What does the bend tangent line indicate?

The bend tangent line is crucial in the context of bending materials, particularly in sheet metal fabrication and structural mechanics. It indicates the points where the bend begins and ends. This line is essential for accurately determining the geometry of the bend, ensuring that the final shape meets design specifications.

The importance of the bend tangent line lies in its role in the overall fabrication process. When a bend is made in a material, it affects the overall dimensions of the piece. Knowing where the bend starts and finishes helps in calculating the bend allowances and ensures proper fits and finishes in assemblies.

Understanding the precise location of the bend tangent line aids in maintaining structural integrity and adherence to design parameters. It's a foundational aspect of creating accurate bends, which are critical for the performance and aesthetics of the final product.
