Hello
I try to create a complex surface/volume using a combination of sweep rails and curve network commands but can’t get a result! I used the curves shown in the attached file as profile or as curves network (for the rounded part). Can anyone tell me how to proceed ? What would be the best way to do it?
Best regards and thank you!

Hi Richard - You can get something if you split up the curves a little differently. Not sure it is what you want- the curves are pretty convoluted.

Hello Pascal
Thanks a lot for your answer. That’s what I was looking for. I can always modify the surface… Did you use both sweep rail and curves network? So you worked around using segment by segment?
Thanks again
Richard
Hi Richard- these are all Network surfaces - I chose that because the curves are ‘all kinds’ and NetworkSrf is very tolerant of mismatched curves.
-Pascal
Ok! All kinds? Meaning open and closed curves?
No, I mean simple ‘clean’ ones and very dense ones - curves that do not match one another well in structure. Some surfacing commands much prefer matched curves - Loft, EdgeSrf, Sweep2 (Cross sections) and some do not care so much - NetworkSrf, PlanarSrf, Patch, for example.
-Pascal
Ok. I see. Thanks a lot for your help Pascal!

Richard
By the way is there a simple way to make all those curves match perfectly?
Well the simple way out is to Rebuild curves to the same degree and point count - but to be honest in this case, I would not worry too much since Network seems to manage OK with them as they are. Note some commands have Rebuild built into the process as an option - if selected the input curves are rebuilt to the point count the user chooses and degree 3 before a surface is made from them. Rebuilding always modifies the curve shape - a little or a lot, depending.
-Pascal
Ok, I’ll keep that in mind for the next time! Thanks again!

Richard
