Summary

The Favorite Interactive Routing Widths dialog allows you to predefine favorite track widths for use when interactively routing a board when using the Interactive Router.

When you run the Interactive Routing command and click to start routing, a series of track objects are created from the nearest pad up to the current cursor location. The width of these tracks is either taken from your preferred width or the applicable routing width design rule. The former is referred to as User Choice and it is the Favorite Interactive Routing Widths dialog that provides the cornerstone of this feature.
When using the User Choice feature and predefined routing width, you still have the full protection of the rules system. If a chosen predefined routing width is outside the applicable min-max rule setting, the width will be clipped back to the minimum or maximum, whichever is appropriate.

Access

The dialog is accessed by clicking the Favorite Interactive Routing Widths button in the Favorites region of the PCB Editor - Interactive Routing page of the Preferences dialog.

Options/Controls

  • Widths Grid - the main region of the dialog presents a listing of all currently defined interactive routing widths. For each defined width, the following information is presented:
    • Imperial - the width in imperial units (mil).
    • Metric - the width in metric units (mm).
    • System Units - the preferred system units when using the defined width (Imperial or Metric).
Entries without shading indicate that the preferred system units will be used when those widths are chosen. The board units are switched automatically.
The display of the Imperial, Metric, and System Units columns can be toggled through commands available on the region's right-click menu. These main columns can also be re-ordered by dragging a main column horizontally; vertical green positional arrows indicate a valid position. Data can also be sorted by the various sub-columns.
Double-click an entry to access the Preferred Routing Width dialog in which the value for the width can be changed as required.
  • Add - click to open the Preferred Routing Width dialog to add a new routing width to the list. 
If you enter a value with no units, it will default to Imperial preferred system units. To control the preferred system units used for the width, ensure to specify the units (especially if Metric is desired).
  • Delete - click to delete the currently selected routing width(s) from the list.
The grid supports standard multi-select techniques (Ctrl+click and Shift+click).
  • Edit - click to open the Preferred Routing Width dialog to edit the currently selected routing width. 

Right-Click Menu

The following commands are available from the grid's right-click menu:

  • Add - click to open the Preferred Routing Width dialog to add a new routing width to the list. 
  • Delete - click to delete the currently selected routing width(s) from the list.
  • Show Imperial - use to toggle the display of the Imperial column and its data.
  • Show Metric - use to toggle the display of the Metric column and its data.
