OBJ Import for SpaceClaim is a Wavefront (.obj) file import add-in for SpaceClaim®. This add-in gives SpaceClaim the ability to import polygon mesh data from Wavefront OBJ files. OBJ Import for SpaceClaim reads polygon mesh data stored in OBJ files and imports it into SpaceClaim. A polygon mesh in an OBJ file is comprised of a set of triangular or quad faces. OBJ Import for SpaceClaim creates trimmed planar surfaces for each face and knits them together to create a solid. The solid is then cleaned up so that adjacent coplanar faces are merged in single trimmed planar faces. If the polygon mesh is closed (i.e. it does not contain boundary edges) then OBJ Import for SpaceClaim will create a closed solid feature, otherwise an open surface will be created. OBJ Import for SpaceClaim is very easy to use. It adds new commands to SpaceClaim. Once installed, it automatically loads itself into SpaceClaim and adds a new ribbon bar to SpaceClaim called "SYCODE" containing the newly added commands. The 'SYCODE' ribbon bar consists of the following commands: Import - Import a OBJ file. Help - Display the OBJ Import for SpaceClaim help file. Register - Register your copy of OBJ Import for SpaceClaim. About - Display the OBJ Import for SpaceClaim 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.
