Abstract A method for construction of space‐filling models of proteins of improved accuracy was developed from the dihedral angle technique proposed by Hauschka and Segal (P. V. Hauschka and D. M. Segal, Biopolymers , 4 , 1051, 1966). Tools were designed to facilitate the marking of accurate reference lines on component atoms and a simple method for cementing the fixed angles was devised. The torsion angle method was extended to include all side chains. The improved technique was used to assemble a model of sperm whale metmyoglobin from the x‐ray data.
