 Bonjour, Comment peut-on obtenir une surface homogène à partir du contour et des deux courbes au dessus sans coupure. Merci d' advances Osx59 Hello, How can one obtain a homogeneous surface starting from contour and of the two curves to the top without cut. thank you Osx59 EDITED: 3 Feb 2010 by OSX59 Attachments: Image Attachments:

 Hi Osx59, I had to break down the curves and used two surfacing techniques. Please see the attached JPEG and 3dm model. Hope this helps. Michael T. Michael Tuttle a.k.a. mictu http://www.coroflot.com/fish317537 EDITED: 4 Nov 2010 by MICTU_UTCIM

 Merci pour votre aide. J'avais tout essayé, sauf votre solution. je vais la refaire depuis le début. Encore merci et a bientôt Thank you for your assistance. J' had very tested, except your solution. I will remake it since the beginning. Still thank you and has soon

 3290.7 In reply to 3290.6 Hi Vincent, looks like a good result! One note - if you have 2 profile curves arranged like so (one oriented towards the Top view and the other oriented from a side view): Where at least one of them is closed, then it is actually possible to generate a surface directly from those curves by using Construct > Boolean > Isect. Start by selecting one of the curves like this: Then run the boolean intersection command, and select the other curve, then right-click or push the "Done" button and it will generate this surface result: Then you can extrude or shell that surface to thicken it into a solid. This way you can skip some steps, like you do not have to use a network surface if you have those 2 side profiles in place. It's also the equivalent of extruding the curves into surfaces first and then using boolean intersection or trimming between the extruded pieces - the boolean commands have an automatic extrusion mechanism in them to do extrusions like that for you with less steps. One other note with this method - it can be good to have the side profile kind of extended slightly so that it sticks out a bit to either side of the other closed profile. - Michael EDITED: 3 Feb 2010 by MICHAEL GIBSON

 3290.8 In reply to 3290.7 I love this command! Still the need to get it in my head, but so very cool!

 3290.9 In reply to 3290.8 Hi Burr, > I love this command! Still the need to get it in my > head, but so very cool! Maybe it will make a bit more sense if I show the internal intermediate stage. So with the 2 input curves like this: The booleans will internally create extrusions for those, the closed curve becomes a volume and the open curve becomes a surface, like this: Then "intersection" means to take the parts that are common to both objects. For a volume and a surface it will take the parts of the surface that are also contained within the volume, which gives this result: But it's kind of nice to be able to generate this result just directly from the curves and let the booleans internally deal with extrusions of pieces into surfaces or volumes instead of having to do those as additional manual steps. - Michael
