Creates a new model by applying a double tuck fold to an existing one.
tmod = DBL_TUCK(
mod, plan, line, l, el_size, gap_mini, tan_a
) ;
tmod
The name of the folded model.
mod
The name of the model object to be folded.
plan
The mean plane of the model to be folded.
line
The folding line.
l
The length of the first tuck.
el_size
The minimum element size.
gap_mini
The minimum gap between folded surfaces.
tan_a
The maximum slope of inclined surfaces created around the fold line.
The folding algorithm in described in detail in the Double-Tuck Fold section.
