I also came across some strange things. Anyone could give me any suggestions?

I am using incremental_builder and it works fluently at most of the time.
However, when I play with a real CAD model, it failed in begin_facet(). The
output debug information is:
...
add_vertex_to_facet(): input error: disconnected facet complexes at vertex
69: involved facets are : 112 81 80 79 (closed cycle) and.

It should be noted that before starting a new face, I did test_facet first
and it passed the test procedure. How could that happen?

Thanks and have a nice weekend.
