Adding and Deleting Shapes on Nets

The Add Shape To Net command lets you add selected shapes to nets that are attached to pins. An instance or mosaic can be added to a net as long as there is at most one terminal on the net. An instance cannot be added to a net if it contains instTerms. A shape cannot be added to more than one net. Terminals and nets are not deleted when the physical pin shape associated with them is deleted.

The Delete Shape From Net command lets you delete selected shapes from a net. Terminals and nets are not deleted when the physical pin shape associated with them is deleted.

Adding Shapes to a Net

To add a shape to a net:

1. On the layout canvas, select one or more shapes.
2. Choose Connectivity – Nets – Add Shape.
   The Add Shape to Net form appears.
   
   
3. Do one of the following:
   • To specify the net based on the selection, select the Auto check box. For each shape, the software looks for a pin that overlaps the shape and adds the shapes to the net.
   • To specify the net manually, turn Auto off and type the net name.
4. Click OK to close the form and add the shapes to the nets.

When there are zero-area dot pins on the edge of the shape to be added, the pin is used only if one of its access directions points toward the center of the shape.

1. Select one or more shapes to be removed from a net.

   The Remove Shape From Net form appears.

4. Click OK to close the form and delete the shapes from the specified net.
