Dr. Frame 3D
Dr. Software has released , a $900 structural analysis tool that offers direct manipulation and instant feedback for modeling three-dimensional structures. The software was developed to assist architects and engineers make better designs in less time. It is used primarily for frame and truss structures made of metal, concrete or wood. It performs linear and nonlinear analysis; allows interactive manipulation of loads, supports and members; and updates displacements, moments and design checks, all in real time.
