Hello Irwin,
Go to View---Options---Category "Tools and View Styles";
select "Filled Edges" from the list box, then UNclick "Draw Entity", click "Apply".
An unrelated question to you and other FEMAP users: Since FEMAP has become part of the much larger EDS, are you concerned that it will (or has) become an unappreciated corporate stepchild, getting little attention and few resources?
