So far I have made the initial design in Fusion.
This week I will make the flat patterns for cutting out on my 80w Laser. The model has vectored thrust. A total of 6 servos will be used.
2 aeleron
2 elevator
2 vectored thrust

Oops the vertical stabs are not even. I fixed it, I had used the wrong plane to mirror the left stab to the right one.

Looking great!

The ply parts required for optional thrust vectoring. Only ply parts on the model.

Looking good! BTW @Mr Man uses Onshape to extract the skins off the 3D model for the 2D plans.

Is that a plugin for Fusion.

Is that a Fusion 360 plugin? I do it differently.
But always like seeing different techniques. My way works for me, and it’s easy, but I’m sure there are other ways that might be better.

Not sure, @Mr Man? I think its a separate program and he uploads it into it.....

Its a completely different program, and I design everything in it.

An update on the F-22. I have been churning through making the flat patterns for the laser cut files.
I have only the canopy and some tail pieces to finish up. Looks like it will take about 8 sheets of foam board.

My laser can’t quite cut a full 20” x30” sheet of foam board. I loose a little bit of bodreder space, not much.
Unfortunately, the wing flat pattern requires a full sheet, unless I break up the wing somewhere.
You can see in the pic how the top 2 sheets are larger.
I need to revisit this and section the wing somewhere without compromising strength.

How do you flatten surfaces in fusion?

I don’t do that in Fusion. I export the objects and use 3rd party software. There are several options out there that can flatten shapes.once flattened, I import them back into Fusion.

I see

F-22 Flat patterns done, ready to export to laser software for cutting out. Good thing I have a box of foam board.

Cool!

A stack of parts fresh off the laser for the weekend build. Tail fin in hand for scale reference.

Amazing! I can't wait to see it all come together.

I love the SR-71 in the background.
