# fz_objt_cnstr_multi_spline

Description

Creates multiple 2nd or 3rd degree b-spline curves. Each curve has "pts_per_seg" control points model_type determines if a smooth or facetted spline is created. Note, that the resulting object type is not "Spline" but "Composite Curve" since there are multiple curves.
