Include the product name, drawing number, revision and measurement units. If several sizes are required, give each size its own reference and quantity. This makes later quotation and order discussions easier to track.<\/p><p>Explain whether the drawing describes a new product, a replacement component or a complete cover-and-frame assembly. For replacement work, include photographs showing the existing seating surfaces and the surrounding installation.<\/p><h2 id=\"dimension\">02  Show the Interfaces<\/h2><p>For a manhole cover, include the clear opening, cover dimensions, outside frame dimensions and installation depth. Show the relevant cross sections, seating areas and fixing details. For a drainage grate, show the grate, supporting frame and channel interface separately.<\/p><figure class=\"htbl-article-figure\"><img decoding=\"async\" src=\"https:\/\/huantucast.com\/wp-content\/uploads\/2026\/10\/huantu-blog-frame-dimensions-20261002.webp\" alt=\"Square manhole cover frame beside a dimension drawing and caliper\" loading=\"lazy\"><figcaption>A clear assembly drawing helps distinguish opening dimensions from outside frame size.<\/figcaption><\/figure><p>Mark critical dimensions and tolerances explicitly.
