Question

In a 3D Wedge-Dash projection, if the lowest priority substituent (Group 4) is incorrectly located on the solid wedge (pointing directly at the observer), what immediate mathematical adjustment must be made after tracing the $1 \rightarrow 2 \rightarrow 3$ path?

Prashant Kotian · Accepted Answer

Correct answer: B. If Group 4 is on a solid wedge, it is pointing toward the viewer, violating the standard viewing perspective. The shortcut dictates tracing the path as it appears, and then strictly reversing the final result. An apparent anti-clockwise (S) trace means the actual configuration is 'R'.
