I note Legon writes:

"As Iversen has pointed out, the Egyptians frequently referred to their works of art as being 'true', and wrote the word maet with the cubit-rod hieroglyph.8"

and in the notes:

"8. Iversen, Canon and Proportions, 7 with n.3. No evidence is cited, and the maet hieroglyph was not identified by Gardiner (Egyptian Grammar, 541). Petrie (Medum, 32) states that the sign is 'commonly recognised as a cubit', at first 'plainly the side view', to which the distinguishing bevel of the end view was later added. Gardiner perhaps failed to grasp the connection between measurement and truth. "

Does anyone know what glyph this is and if it has been added to later code lists?
