FLT files

I have a few questions as a new user of Carlson Software.
1. Is it possible to create (draw) 3d faces from an existing FLT file from a
previous session?
2. Is it possible to edit 3d faces in a drawing, then just update its FLT
file?
3. Is it possible to use an existing FLT when prompted for selection in the
"triangulate and contour" command?
Thanks in advance.
