Force Projection onto a Spatial Member Axis
Force elevation, force azimuth, and all three member-axis coordinates participate in both the calculation and the rendered geometry.
Solved spatial projection
Scalar: 117.33 kN
Residual: 0.00e+0

Vector mechanics
Idealization
Right-handed Cartesian axes and SI force units; vector direction and sign are explicit.
Acceptance check
Reconstruct the vector or projection and check the component residual.
