Simulink Editor Defaults Overview

Configure the Simulink® Editor.

These options affect the behavior of all Simulink models. The options relate to the how models appear in terms of the visual theme, the scroll wheel behavior, and the toolbar configuration.

Use classic diagram theme

Cause Simulink diagrams to appear in the Simulink Editor using the visual theme that was used in the Simulink Editor before R2012b.

If you check Use classic diagram theme, Simulink does not display content preview. For details, see Preview Content of Hierarchical Items.

Line crossing style

Change the default display for signal lines that cross. By default, straight signal lines that cross each other but are not connected display a slight gap before and after the vertical line where it intersects the horizontal line. This display style is Tunnel.

The Line Hop format shows a bend where the vertical line intersects the horizontal line. Simulink adjusts the side the bend appears on to avoid overlapping with a block icon. If having the bend on either side overlaps with a block, Simulink uses a solid line.

The None format uses solid lines. This format can provide a slight performance improvement for updating very large models. If you enable the Simulink Preferences > Editor Defaults > Use classic diagram theme preference, Simulink uses a solid line.

Scroll wheel controls zooming

Use the scroll wheel on the mouse to zoom in and out without the Ctrl key modifier. On Macintosh platforms with an Apple Magic Trackpad, if you enable Scroll wheel controls zooming, a panning gesture causes zooming.

Enable smart editing features

Use smart editing cues to perform common model editing tasks quickly. These features appear based on context. Select this check box to enable:

  • Quick insert — Add a block to a model by typing a block name.

  • Tear-off block addition — Add a complementary block from a block tear-off cue. For example, when you add a GoTo block, you can use a tear-off to add a corresponding From block.

  • Multiselection actions — Perform actions from the prompt that appears when you select multiple blocks.

  • Single-selection actions — Perform actions from the prompt that appears when you select a block or a signal.

By default, these features are enabled.

Edit key parameter when adding new blocks

When you add a block to a model, a prompt appears so that you can enter a key parameter. This feature is enabled by default. Clear this check box if you do not want the prompt to appear.
