Aluminium frame for a camper

Hi guys,
I'm relatively new to CAD and even newer to Onshape, so there's still a lot to learn. Now I'm planning a project in the distant future and have started designing it, but I'm having trouble understanding it. Can anyone tell me how to adapt a tubular frame made of aluminium angles, for example? I tried with the frame script but got stuck because there are too many different angles. Then I tried bent parts, which I think is a better solution, but I'm not getting anywhere. Can someone explain to me what would be the right approach here?
Composite panels with 35mm are used in the frame for understanding.

@timo_afdzaludin Solche Rahmenkonstruktionen mit verschiedemen Winkeln können sehr schnell sehr unübersichtlich werden. Du bist ja schon recht weit gekommen. Vielleicht kann Dir, ausgehend von Deinem grünen Volumenmodell mit den Skizzen auf den Außenflächen, das "Fill" (Füllen) und dann das "Thicken" (Verdicken) Werkzeug helfen. Es erzeugt mit der "Add" (Hinzufügen) Option dann statt einzelner teile ganze Rahmen. Vielleicht müsstest Du die Skizzen zuvor noch etwas darauf anpassen, aber dann kannst Du größere Rahmenelemente bauen. Je nach dem, wie die die Winkelptrofile herstellen möchtest, könnte man auch daran denken, sie als Blechteile zu konstruieren.

Hello @martin_kopplow, thank you very much for the response and the proposed solution. The plan so far was to make aluminum angles for the edges and then weld them at different points, a kind of puzzle system, since the frame already has a certain size, and this would make it easier to manufacture and also repeatable. That’s why I found the idea of creating unfoldings from the parts very interesting, as it would be easier to manufacture and the drawings would also be clearer.

In that case, I recommend using the sheet metal toolset. That will make unfoldings very easy. Good luck!
Thank you, but I'm a bit stuck because it's not really working due to the bevels at the corners and the different angles.
