Intel Dual Core processor or later. With the streamlined controls of synchronous modeling, creative design and intuitive handling of imported 3D data is promoted. This is typically called "history" or "regeneration based" modeling. Each subsequent feature is built on the previous feature. This would be compatible with both 32 bit and 64 bit windows. Parametric relationships can be applied directly to the solid features without having to depend on 2D sketch geometry, and common parametric relationships are applied automatically. You can easily remove artifacts and patch areas in the mesh as well as repair portions of the mesh.
