Flat Pattern not Working

Anonymous — Mon, 17 Jun 2019 12:38:24 GMT

I designed a tube like which in the first picture

and I try to create a flat pattern from part of it but it's doesn't work and the fusion 360 show me the same part like in the second picture

any ideas to solve this problem?

Sketches are not constrained.

Thickness is not needed in sketches.

No Bends?

Not following the 4 sheet metal rules?

Thank you for a replay

there are no bends and i don't know what exactly the 4 rules or what exactly write correct rules.

can you show me the solution in the fusion 360, please?

Um, your file does not contain any sheet metal bodies. Nor does it contain any regular bodies that conform to sheet metal rules. The flat pattern feature in F360 only works on sheet metal bodies. If you want to build something resembling your tapered tube, and get a flat pattern of it out of F360, you're going to have to learn to work within the sheet metal workspace.

Also, why did you split body the tube into a bunch of separate bodies?

Maybe the Attached will give you some ideas.

Sheet metal must be uniform thickness.

Sheet metal must have bends.

Bends must be cylindrical or conical.

Cuts must be perpendicular to the flat.

I would assume these are for welds, but I think I would Split such a way that there would be lapped joints rather than butt joints for a bit of extra strength.
