  The LHC Higgs data is showing a gradual inclination towards the SM result and
realization of an SM-like limit becomes essential for BSM scenarios to survive.
Considering the accuracy that can be achieved in future colliders, BSMs that
acquire the alignment limit with an SM-like Higgs boson coupling can surpass
others in the long run. Using a convenient parametrization, we demonstrate that
the alignment limit for CP-conserving 3HDMs takes on the same analytic
structure as that in the case of 2HDMs. Using the example of a $Z_3$-symmetric
3HDM, we illustrate how such alignment conditions can be efficiently
implemented for numerical analysis in a realistic scenario.
