You can create fillets and chamfers with constant radii on edges on 3D solids and surfaces. The Fillet and Chamfer operations do not need much introduction they do exactly what we expect them to do - now in 3D. The loft shape is controlled by guide curves and a setting that keeps the loft direction perpendicular to the profile faces.

The highlighted regions of this bracket geometry are generated using the loft command by joining the two cross-sectional faces. To further control the shape of the loft, you can include guide curves that connect the profiles. For start and end profiles, you can specify the direction of the loft in relation to the profile or adjacent faces. You can create solid or surface objects from cross sections defined by a face or a profile curve. The Loft operation comes in handy when Extrude or Sweep won’t do the job because they do not support multiple cross sections. Let’s take a look in more detail at what you can do with these new features.

This optional add-on also includes interoperability tools for the import and export of CAD designs. Have you been interested in learning how to create fillets on 3D designs or how to generate shell approximations of imported geometric objects? The latest version of the COMSOL Multiphysics® software includes the new Design Module, which provides these and other tools for easier and more advanced geometric modeling.
