Chapter 3: Create Tab 101Choose Detail > Curves: Control Points > End Control Point todetach the last point from the curve. It is your ending control point.Dragging it will change the shape of the curve at the new endingpoint.Step 2: Click Detail > Curves: Smooth. This smooths thejoint as though the two curves were originally plotted as onecontinuous curve—even though they remain individual curves.The Control Points commands will also toggle the control pointstate off, if selected again.NOTE: Make sure that the point they share is infact one point. (If not, merge or weld the pointsinto one.)NOTE: It is perfectly legal to have only abeginning or ending control point on a curve.HINT: If you plan to use control points on a curve,you should add an extra point at the beginning andend of a curve for that purpose.HINT: If you require a sharper corner anywhere on acurve, simply add an extra point close to the cornerusing Construct > Subdivide : Add Points.Turning Curves into PolygonsSince curves will never be seen by themselves, sometimes youneed to turn them into polygons.To convert a curve into a polygon:Select the curve(s) and choose Construct > Convert: Freeze.Each independent curve will become a distinct polygon. An opencurve will be closed (between its end points) before it is convertedto a polygon.Smoothing Two Overlapping CurvesWhen two curves share the same end point, because of pointmerging or some other reason, the curve may not flow smoothlythrough that point. This can be particularly troubling whendesigning a complex spline cage. You could kill the curve (K),reselect the points and create a new curve, but there is an easierway.The number of points that Modeler will use to approximate thecurve depends on the setting for Curve Division on the GeneralOptions Panel (Modeler > Edit> General Options).To smooth curves sharing a common end point:Step 1: Select the two curves (Polygon Selection mode).
