Moving obstacles

To move an obstacle

1 Choose the obstacle toolbar button.

2 Press the C key and select an obstacle.

3 Pressing the left mouse button, drag the obstacle to the new location.

To rotate an obstacle

1 From the Options menu, choose System Settings. The System Settings dialog box appears.

2 In the Increment text box, enter the value (in degrees) by which you want to rotate the obstacle, then choose the OK button.

3 Choose the obstacle toolbar button.

4 Press the C key and select an obstacle.

5 From the pop-up menu, choose Rotate.

Mirroring obstacles

You can display an obstacle as it would appear in a mirror’s reflection using the Mirror command.

To mirror an obstacle

1 Choose the obstacle toolbar button.

2 Press the C key and select an obstacle.

3 From the pop-up menu, choose Mirror. Layout mirrors the obstacle on the current layer or From the pop-up menu, choose Opposite. Layout mirrors the obstacle on the opposite layer.
