It is written for engineers, designers and metrology technicians to align drawing interpretation with measurement aims. Designers gain clearer understanding of how measurement requirements connect to drawing information such as size, position, shape and surface texture. Metrology technicians learn how to interpret those aims to support consistent measurement outcomes and effective communication across design and measurement.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/measurement-good-practice-guide-no-79-fundamental-good-practice-in-the-design-and-interpretation-of-engineering-drawings-for-measurement-processes/650421/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/measurement-good-practice-guide-no-79-fundamental-good-practice-in-the-design-and-interpretation-of-engineering-drawings-for-measurement-processes/650421.png","ImageObject",300,407,{"name":92,"@type":93},"OKfine","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-24",true,{"@type":102,"interactionType":103,"userInteractionCount":81},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"Who is this guide intended for?","Question",{"text":112,"@type":113},"The guide is written for engineers, designers, and metrology technicians.
