• convert_drawing_pdf

  Produce a converted copy of a technical-drawing PDF with every recognised value stamped in place (white cover over the original callout, converted text in matching size/rotation) \u2014 dimensions, \xB1 tolerances, fit classes, \xD8/R callouts, threads. The input file is never modified. Without `classifications`, a heuristic converts unambiguous callouts plus (by default) bare numbers as lengths;

• convert_text

  Convert a printed drawing callout (or short text with several callouts) between metric and imperial, preserving notation: "\xD830 H7" \u2192 "\xD81.1811 H7", "84\xB10.1" \u2192 "3.3071\xB10.0039", "R13" \u2192 "R0.5118", "M8" \u2192 "5/16-18 UNC", "1/4-20 UNC" \u2192 "M6". Angles (\xB0) are left unchanged. Set category=surface to read bare numbers as Ra roughness instead of lengths. assume_lengths

• convert_value

  Convert one engineering value between metric and imperial with shop-floor precision rules. Kinds: length (mm\u21C4in), tolerance_deviation (a \xB1 deviation, keeps an extra significant digit), geometric_tolerance (GD&T value), surface_roughness (Ra \xB5m\u21C4\xB5in), weight (kg\u21C4lb), thread (designation lookup, e.g. "M8" \u21C4 "5/16-18 UNC"). Returns the exact value, the display-rounded valu

• extract_drawing_text

  Read the printed text tokens of one page of a technical-drawing PDF: each token with its index, text and position (page points, top-left origin, rotation in degrees), plus page geometry and a heuristic guess of the drawing\u2019s unit system. Use the token indices to build `classifications` for convert_drawing_pdf when you want to decide yourself which tokens are convertible values (e.g. mark a ba

• lookup_thread

  Look up the closest standard counterpart of a thread designation (ISO metric coarse \u21C4 Unified UNC), with major diameters, pitch/TPI and how close the match is. Omit `designation` to get the whole cross-reference chart (M2\u2013M30).
