hallo everyone, what should i do when a infection point occurs in my cv line in order to achieve the shape i want, should i cut it into two pieces ?
You can use the Object Edit > Detach (under Attach) tool to split your curve into 2 connected curves.
OR In case you want to use your original curve (with the inflection) as a reference, you could simply 'Template' it and then create 2 new connected curves with the same shape/flow.
Most people avoid working with curves that have inflections because it affects the surfaces. But if you're only creating a concept model, you could take this liberty. Alternatively, if this isn't a major surface, you can still work with an inflected curve.
