CADSM
3D CAD with Motion Simulation

What is CADSM?
CADSM is a basic 3D CAD with advanced Motion Simulation capabilities. It
is suitable for anyone interested in learning 3D CAD and Motion
Simulation inexpensively before using more sophisticated packages. Its
motion simulation capabilities are comparable to the best and can
provide accurate answers to engineers and scientists in diverse fields.
Educators, students and new engineers will find it ideal for the
teaching and learning of geometry, kinematics, dynamics, vibrations,
mechanisms, linkages, cams, machine design and physics. The program runs
on Windows and Linux PC. Assembly data are unchanged across platforms.

CADSM is a commercial software with a free evaluation period. If you use
this software after the 30-day evaluation period, a fee of US$24 per
user is required for a perpetual license and a one-year subscription to
upgrades and web support. Volume discounts are available.

CADSM allows users to create and manipulate assemblies of parts. The
parts are simple 3D solids, which can be connected by joints,
constraints, contacts, motors, actuators, springs, dampers, forces,
torques or gravity. The parts and connections define the structure,
mechanism or machine of interest. Both open and closed 3D loops are
permitted. CADSM performs full Multibody Dynamics analysis on the
assembly to predict the motion according to Newton's Laws. Animation
using the simulated data produces realistic dynamic behavior of the system.

Users can study the mechanical dynamics in the form of plots and tabular
output. XY plots can be zoomed and set to equal scales. Data series
available include linear and angular displacements, velocities,
accelerations, forces, torques, momenta and kinetic energies.
Acceleration data include transverse, centripetal and Coriollis
accelerations. Users can view forces and torques from joints,
constraints, actuators, springs, dampers, applied forces and inertia.
Data can be exported to spreadsheets or POVRay, a ray-tracing program.
