In US dual dimensioned drawings, what encloses the metric dimension?

In US dual dimensioned drawings, the bracket method is utilized to enclose the metric dimension. This technique is designed to visually distinguish between imperial and metric measurements, especially in contexts where both systems are used simultaneously. By using brackets, the metric dimension is clearly marked, reducing the risk of confusion or misinterpretation during fabrication or construction processes.

The bracket method helps ensure that anyone reading the drawing can easily identify which values correspond to metric measurements as opposed to imperial ones. It supports precise communication of dimensions, which is crucial in welding and manufacturing environments where accuracy is vital.

Understanding the different dimensioning methods, including the bracket method, is essential for effectively interpreting dual dimensioned drawings, which is a common practice in industries that work globally and must navigate both metric and imperial systems.
