summary Preservationists have an impressive array of digital tools to aid them in documentation and analysis of historic structures. The tools range from near photo-realistic renderings to demonstrate what a “restored” building might have looked like at one specifi c time in history to complex chemical analysis of paint chips and pigments to geographic information systems used as management tools for historic prop er ties. Computer-aided design / computer-aided manufacturing (CAD/CAM) is set of important digital aids in historic preservation efforts. This paper presents a case study of the use of CAD/CAM in support of an effort to restore a textile block house designed by Frank Lloyd Wright. CAD/CAM methods are being employed to help produce a new mold so that new textile blocks can be manufactured that match the existing blocks. An existing textile block mold was digitally scanned, digitally mirrored and edited, and will be fabricated from an aluminum billet to replace a mold that no longer exists. Although seemingly a simple process and well within current technological abilities, the work proved substantially more challenging that initially imagined.
