KeyCreator / Create / SplineSplineSplineThe features available from the Create>Spline drop-down and palette submenus allow you to create various spline types. Start and End Condition MenuThe Start and End Condition Menu appears in the Conversation bar frequently throughout spline creation. 2D OpenUse this function to create a 2D open-ended spline that lies within a plane. 2D ClosedUse this function to create a closed 2D cubic parametric spline, which lies within a plane and with specified node locations and tangencies at its end points. 2D AutoUse this function to create a 2D spline automatically through a path of minimum distance point entities, projected to the current construction plane. 3D OpenUse this feature to create a 3D cubic parametric spline, or a true 3D curve with nodes that do not lie in the same plane. 3D ClosedUse this feature to create a 3D cubic parametric spline, or a true curve that begins and ends at the first point selected and with specified node locations and tangencies at its end points. 3D AutoUse this feature to create a 3D spline automatically through a path of minimum distance point entities in 3D space. NURBS Through PositionsUse this feature to create a generic rational B-spline curve by through positions. NURBS Control PositionsUse this feature to create a generic rational B-spline by inputting the vertices of a control polyline. HelixUse the NURBS Helix function to create a 3D spline that simulates a helix curve with an orientation that you define. NURBS SpiralThis function allows you to create a constant 2D spiral-shaped curve. NURBS from PolylineThe NURBS From Polyline function allows you to convert polyline entities into splines. NURBS Blend CurveThe NURBS Blended function can be used to create a single segment spline that bridges the gap between any two curve entities. NURBS ChainUse the NURBS Chain to Spline function to convert a chain of curves into a single spline. NURBS from Point-VectorUse NURBS Point and Vector to create splines by point and vector input. NURBS from DataThe NURBS From Data function is used to create splines from a file of point data. OptionsNurbs Options Explained CloseChoose to create Nurbs Curve as an open or closed curve |
