap Grid command, from the main menus.
    • Right-click in the workspace, and use the Snap Grid » Set Global Snap Grid command from the context menu.
    • Use the Shift+Ctrl+G keyboard shortcut.
  • Change Step X only - right-click in the workspace, and use the Snap Grid » Snap Grid X » Set Snap Grid command from the context menu.
  • Change Step Y only - right-click in the workspace, and use the Snap Grid » Snap Grid Y » Set Snap Grid command from the context menu.

Options/Controls

Use the field in this dialog to set the grid interval as required.

The entered grid size is reflected at the left-hand side of the status bar. If the grid was set globally (for both Step X and Step Y), then a single entry for the grid value will be displayed. If the grid was set for Step X or Step Y individually, the individual grid steps will be displayed. The current step sizes for the Snap Grid can also be verified in the Cartesian Grid Editor dialog, when accessed for the Global Board Snap Grid, through the main Grid Manager dialog.
If entering a snap grid setting without specifying units, the entry will be in the default measurement units selected for the design, as determined by the Measurement Unit setting in the Board Options dialog (Design » Board Options). Specifying units when entering the value (mm or mil) will change the default measurement units for the document to those specified, if not currently the default.
