VTK Import for Inventor is a Visualization Toolkit (.vtk) file import add-in for Inventor. This add-in gives Inventor the ability to import polygon data from VTK files. VTK Import for Inventor reads polygon mesh data stored in VTK files and imports it into Inventor. A polygon mesh in a VTK file is comprised of a set of triangular faces. VTK Import for Inventor creates trimmed planar surfaces for each triangle and knits them together to create a body. If the polygon mesh is closed (i.e. it does not contain boundary edges) then VTK Import for Inventor will create a closed body feature, otherwise an open surface will be created. VTK Import for Inventor is very easy to use. Once installed, it must be loaded into the Inventor environment. There are simple instructions for this in the ReadMe file. Once loaded, it also adds a ribbon bar to the Inventor user interface called "Add-Ins" containing the new commands.
