To save space, you can remove an empty area from your model in order to decrease the width and/or height of the model. The following procedure shows how to remove space from right to left. The same procedure can be used to remove space from bottom to top.
Procedure
Activate the Insert tab bar.
Click Horizontal space.
In the model window, click the position starting from which you want to remove space, and hold down the mouse button.
Drag the visible end line to the left and release the mouse button at the position where you want to stop removing space. You cannot remove more space than the space that exists between two objects. This prevents objects from overlapping.
The model items positioned to the right of the start line will be moved to the left. The connections are adjusted.
