Modeling FoamBoard Fuselage

I thought this would be simple, but I am not having luck.

I made a simple fuselage from a top and side view drawing of an airplane.

My end goal is to have a flat pattern of the top, bottom, left, right, and rear faces of this to trace onto 0.2" thick foam-board.

The closest way I can think of doing this now is using the offset surface command to put each face into a new part, giving it thickness, and adding a "flat" configuration to put into a drawing and print out to use for tracing/cutting.

However, this method does not allow for overlap correction ( which pair of faces is on the outside, or sandwiched inside) as easily as say the sheet metal tool does in solidworks.

Any ideas? I know there is a guru out there than can convert this thing into 5 pieces in a jiffy with flat pattern availability.

Is there a way to do this without altering the way my part was originally drawn?

Any help much appreciated!

Hi Eric,

I might be wrong, but what I have done is choose the face you wanted convert to a flat pattern and face delete the rest. Use the surface flatten and thicken to get the flat pattern of that surface. Let me know what you think.

Thanks,

Thanks for taking the time to look. It appear what you did is just a different way of what I explained above. It works, but I think it has more steps.

I wish I could get this into sheet metal, but cant since it's non-planar I guess.

You need something like that?

Ideally something like this. Not every face needs to be attached, but you get the point. The sheet metal command would be ideal, but I dont know if there is an easy step to get this into sheet metal. Worst case is I do each face separate and glue together instead of bending and gluing.

This one circled is able to bend up both the sides from the bottom face, and glue to top on. Removes a few glue joints.

Like this one maybe?

You have many solutions in SW it depends the strategy you will be apply

Try Convert to Sheet Metal, there is an option to keep body to reference for new features/panels

The part you are trying to make could be created in sheet metal. It would not be formed from one sheet so you need to think about how the sheets would be cut, formed and fixed together. Get some reference to help make the decisions.

To get the flat patterns you will need to do this in sheet metal. It will take some doing. Do the panels individually, and then put the flat patterns in an assembly so you can cut them all out. You will need to exchange your splines for arc approximations. This isn't right, but will maybe get you started.

You can use shell command and then convert it to sheet metal, dusting shell you can keep the required thickness

you do not need 'shell' feature to use convert to sheet metal, less features = more robust model

Oh yes, correct, but usually I delete one or more faces in shell and then convert it to sheet metal. I haven’t tried if it’s possible in convert to sheet metal option.
