Constraints may be used to hide parts of the block model based on some criteria, such as material type or grade threshold.

To add a new constraint:

In Designer tab > Display panel > Block Models section > Constraints dropdown > gear icon.
Click the blue plus icon to add a new constraint.
Rename the label to "HG Only".
Paste the sample formula into the code editor.
Press OK to finish.

Double click in the Available Formulas for code hints.
