Thanks all for replies and suggestions. Seems the only way I could really edit the polygons on imported bevelled text from Maya's font list is to triangulate the faces of letters with 'holes' in them and start deleting the new triangulated edges before finally creating nex cuts in the face without getting the same error maessage.

What a bore! Anyway, seems top be working. Just have like twenty more letters to go in this job. Thrilling! Not!!!
