Applied Parameters: None

Summary

This command is used to place a Manual Junction object onto the active document. A junction is an electrical design primitive. It is a small circular object used to logically join intersecting wires, buses, or signal harnesses, on a schematic sheet. A manual junction allows you to create a connection between crossed wires/buses/signal harnesses, by placing the junction at the crossing point. This is different from a Compiler generated junction, which is automatically inserted when two wires/buses/signal harnesses are connected in a T-type fashion, or when a wire/bus/signal harness connects orthogonally to a pin or power port/bus power port..

For detailed information about this object type, see Manual Junction.

Access

Manual junctions are available for placement in the Schematic Editor only, by:

  • Choosing Place » Manual Junction from the main menus.
  • Right-clicking and choosing Place » Manual Junction from the context menu.

Use

After launching the command, the cursor will change to a cross-hair and you will enter junction placement mode.

  1. Click or press Enter to place a junction at the cursor position.
  2. Continue placing junctions or right-click or press Esc to exit placement mode.
Press the Tab key during placement to access Junction dialog, from where properties for the manual junction can be changed on-the-fly.

Tips

  1. Display of the connection status of manual junctions can be controlled from the Schematic - Compiler page of the Preferences dialog. If the Display option is enabled each manual junction that is creating a valid connection is back-colored, in the color defined by the Color option. Note that the default Size of the Connection Status display feature is Smallest, which is the same size as the default manual junction size. This means the back-color will not be visible, unless the Size is set to Small or larger.
  2. For information on how a placed manual junction object can be modified graphically, directly in the workspace, see Graphical Editing.
  3. While attributes can be modified during placement (Tab to bring up associated properties dialog), bear in mind that these will become the default settings for further placement unless the Permanent option on the Schematic – Default Primitives page of the Preferences dialog is enabled. When this option is enabled, changes made will affect only the object being placed and subsequent objects placed during the same placement session.
