1. A method comprising:
performing vacuum securement of an object to a forming tool by:
locating the object on the forming tool;
covering at least a portion of the object with an impermeable membrane, wherein at least a first portion of a perimeter of the impermeable membrane is in contact with a surface of the forming tool, and wherein at least a second portion of a perimeter of the impermeable membrane is unaffixed and unsealed;
locating a vacuum port at the impermeable membrane;
applying a negative pressure to the vacuum port; and
adjusting the negative pressure to offset air leaks between the impermeable membrane and the object.
