formZ SDK | 5.0 API Reference | Project | Modeling | Objects | Control Objects | 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.
