Technical drawing is a very important tool for communication between people that deal with the same professions. In mechanical engineering, technical drawings are used to show dimensions and tolerances of parts, to show assemblies, and production and manufacturing techniques of parts and part surfaces.
To obtain a successful technical drawing in mechanics, you need to know the general standards and rules. These rules are generally defined by ISO or ASME.
Showing ribs of mechanical parts in technical drawings is a very important quality indicator of the drawer. Let’s check how to show ribs in mechanical technical drawings.

Showing Ribs In Technical Drawing Section Views
When section lining of a part is performed in technical drawing, thin sections such as webs, ribs, or gear teeth are not sectioned with a hatch pattern. If the section plane goes through these thin sections, do not use a hatch pattern to show that thin section. This is because, if you show these thin sections as section hatch, false thickness perception can occur at the reader of the technical drawing. A reader can understand, there is a thin, supportive section in that part.
If the cutting plane goes through the crosswise of the thin section, you must show it with a hatch pattern. Because the thickness of the rib or the web is the same as the whole part in that view.
Sometimes, it can not be easily understood that there is a space or supportive thin section in section views where the hatch is not used. In this case, the technical drawing creator can use double-spaced hatch patterns to show that thin section to readers.
Showing the thin sections such as ribs in technical drawings are very simple like this.
