Creating and Managing Curves

	This chapter deals with curve creation and management using the FreeStyle Shaper workbench.
	See also the FreeStyle Dashboard tools as they affect the curve creation and modification, see Dashboard Toolbar.
	Create associative 3D curves: specify the curve creation mode (pass through specific points, specify the curve degree and smoothen the curve through points, or defining the curve control points), and click the space to indicate the curve definition points.
	Creating associative 3D curves on a scan: select one or more scans, specify the curve creation mode, and click the space to indicate the curve definition points.
	Creating associative 3D curves on a cloud of points: select points on the cloud to indicate the curve definition points.
	Create Associative Isoparametric Curves: select a surface and move the cursor over the surface to reveal the isoparametric curves.
	Create free form curves on surfaces: select a surface, specify the curve creation mode (interpolation or smoothening in relation to the selected points), click definition points on the surface, and double-click to end the curve.
	Project curves: select a curve, the surface on which it is to be projected and specify projection parameters
	Create blend curves: select two curves, activate their options display and use the contextual menu on the displayed text to modify the continuities and tension, and manipulate the control points to define the blending point.
	Create a styling corner: select two curves and set the radius value.
	Match curves: select two curves, activate their options display and use the contextual menu on the displayed text to modify the continuities and tension, and manipulate the control points to define the matching point.
	Extrapolate curves: select a curve, specify the extrapolation mode, and enter the extension value.
	Extend curves: select a curve, specify the extension mode, and enter the extension value.
	Break Curves: select curves and specify the breaking options using curves.
	Concatenate curves: select a multi-cell curve and set the tolerance value
	Fragment curves: break a multi-arc curve into several mono-arc curves
	Approximate/segment procedural curves: select a curve, specify the approximation tolerance, and the resulting curve maximum orders and/or segments.
