Leave a small gap in the middle of the part’s length and draw the break lines. This indicates that the middle section is omitted. 3. Add Dimensions

For a long part with a constant cross-section (like a shaft or pipe), you should not draw the entire length to scale. Instead, use (линии разрыва). These are typically thin, wavy lines or "Z" shaped zigzag lines drawn by hand or with a ruler, depending on the specific standard (GOST) requirement in your workbook. 2. Prepare the Views

Sketch the specific features at both ends of the part (e.g., chamfers, holes, or threads).

Even with a break, use a standard scale (e.g., 1:1 or 1:2) for the ends of the part.

Place a single dimension line across the entire part, including the break.

) before the dimension. If the cross-section is not immediately clear from the front view, you may need to draw a (вынесенное сечение) or a superimposed section (наложенное сечение) to show the shape (e.g., a square or hexagon).

To complete the task for a "long piece" in the , you must use break lines to shorten the visual representation while writing the actual total length on the dimension line. Ensure you include the necessary diameter symbols and any required cross-sectional views to fully define the part's geometry.
