How can I make a shet metal part as one piece that will unfold? One end circular the other end a hexagon.
If you suppress the cut and the boss, your part will flatten. The cut makes the end faces not normal to the main face of the sheet metal. SW can only flatten parts that follow the rules.
You can't add a flange to a sheet metal loft, but if all you need is a flat pattern, you can make them separate bodies, then save as DXF and combine them afterward.
Start by creating the bottom piece as a Base Flange, rather than a regular Solid Extrude. Now you can add an Edge Flange, adjusting the values until it closely matches the profile of the loft.
Using the face of the Edge Flange as a sketch plane, convert the edges of the flange and make an extruded cut through the Lofted body.
Save the two flat patterns as DXF files, then combine them together. You should be able to align the tab on the hex piece with the cutout on the lofted piece, giving you a pretty decent representation of the total flat pattern.
Thats one way.
Matt's is much simpler, check it out.
Definately, I found that as well. I just thought you wanted a flat pattern of both pieces together, not just the lofted piece.
