Creates a new model obtained by partial folding from the model given in argument.
fmodel = OPEN_FOLD(
model, plan, line, flag, angle
) ;
fmodel
The folded model.
model
The model to be folded.
plan
The mean plan of the model to be folded.
line
The fold line.
flag
An integer flag describing the position of the rotation axis with respect to the airbag:
outer surface
medium fiber
inner surface
All other values are considered erroneous.
angle
The rotation angle expressed in degrees.
The algorithm of folding is described with more detail in the Open Fold explanation.
