Straight Duct over 60" overriding auto length specifications

Why is my straight duct length which should be 56" changing to 20" long on anything over 60" wide? see screencap

Hello Christopher,

if Machine Cut, the Straight Auto-Length can be read from either the Fittings or Straights spec section.
You can change it in the Database > Fittings > Pattern Options > General >>> here set Machine Cut Straights to "Straights".

Please let me know if that helps.
