This plot is used to visually assess whether or not it is valid to use the single value recommended shrinkage allowance, as reported in the analysis log, across the entire part when cutting the mold.
Green areas on the shrinkage check plot represent regions of the part where it is acceptable to apply the single value recommended shrinkage allowance. If all the critical dimensions on the part model lie within the green regions of the plot, it is valid to use the total recommended shrinkage allowance for the whole part.
Red areas on the shrinkage check plot represent regions for which you cannot use a single value of shrinkage. This is because the shrinkages in these regions lie well outside the single value validity range.
Yellow areas on the shrinkage check plot represent regions for which you may still be able to use a single value of shrinkage, but you need to examine more carefully the shrinkage variation across the part to determine whether a single value can confidently be used.
