I use the Edge Surface component for generating a surface from three arcs. The result is unfortunately a Brep which has 7 surfaces but only 4 faces. This does not happen if I bake the arcs and generate the surface directly in Rhino.
Surfaces with surface index 3-6 correspond to the brep faces. Surface 0 is the whole surface with C0-continuities. Surface 1&2 are parts of it (see image). So there are kind of 3 valid results but only one is used for the brep.
Is there a fast way to recognize such results without checking for every surface if its index is related to a face?
