See pictures of paper tube that I bent to look like the sheet metal part I need to model.
How in the world would I draw this?
Thanks, Jerry

Hi Gerald,
I was going to have a crack at this as a normal model but you want sheet metal which is something I haven't really dabbled with yet. But I'm interested to see the outcome nonetheless. How much smaller is the bottom OD to the top OD? In fact, have you got any approx. dimensions to go on at this stage?

Gerald,, I had a heck of a time with this.. Thanks for that.... I thought I could use the indent feature and was successful to a point but when I would try to slice off a portion my 2016 would crash. The indent feature is still in my model but suppressed if you want to take a look. Thought about using a form tool but if I remember correctly it does not work on bends. Ended up modeling this using surfaces with a guesstimate on how much the top edge of the tube would suck in. There are two configurations. One for the SM cylinder and another for the caved. The SM cylinder can be flattened. Perhaps you can get some ideas from this. I'm quite certain that you cannot model this from sheet metal entirely.
To use the form tool you need a flat surface, you might could use it first then bend it.
I couldn't tell whether it was a cylinder or a cone.
I experimented a bit, but quickly gave up.
Maybe that is a mis-representation on my part as Gerry's thread describes it as a 'tube' but the JPG's certainly look like they are tapered (cones) to me (Optical illusion perhaps).
Dave.
Bravo Dennis. The shape is right but I can't flatten it. I need to be able to give the cutter a flat.
I see on the Indent Overview that, "Either the target body or the tool body must be a solid body." I made a solid indent tool and after a little trial and error was able to make it work. However, positioning the tool is proving quite difficult... and when I try to trim the part SW crashes.
Went a round with Hawkridge they told me SW can't put a bend on a bend, only simple straight line press brake stuff.
Bother.
Thanks for looking
Gerald,,, You are starting with a cylinder then caving in the end.. Correct?. Then the cylinder flat pattern is what you want. The cylinder does flatten. Were you able to open my file? If so make the Default configuration active and then use the sheet metal flatten tool. This will give you a flat pattern. Even if you used the indent, that has to be suppressed prior to making the flat pattern. Thus the configurations to take care of that for you.
OK, yes, it will flatten but just gives me an empty view, dashed outline. What causes that?
Did you make the default configuration active?
Edit:... What I did Gerald is made the thicken1 hidden in the default config, so if you try to flatten from the Caved config you will not see the flat pattern. Make sense? If you flatten from the default config everything is groovy.
