Hi Liqun,

Usually all the block mask parameters are completely in control of the developer and there might be internal callbacks which might be overwriting your visibility settings.

Also, what you are seeing in the initialization section is a preinitialize-callback which usually exists for most of the blocks, to control the mask params & may be sometimes license & other checks

Hope this clarifies

Raju.

Hi Raju

Thank you for your answer.

I try to comment the function in the initialization section with % symbol. The result still is that the mask appearance can't change. So the mask appearance may be completely in control of internal callbacks, such as Variable Orifice block and Constant Source block.

As Raju commented, the icons for library blocks are in control of the developer. In recent versions of Simscape, there is usually a .svg file of the same name as the block .ssc file, in the installation folder, and the .svg file is the icon definition. Changing those is possible, at your own risk, but it'll require changes to your installation folder.

You can always put another mask on though. Since it's your own mask, you can change its appearance whichever way you want. However, you have to do this for every block you want to change.
