How are dimensions shown on aircraft drawings?

Dimensions on aircraft drawings are shown using dimension lines that are typically solid. Dimension lines provide the necessary information for measurements and are clearly marked to indicate the lengths and sizes of various components on the drawing. This clarity is crucial for maintenance, manufacturing, or inspection processes in aviation, where precision is essential.

The standard practice is to have these solid lines with associated measurement markings placed between them, indicating the exact dimensions required for the parts or assemblies depicted. This approach ensures that anyone interpreting the drawings can easily understand the specifications without confusion.

In contrast, other options do not accurately represent how dimensions are typically conveyed in technical drawings. For instance, using dotted lines is not a standard method for conveying dimensions, as it might lead to ambiguity. Dimensional information is also not confined to the title block or revision block, as incorporating it into the main body of the drawing ensures that it is immediately visible and relevant to the specific components being depicted.
