BFDH model can be used to predict the crystal shape based on gemetrical parameters only. No energy consideration has been made in this model and predicted morphology often doen not correspond to the experimental observations. 

Yes, I agree with Manoj's opinion.  BFDH is a reasonable geometric (reticular) method to foresee the growth shape of crystals (without considering the environmental growth medium). Hartman-Perdok method (published  60 years ago) represents a great improvement that takes into account the energy of deposition of growth units on a pre-existing crystal face. If you are interested in,  I would like to send you a rich literature  and many papers as well (published by my research group on this nice topics).

All the best

Dear Priya,

                          I'm sending you a paper on the subject you are interested in.

All the best

The prediction of the growth morphology is equivalent to the prediction of

growth rates in different crystallographic orientations.

The Bravais-Friedel law reveals the a priori correlation between the morphological importance (MI) of a crystal face and its interplanar distance dhkl. The MI of a crystal face is commonly understood as its relative size in a given crystal habit.

According to the Bravais-Friedel law, the observed crystal faces are those

with the largest interplanar distances. The larger the interplanar distance, the more important the corresponding crystal face. This law is violated sometimes; therefore, Donnay and Harker extended it by considering

the screw axis and the glide planes. In this way, the Bravais-Friedel-Donnay-Harker law (BFDH law) was introduced. This law often gives a satisfactory

description of crystal morphologies.

Bravais Friedel Donnay Harker (BFDH) analysis was carried out in order to estimate the faces that are supposed to appear in the crystals morphology. This analysis considers the effect of symmetry operations on the interplanar distances of crystal faces.
