Copying a Twin Builder Design into Another Design

To copy an existing Twin Builder design into another design for the first time:

In the Project tree, right-click the icon for the design you want to copy.
Select Copy.
Open the design into which you want to copy.
Do either of the following:

On the Edit menu, click Paste.
On the keyboard, press CTRL+V.

The Synchronize Design dialog box opens.

Specify how the circuit you are copying will be associated with the target design by doing one of the following:

Select Make Copy to create an independent subdesign, which will not be affected by changes to the original.
Select No copy - use instance of original to keep the copy linked to the original, so that changes to one will affect the other.

Click OK.

Within the schematic window, the cursor is associated with a symbol for subcircuit placement. To place the subcircuit, click at the desired location.

Hint

You can rotate the subcircuit symbol before placing it by repeatedly pressing R on your keyboard. Each press rotates the component 90º counterclockwise.

If there is already a subdesign in the parent schematic, there is an easy way to create an independent copy. Right-click the subdesign symbol and select Copy as New Design. Then paste using the menu command, or CTRL+V. In this case the Synchronize Design dialog box will not appear.

Note:

• To ensure electrical connectivity among schematic elements, the pins of placed subcircuit symbols snap to a 100-mil (2.54-millimeter) grid. This snapping cannot be turned off, and the spacing of the connectivity grid cannot be adjusted.

When copying components, you can also use Copy to Clipboard in the right-click popup menu to copy and paste components into other applications.

The first time you place a subcircuit in a design, an entry for it is added under the Project Components heading in the Project Manager Component tree.

To save time as your work progresses, you can place new instances of the subcircuit on the schematic:

Double-click its Project Components icon.
Right-click its Project Components icon and select Place Component.
Drag its Project Components icon.

If Multiple Placement is turned on for components in Twin Builder’s Schematic Options dialog box, click additional locations to place additional subcircuit instances.

To stop placing subcircuits during multiple placement, do any of the following:

Press Enter, the spacebar, Backspace, or Esc>
Right-click and select Place and Finish, Finish, Cancel, or Back.
