This is a NASA Goddard sample assembly drawing. Extract title-block identifiers and every row of the 'List of Material' table on the right side of the sheet. Each table row has an item number, quantity, part number, description, and material. Read item numbers exactly as printed (they run from 1 at the bottom upward). The top row of the table is the overall assembly (e.g. 'MOUNT C ASSEMBLY') and may not have a quantity. Material is often 'CRES' (corrosion-resistant steel) for fasteners; leave material blank if not printed for a row. Ignore the prose paragraph below the figure and the general tolerance/notes block. If the title block, drawing-number, or revision boxes are blank (this is a sample/template sheet), return null for drawingTitle/drawingNumber/revision rather than inferring them from the page footer or the List of Material.
