Hi, I opened a file and the FeatureWorks window showed up. It states "Following features are not supported by FeatureWorks". In a box, "Surface-Imported1" is listed. There are two options: "Delete unsupported features with child features." (checked by default) and "Map unsupported features as thicken features." I have no idea what they are. Could you please let me know what is the best course of action in this case?
