I am trying to create a model of the outer surface of a segment. I have tried wrap solidify extension, surface model module > model maker and hollow. The only one that worked in making a surface model without internal structures is wrap solidify. However, it also creates an abnormal surface attached to the segment as shown in the images (The green mandible is the segment and the yellow mandible is created after using wrap solidify extension). Please let me know which tool to use to create a surface model.
