You can insert an empty area into your model. The following procedure shows how to insert space from left to right, for example, in order to create space between two objects arranged directly beside each other. The same procedure can be used to insert space from to top to bottom.
Procedure
Activate the Insert tab bar.
Click Horizontal space.
In the modeling area, click the position starting from which you want to insert space (from left to right), and hold down the mouse button.
Drag the visible line to the right and release the mouse button at the position where you want to stop inserting space.
The model items positioned within the area indicated by the start and end lines are placed to the right of the end line. The connections are adjusted.
