MoI’s sleek intuitive UI blends a fluid easy workflow with powerful tools, making it the perfect choice for someone who has been frustrated with the complexity of existing CAD tools.
MoI is also a fantastic complementary tool for a polygon-based artist since its CAD toolset and advanced boolean functions enable extremely rapid creation of mechanical or man-made type “hard surface” models. The icing on the cake is MoI’s unique polygon mesh export that generates exceptionally clean and crisp N-Gon polygon meshes from CAD NURBS models.
