OBJ Import for Inventor is a Wavefront OBJ file import add-in for Inventor®. This add-in gives Inventor the ability to import polygon data from OBJ files.
OBJ Import for Inventor reads polygon mesh data stored in OBJ files and imports it into Inventor. A polygon mesh in an OBJ file is comprised of a set of triangular and/or quad faces. OBJ Import for Inventor creates trimmed planar surfaces for each triangle/quad and knits them together to create a body. If the polygon mesh is closed (i.e. it does not contain boundary edges) then OBJ Import for Inventor will create a closed body feature, otherwise an open surface will be created.
OBJ Import for Inventor is very easy to use. Once installed, it automatically loads itself into Inventor and adds a new submenu called "OBJImport" to the Inventor menu.
The 'OBJImport' submenu consists of the following commands:
Import - Imports an OBJ file
Help - Displays the OBJ Import for Inventor help file
Register - Registers your copy of OBJ Import for Inventor
About - Displays the OBJ Import for Inventor About box
The OBJ File Format
The OBJ file format is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package. The file format is open and has been adopted by other 3D graphics application vendors, making it a universally accepted geometry file format. The OBJ file format is a simple data format that represents 3D geometry alone - namely, the position of each vertex, the texture coordinate associated with a vertex, the normal at each vertex, and the faces that make each polygon.
