To ensure that certain features cannot be modified at a later time,.you can make them read-only. The dimensions, attributes, scheme, and so on of read-only features can not be modified and are not regenerated when the part is regenerated. However, you can add features to the parts that intersect the read-only features. When you make a feature read-only, Pro/ENGINEER makes it, and all the features that came before it in the regeneration list, read-only.
