kinglevel Posted September 27, 2010 Posted September 27, 2010 Hi Long time since i was here, my progress with inventor is awesome.. thanks to you all! Now, ive ben able to solve lots of problems of my own.. but i dont really know how to do this one. Well i call it an "orange wedge" couse we use that in sweden to describe the shape. How to loft it and unfold it? Take a look at the attachments. cheers Part1.zip Quote
rdharvey Posted September 27, 2010 Posted September 27, 2010 what are you trying to do with the sketch? Quote
kinglevel Posted September 27, 2010 Author Posted September 27, 2010 what are you trying to do with the sketch? something like an orange wedge http://www.clipartguide.com/_small/0808-0809-1213-0551.jpg Quote
kinglevel Posted September 27, 2010 Author Posted September 27, 2010 hah orange wedge peel yes.. at least thats the shape i want to unfold Quote
Tiger Posted September 27, 2010 Posted September 27, 2010 now I don't know Inventor but perhaps you are thinking of this from the wrong angle. You need some sort of thickness to the peel, even if just very thin, so can't you take on of the peel-lines and offset it inwards (towards the center of the orange), close the sketch and use Revolve? Then flat-pattern it? Quote
kinglevel Posted September 27, 2010 Author Posted September 27, 2010 hmm.. i think thats not possible, the back of it cannot be "round" to be unfolded in inventor i think. it needs only 1 radius. Quote
Tiger Posted September 27, 2010 Posted September 27, 2010 ok, next idea. Why do you need it unfolded? Can it be solved with good old fashioned math? Quote
kinglevel Posted September 27, 2010 Author Posted September 27, 2010 well.. yeah thats also possible. The main idea was to do a fin for a boat. But we have now solved it by taking two sheets and spot weld it. more by hand and less accurate. as you see on the image, it would be great to know how to fold it togheter for more accuracy. Quote
kinglevel Posted September 27, 2010 Author Posted September 27, 2010 this is not as the first problem, but i tried to find a ordinary solution to use at this problem Quote
shift1313 Posted September 27, 2010 Posted September 27, 2010 Just as a starting point i probably would revolve this shape and not loft it. Since it did come from a sphere. As far as flattening in im not sure off the top of my head. Its a piece that would need to be formed and not just bent so im not sure if/how you can flatten that. Quote
dshowalt Posted September 28, 2010 Posted September 28, 2010 Looks like a revolved object would work for an oragne peel Quote
