Most blocks have parameters and initial conditions associated with them that let you set attributes that are specific to the block. You define and change parameters through a block’s Properties dialog box. When you display a Properties dialog box while the simulation is running, the simulation halts. After you close the dialog box, the simulation is immediately updated to reflect the change.
To access a block’s Properties dialog box
•Right-click the block, or choose Edit > Block Properties and click the block.
Note: Right-clicking a block is a shortcut for accessing the Properties dialog boxes for most blocks. For button, compound, and userFunction blocks, hold down the CTRL key and right-click to access their Properties dialog boxes.
