I’m going to model a comb. I seperated it into two parts. The handle and the head. The head part includes spikes which are placed at top. I have problem with head’s lower part. I created some guiding curves in order to use network surface command but I failed.
Please help me to find out what the problem is.

you have to join the curves back together partially, dont quater them. just see the attached file how they should look before you can use NetworkSrf

Hi Alex - here’s another way to do this, just for the sake of variety.

Thank you Pascal
Thank you RichardZ.
Unfortunately it keeps failing.
I tried to complete my comb model but I still have tangency issue. I tried out some ways but I couldn’t make any progress. Help!!!
I have hidden my curves in the following file.

I have surface continuity issue. Please look at my last uploaded file.
hi jim looks good, but maybe also explain what you did, i assume you used blend edge?
i made now only one step replacing this cramped surface in the middle. to get there you have to rebuild the two surfaces which i replaced with the purple surface in my file to one surface to get a matchable edge. then use edge surface, rebuild it to a lower number something like 5/5 by degree 3 and use MatchSrf with the option Multiple Matches.
to make this hair brush really well tangential to each surface you should start completely different, not using curves which are actually not tangential to each surface.

You should be able to tell how each surface was made by looking at its structure. The picture below shows the 3 types of surfaces used. The magenta curves were used for trimming to make way for the Sweep2 and BlendSrf surfaces
somebody experienced yes, but somebody trying to learn probably not
Understanding the structure of the different types of surfaces is something that is worthy of trying to learn as soon as possible. That undemanding will make learning other things in Rhino a lot easier.
i agree and thats what people come here for either. i at least learned most of the fancy from the discourse.
can you please explain how you kept your surfaces so simple (clean). When I take your file and network the large surface, for example, I have loads of isocurves?
hi Et, i am not sure what you are seeing, maybe because i have the isocurves set to 0 and off on that surface. if i set to 1 i get this.
you can undensify it further using the option Loose while also increasing the edge curve tolerance but playing too much may lead to unjoinable edges so there is a limit of course.
