gargoyle27 Posted April 1, 2011 Share Posted April 1, 2011 (edited) we are making a cone made from a flat peice of plate that will be rolled into a cone, can i use inventor to figure out what the flat shape will be? the cone is 3.5" tall, the small diameter is 13" and the large is 27" thanks Edited April 1, 2011 by gargoyle27 Quote Link to comment Share on other sites More sharing options...
Steve_wright Posted April 1, 2011 Share Posted April 1, 2011 here i go again..lol please bare with me but this is what i would do draw your first circle 13" finish sketch you need to offset a plane 3.5" from xy plane then draw your other circle on this plane loft the 2 together..thickien the cone to what ever thickness your material is then extrude a line at one side of the cone only then split the cone with the extruded line then convert to sheet metal set your defaults then flatten it worked for me ..and once again i am hoping this is what you are looking for... my apologies if it isn't..(the measurements have been converted to millimetres ) Quote Link to comment Share on other sites More sharing options...
gargoyle27 Posted April 1, 2011 Author Share Posted April 1, 2011 hmmm, interesting, i'm not sure that's what i'm looking for, i was able to find an online calculator for this, i knew one would exist but wanted to use inventor if possible (calculator i found is here http://www.red-bag.com/engintools/calccone.php) that is more what i was looking for, so it can be burnt out on our burn table and bend into a cone, as it turn out its expanded metal so it will be done by hand thanks anyway tho Quote Link to comment Share on other sites More sharing options...

JD Mather Posted April 1, 2011 Share Posted April 1, 2011 Are you really stuck back on Inventor 2009 (solution depends on using 2010 or latter or 2009 or earlier)? 2009 a revolved angle line as surface - then Thicken. I post solution when I get a chance. Quote Link to comment Share on other sites More sharing options...
gargoyle27 Posted April 1, 2011 Author Share Posted April 1, 2011 yeah 2009, we were looking at upgrading, but it's pricey, if we would have known we would have just held the subscription because thats about how much upgrading now would cost Quote Link to comment Share on other sites More sharing options...
kencaz Posted April 2, 2011 Share Posted April 2, 2011 As JD stated above... Revolve a surface, (359.9) angle. Thicken, convert to sheet metal, (check your default thickness), and change accordingly. Now you should be able to yield your flat pattern from your cone. Now you can export surface to .dxf for cutting... Good Luck KC Quote Link to comment Share on other sites More sharing options...
JD Mather Posted April 2, 2011 Share Posted April 2, 2011 You modeled with radius rather than the problem description of diameter, but yes. Quote Link to comment Share on other sites More sharing options...
gargoyle27 Posted April 4, 2011 Author Share Posted April 4, 2011 i'm unfamiliar with sheet metal, how do i get it to flaten? thats as far as i've gotten Quote Link to comment Share on other sites More sharing options...
JD Mather Posted April 4, 2011 Share Posted April 4, 2011 Go to the sheet metal environment. Make sure your Sheet Metal styles are set to thickness of material. Click on a face of the part and select Flat Pattern. Quote Link to comment Share on other sites More sharing options...
gargoyle27 Posted April 4, 2011 Author Share Posted April 4, 2011 ok i got it figured out, thanks guys! Quote Link to comment Share on other sites More sharing options...
