Do you know, that… ?
Something, which in practice it is relative easy to do, SolidWorks program can be challenging. See how to perform flattening the tube by means of operations Deformation.
In the first step, I create while adding the offset – operation create an object, the edges of which will use the moment.
In the second step, using the same sketch intercede Split line.
Then the object deforms the pipe. using deformation like Curve-curve. Seems, it would be more sensible to use a deformation pressing surface – However, this method gives a disproportionately worse result.
To give the deformed tube realism, I use additional bending. The operation is thus defined, that the axis of the bending deformation of the wall.
The final result below.
