Select the object, then click on Build>Convert to Mesh. This will convert the script or primitive object to an editable mesh.
Thanks ENSONIQ5, I finally figured it out. Now I can use the parametric scripts and modify the resulting object in the editor itself. PS: I may add a new forum on my modeling forum for using Anim8or to create models for Battlezone II Combat Commander; it's basically a moddable video game that people can create 3D models and props for the game. It uses an obsolete XSI model format, but I'm in the process of modifying an X exporter script to output text data that the game can read and load as a game model. Leroy.
