PointsOn

The PointsOn command displays control points.

Control points are coefficients of NURBS basis functions. Sometimes also called control vertex or node.

Control points are used as "grips" on objects such as curves, surfaces, lights, hatch boundaries, and dimensions and cannot be separated from their objects.

Note

• When you control-point edit curves that are smooth and consist of several curve segments joined together, the curve will fuse into a single curve that cannot be exploded. If necessary you can use the Split command with the Point option and Knot object snap to break the curve into segments.
• To ensure the seams of polysurfaces do not accidentally crack open, polysurface control points cannot be turned on. To control-point edit a polysurface, Explode the object into separate surfaces first or use the ExtractSrf command to separate the surfaces you want to edit.
• While control points are on, they can be selected and deleted. This changes the shape of the curve or surface.

The PointsOff command turns off control points and edit points display.

The PtOffSelected command turns off control points and edit points for selected objects.

The SolidPtOn command turns on grips at the ends of surface and joined polysurface edges, including closed solids.

The EditPtOn command displays edit points on the curve evaluated at knot averages.
