How to check if Constant and Gain blocks are too small

How can I write a script to identify all Constant and Gain blocks in a Simulink model that are too small to fully display their values?

Currently, I compare the actual block size (obtained via

get_param(block, 'Position')

) with an estimated required size. This estimation is based on the length of the Value parameter multiplied by an assumed pixel width per character. However, this approach leads to inaccuracies, especially for blocks that are borderline too small.

Is there a more robust or straightforward method to determine if the block size is adequate?

While I probably would do a similar approach than you, I wonder what the underlying reason could be for this happening in the first place.

The issue arises from the inaccuracy of the current method. When setting the required height and width to a specific estimation, I encounter corner cases where, for example, the Gain blocks are on the verge of being unreadable but aren't quite there yet. However, the code returns a failure, incorrectly indicating that the block is already unreadable. This happens because the estimations are not accurate enough. I'm looking for a better way to solve this.

There is currently no documented way to do this in a more robust way. I agree with @Andreas Goser that it might be good to better understand the root cause.

If you can use undocumented features, please contact our Technical Support team via an official case and let us know your use case and we can check if we can send you a better way to do that.

Also please share the full use case with us (if you want to code a Model Advisor check for example).
