Zooming and Panning in Simulink R2012b

As we highlighted recently, Simulink R2012b has a ton of new features. During the next weeks, we will try to provide as much details as possible on all this new cool stuff.

For this week, I will start with the basic of navigating models.

Zooming

In R2012b, zooming is a lot more dynamic with the mouse wheel. Here is a short animation where I highlight all the possible ways to zoom in R2012b:

In case you have problems getting used to scroll wheel zooming, you can go to the Simulink preference and uncheck the Scroll wheel controls zooming option:

Panning

Before R2012b, panning could be done using P or Q in combination with the left mouse button. The result was equivalent to moving the scrollbars at the top and bottom of your model. I am not sure why, but I almost never used this feature.

In R2012b, the panning is easier to access, with the middle mouse button or a combination of the spacebar and left mouse button.

The panning is also more powerful. It allows you to increase the dimensions of the model in any direction:

My personal experience

I need to be honest with you... getting used to Simulink R2012b was a good challenge for me.

Before R2012b, the 4 most used keys on my keyboard were R, F, V and 1. Every time I opened a new model I was using those to zoom in, zoom out or zoom 100%.

I tried the new panning and zooming for a few weeks. After some frustration because I ended up zooming instead of scrolling, I tried disabling the scrolling zoom. That quickly made me realize that using the scroll wheel to zoom is very useful and after just a few hours I re-enabled the option.

About the panning, it forced me to develop new muscles. Since I was never using the middle button of my mouse, that gesture initially felt weird, like if it was requiring a lot of efforts in my finger to push that middle button.

After a few months using Simulink R2012b, I now try to use the middle mouse button to pan everywhere and end up saying to myself: Why is that software not panning with the middle button?

Now that I have been using Simulink R2012b for a few months, I absolutely love it. Everything is more easy.

The other day I had to test something in R2012a and when I opened the model I asked myself: How was I satisfied with this old interface?

Now it's your turn
