Aik-Siong Koh from AR-CAD informs me that his company has released a motion and dynamic simulation add-in for Autodesk Inventor 2009 called IN-Motion and it is priced at only $200. According to the press release:
IN-Motion is a fully integrated Autodesk Inventor software addin that performs the force and torque calculations of moving Autodesk Inventor assemblies with very little extra effort from the user. All the assembly constraint information from Autodesk Inventor is automatically reused in the dynamics simulation. Only a few user-specified input of motions, forces, torques and/or gravity are needed to run realistic simulations. Forces and torques experienced at joints, motors and actuators can be plotted or exported in spreadsheet format for further study.
All this for just $200 as opposed to “many thousands for competing products“. And speaking about price, this is precisely the same stuff that powers Alibre Motion, the motion simulation add-on for Alibre Design. Feel free to download a 30 day trial of IN-Motion here.
