I have an imported cone development. How do I roll it back to cone?
Would the actual part be truly rolled using tapered rollers, or bumped on a brake press?
If the latter, use Sketch Bends, after converting the part to sheet metal.
If the former, it might be easier to re-create the rolled model to suit the flat pattern.
Thank you very much for your reply.
Here is my story. The cone development for a Y-Branch leg has been prepared by a draftsman using trigonometry at Autocad. I have imported dwg file to Solidworks to check weather this development is correct or not. I need to roll that development to cone, however, couldn't manage so far. I have tried Sketch Bend, Flex but got cylindrical bends, not conical.
I have attached the file I am dealing with. I would appreciate a lot if someone could roll that sketch to cone.
Still need to know whether the actual part would be rolled using tapered rollers, or bumped on a brake press?
Bumping on a press would involve a series of sketch bends at incremental angles resulting in a 'flatted' cone.
Tapered rolling would result in a smooth surface and would be more difficult to model from the flat pattern.
Actual part will be rolled using tapered rollers.
..fun challenge,.. I remodeled it in 2012 (and/or exported it cuz I'm NOT a fan of 2016,..pita!)... but, I measured the coords.. came up with some arcs and approx angles.. and tweaked,... it's close, I think? (btw, the units or scale of this seems large.. that is,.. the base dia is about 144".. 12 feet!?)
Thank you for your efforts. Would you please attached the .sldprt file? I would like to understand how you managed it.
Thank you very much.
I personally would do a lofted bend of the finished cone and rather than reverse engineer the part. Take my flat pattern from my lofted bend and check it against the dwg file.
Thank you for your reply. I need to reverse engineer the part. Is there a way?
Wouldn't it be a neat feature if you could just click a face of a part and have it roll into a cone or tube.
Does Inventor not already have this function I believe called 'Contour Roll'.
I am sure this feature has been asked for many times over the years.

I did this a couple ways Ozi... The hard part is figuring out what the taper would be from the flat you had given. I am assuming you already know what this is and the top (with the flat edges) will join or almost join. Whoever laid this out must know. The image on the left (magenta) is a lofted-bend and I used the sketch you supplied to cut it to the exact shape between an unfold and a fold. This way when my loft flattens it matches your flat exactly. The one on the right (green) is a wrap feature which will not flatten. Both are relatively easy to do once you know the taper.
See what you can garner from this.
Thank you very much, much appreciated.
