Parent page: Schematic Commands

The following pre-packaged resources, derived from this base command, are available:


Applied Parameters: Action=ProjectSystemParameters

Summary

This command is used to access the Sheet Numbering for Project dialog. This dialog allows you to quickly number the constituent schematic sheets in the active design project. Sheet and Document Numbering allows you to take control over the sheet designation and store them as parameters within the respective schematic documents. Special strings (=SheetNumber, =DocumentNumber, =SheetTotal) can then be used to expose these values on the sheet (in the sheet's title block, for example) as text objects.

This command relates to the numbering of the logical sheets. To number the compiled sheets (the physical instances of sheets), use the Annotate Compiled Sheets command.

Access

This command is accessed from the Schematic Editor by choosing the Tools » Annotation » Number Schematic Sheets command from the main menus.

Use

After launching the command, the Sheet Numbering for Project dialog will open. Use the controls available in the dialog to define sheet and document numbering as required. If your organization has a specific number or naming system that cannot be automated through either the Auto Sheet Number or Auto Document Number controls, custom sheet names and numbers can be written directly into the SheetNumber or DocumentNumber fields.

Tips

  1. Sheet or Document Numbers cannot be configured for Device Sheets when they are read-only (default state) and will be cross hatched in the Sheet Numbering for Project dialog to indicate they cannot be updated. When Device Sheets are set as editable, the cross hatching is removed and Sheet and Document Numbering can be configured as normal.


Applied Parameters: Action=SetSnapGrid

Summary

This command is used to set the snap grid to a user-specified value. The snap grid value defines the alignment grid for manual movement and placement in the current document.

Access

This command can be accessed from the Schematic Editor and Schematic Library Editor by:

  • Choosing the View » Grids » Set Snap Grid command from the main menus.
  • Choosing the Set Snap Grid command on the Grids drop-down () of the Utilities toolbar.

Use

After launching the command, the Choose a snap grid size dialog will open. Use the dialog to enter the required value for the snap grid.

Tips

  1. The entered grid size is reflected at the left-hand side of the Status Bar and also in the Snap Grid field in the General section of the Properties panel (when accessed with no objects selected in the design workspace).
  2. In the workspace, cycle forward (G) or back (Shift+G) through predefined grid settings. The settings available are determined by the chosen presets as defined on the Schematic - Grids page of the Preferences dialog and the current measurement system in force (Imperial or Metric). If you change the grid size in this manner, your entered setting (through the Choose a snap grid size dialog) will be lost since cycling only involves the currently chosen preset interval settings.
