Create Block Masks

Create customized appearance, create user–defined interface, encapsulate logic, and hide data for subsystems and custom blocks

金宝app^®enables you to create block masks. A mask is a custom user interface for a block.

By masking a block you encapsulate the block diagram to have its own parameter dialog box with its own block description, parameter prompts, and help texts.

You can mask an independent custom block that you can reuse as unique blocks like those defined in Simulink.

To know about creating a block mask, seeCreate a Simple Mask.
