Dear Christophe, Thank you very much for your answer. The idea of displaying the number of lines or surfaces is what I thought I was doing in my example when I wrote:
surfaces()=Surface "*"; Printf("Original Surfaces: ",surfaces()); lines()=Line "*"; Printf("Original Lines:", lines()); after merging the IGS file. At this point, I can't see any duplicated entities (the number is correct), but I don't know if this is what you mean by displaying the curve or surface tags.
