Selecting Objects :: Creating a Model (Simulink®)

To select an object, click it. Small black square handles appear at the corners of a selected block and near the end points of a selected line. For example, the figure below shows a selected Sine Wave block and a selected line.

When you select an object by clicking it, any other selected objects are deselected.

Selecting Multiple Objects

You can select more than one object either by selecting objects one at a time, by selecting objects located near each other using a bounding box, or by selecting the entire model.

Selecting Multiple Objects One at a Time

To select more than one object by selecting each object individually, hold down the Shift key and click each object to be selected. To deselect a selected object, click the object again while holding down the Shift key.

Selecting Multiple Objects Using a Bounding Box

An easy way to select more than one object in the same area of the window is to draw a bounding box around the objects:

Define the starting corner of a bounding box by positioning the pointer at one corner of the box, then pressing and holding down the mouse button. Notice the shape of the cursor.
Drag the pointer to the opposite corner of the box. A dotted rectangle encloses the selected blocks and lines.
Release the mouse button. All blocks and lines at least partially enclosed by the bounding box are selected.

Selecting All Objects

To select all objects in the active window, select Select All from the Edit menu. You cannot create a subsystem by selecting blocks and lines in this way. For more information, see Creating Subsystems.
