Manufacturing joint functions return information to EngView about the current state of a manufacturing joint in a drawing. For example, the function mfjlongside("left") checks if the manufacturing joint is on the long left side of the structure and returns Yes if this is true.
By using these functions, you can create universal resizable structures just by switching the place of a manufacturing joint. Each time you do this — for example, when you change the manufacturing joint from the glue flap of the long to the one of the short panel — the structure's dimensions recompute automatically as a result of the role of the functions in the parameters' expressions.
Place a function into the expressions of parameters and/or in a component's conditional visibility. Depending on the case, the functions return 1 (also true / yes) or 0 (also false / no). EngView then uses these data to recompute the structure.
You can use a manufacturing joint function in a design frame formula in the standard pattern:
| Pattern | $OneUp1.function$ |
| Example | $OneUp1.mfjlongside("left")$ |
Each function below corresponds to a combination of the settings of a manufacturing joint. When the settings that you see are selected, the function returns 1 (also true or yes).
NOTE: Unlike all other properties in this section, this function returns a number, not a "yes/no" value.
