Convert a tube to sheet metal.

Hello, I would like to be able to convert a square tube to sheet metal.
This way I can see how the tube is actually laser cut, and prevent unnecessary extra processing time.
Is there a way to do this in Onshape at this moment?
I've added example pictures of a part I generated using Solidworks.

Here is a sample of the approach I would use, but there are many different ways of doing it.

You will have to create a small slit running the length of the tube to convert it.0 -

Tried this by creating a open tube as a sheet metal part.
What I need Left, Onshape right.
The way I cut these parts in SW
Cutting it these ways did not work.

Managed to get Onshape to do what I want how I want it.I had to exclude a lot of faces making the process overly complicated. Because the part cant unfold (like tubes cant) I get a warning.
Left = Sketch(inner and outer region) + extrude/add + extrude/remove +sheetmetal/convert(exclude all upper, lower and inner faces + change direction)Middle=[SW part] Sketch(outer region) + Extrude/Thin Feature + Cut + Convert(collect bends)Right=Sketch(outer region) + Sheetmetal(change direction) + extrude/remove (result was failure not 45deg)

Thanks this is by far the best method I have found.

Here you can see other way to do that

emagdalenaC2i said:Here you can see other way to do thatNice method because it preserves the original length. The downfall is it produces the perpendicular extra bit of steel I would like to prevent having. SolidWorks produces that bit as well.
Making the "Extrude_remove" sketch like this prevents this behavior. But is there another way?Because of topological naming of surfaces this method is not usable for a highly configurable part because you would have to keep re-selecting surfaces in the sheet metal model.I've made an example configurable rectangular tube with the method posted by @Wayne_Saunder.0
