Conversion from Inventor to Nastran is not supported yet :(

Autodesk Inventor is a CAD application for 3D mechanical design, simulation, visualization and documentation. It is built on ShapeManager, geometric modeling kernel by Autodesk.

Inventor enables 2D and 3D data integration in a single environment, virtually representing the final product. It allows users to check the form, fit, and functions of the product before it is built. The application provides strong parametric, direct edit and freeform modeling tools as well as multi-CAD translation abilities.

MSC Nastran is a multidisciplinary structural analysis application used by engineers to perform static, dynamic, and thermal analysis across the linear and nonlinear domains, complemented with automated structural optimization and award winning embedded fatigue analysis technologies, all enabled by high performance computing.

Engineers use MSC Nastran to ensure structural systems have the necessary strength, stiffness, and life to preclude failure (excess stresses, resonance, buckling, or detrimental deformations) that may compromise structural function and safety. MSC Nastran is also used to improve the economy and passenger comfort of structural designs
