We present photo-ionization and morpho-kinematic analyses of the ejecta of novae. The sample consists of ten novae belonging to the Fe II, He/N and hybrid classes. The Fe II class of novae in the sample have bipolar cone-like structures, with or without equatorial rings with inclination angle in the range of 40°–60°. The He/N novae have bullet-nose curve along with bipolar cone-like structures and equatorial rings with an inclination angle of ~80°. The hybrid nova in the sample is a bipolar frustum of prolate spheroid along with bipolar cone-like structures and equatorial rings with an inclination angle of 63°.
