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

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

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

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

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