Advantages of the Boundary Representation is following:

    I.  This format provides efficient picture generation and easy access to other geometric information.

    II.  The changes generated by most editing operations (for example tilting one face through a given angle) cause local effects not global ones.

    III. It is relatively easy to define a face lying on a surface described parametrically.

    IV.  It is easy to create objects by "sweeping", that means a complex two-dimensional profile can be translated or rotated around an axis to give a shape in three-dimensions.

     V. The major advantage of b-rep is that it is extremely appropriate to construct solid models of unusual shapes that are hard to build by using primitives, for example aircraft fuselage and automobile body styling. This is also comparatively simple to convert a b-rep model into a wire-frame model.
