Components can be moved by clicking on them with the left button and then dragging them around while keeping the button pressed. During the drag, the new location of the components will be shown (as well as the amount of motion), and once the button is released the circuitry will be moved.
While moving, simple design-rules are applied and a warning is shown if the object is in violation. In the example here, the Metal-1-Metal-2 contact is moved down toward the Metal-1 arc and is too close. Use DRC Preferences to control these error messages (see Section 9-2-2). | ![]() |
Another way to move objects is to use the arrow keys. When a node or arc is selected, each press of an arrow key moves that object by one grid unit. If the shift key or the control key is held, then the arrow keys move the object by a block of grid units. A block of grid units is defined in the Grid Preferences (in menu File / Preferences..., "Display" section, "Grid" tab) to be the frequency of bold dots in the grid, initially 10. If you hold both the shift key and the control key, then the distance moved will be a block squared (i.e. initially 100).
![]() | The distance that the arrow keys move is also affected by the Movement commands (in menu Edit / Modes). These commands are also available in the tool bar. |
The Quarter motion command causes the amount to be quartered (so unshifted arrow keys will move by a quarter unit). The Half motion command causes the amount to be halved (so unshifted arrow keys will move by a half unit). The Full motion command causes the amount to be full (so unshifted arrow keys will move by one unit). Note that the Half and Full menu items are attached to the "h" and "f" keys.
To move objects along only one line (just horizontally or vertically but not both), hold the Control key down during motion. Note that holding the Control key down before clicking will change the nature of the mouse action, so you must click first, and then press Control. When editing schematics, this will constrain objects to movement along 45 degree angles.
When arcs are moved by a large amount, they cause the connecting nodes to move with them. However, for small arc motion, the arc may shift within its ports. This can only happen if the port has nonzero area and if the arc has the slidable constraint (shown with the letter "S" when highlighted). These constraints are discussed in greater detail in Section 5-2-2.
