Each sheet prints a part table (P/N and DESCRIPTION) and nominal drawing dimensions; the sheets say "ALL DIMENSIONS ARE NOMINAL" and "DRAWING NOT TO SCALE". Drawing dimensions are not recorded as product dimensions because the extracted text does not tie each figure to a labeled axis. No weights or prices are read from it.
