Detailed Description

Curve2d Curve2d.hxx cadex/Geom/Curve2d.hxx.

Base class for 2D curves.

2D curves are used to represent curves in surface parametric domains (p-curves). They are used by edges owned by faces.

For detailed description refer to 3D counterpart Curve.

DN()

manufacturingtoolkit.CadExMTK.Geom_Curve2d.DN	(		self,
			theParameter,
			theDerivativeOrder,
			theValue,
			theD )

Returns true if calculation was passed succsesfully, the returned vectors gives the value of the derivative for the order of derivation theDerivativeOrder.

Otherwise returns false. Throws exception if the continuity of the curve is not CN.

Parameters:

• theDerivativeOrder must belong to range [0, 3].
• theD should have enough size to store theDerivativeOrder derivatives.
