Dimension Lines In Engineering Drawing
Dimension Lines In Engineering Drawing - Web dimension and extension lines (figure 2.1. Extension lines are used to indicate the boundaries of a feature to which a dimension is applied. The mechanical engineering branch, mechanical systems division, has been delegated Dimension notesall dimensions apply after surface treatment. Web the dimension line has two arrowheads between the extension lines and the measurement on top (or inside, like in the image above) the line.
It is indicated by arrowheads, it is drawn parallel to the surface whose length must be indicated. Web the gsfc engineering drawing standards manual is the official source for the requirements and interpretations to be used in the development and presentation of engineering drawings and related documentation for the gsfc. Engineering drawings and sketches need to display simplicity and uniformity, and. Identify line types used in technical drawings interpret dimensioning on technical drawings use professional lettering techniques Extension line — a thin, solid line perpendicular to a dimension line, indicating which feature is associated with the dimension. Meet the design requirements and ensure the service performance of components; Web the dimension line has two arrowheads between the extension lines and the measurement on top (or inside, like in the image above) the line.
