To layout walls orthogonally in a wing angled at 18 degrees, what should the CAD designer do?

1. Create and save a custom UCS for the angled wing

2. Rotate the entire drawing

3. Use the Mirror command

4. Draw using construction lines

The correct answer is: Create and save a custom UCS for the angled wing

Creating and saving a custom User Coordinate System (UCS) for the angled wing is the most effective approach when laying out walls orthogonally in this scenario. By defining a UCS that aligns with the wing’s angle of 18 degrees, the designer can establish a new reference plane that makes it easier to draw objects relative to this specific orientation. This simplifies the process of ensuring that walls are straight and aligned properly within the context of the angled geometry. Using a custom UCS allows for accurate placement and alignment of elements, as it enables the designer to work within a coordinate system that matches the design requirements. When the UCS is aligned with the angled wing, orthogonal objects can be drawn in relation to this new reference, making the drafting process more intuitive and reducing potential errors that might arise from trying to adjust angles manually. While rotating the entire drawing could align the design with the desired angle, this method would complicate the entire drawing and may disrupt the orientation of other elements. The Mirror command is used for duplicating objects symmetrically and does not facilitate orthogonal layout in an angled space. Drawing with construction lines could provide a temporary reference but lacks the precision and efficiency that a custom UCS offers. Hence, setting up a custom UCS is the most practical
