Gets the dimension of the object. The dimension is typically three. For parameter space trimming curves the dimension is two. In rare cases the dimension can be one or greater than three.
Gets or sets the domain of the curve.
Returns true if the Brep.TryConvertBrep function will be successful for this object
Gets a value indicating whether or not this curve is a closed curve.
true if object can be accurately modified with "squishy" transformations like projections, shears, and non-uniform scaling.
Gets a value indicating whether or not this curve is considered to be Periodic.
Tests an object to see if it is valid.
...
Useful for switch statements that need to differentiate between basic object types like points, curves, surfaces, and so on.
Evaluates point at the end of the curve.
Evaluates point at the start of the curve.
True if "this" is a curve is reversed from the "real" curve geometry
Gets the number of non-empty smooth (c-infinity) spans in the curve.
Evaluate unit tangent vector at the end of the curve.
Evaluates the unit tangent vector at the start of the curve.
Gets the amount of user strings.
The desired dimension.
true if the curve's dimension was already desiredDimension or if the curve's dimension was successfully changed to desiredDimension; otherwise false.
Changes the dimension of a curve.
The orientation of this curve with respect to world XY plane.
Determines the orientation (counterclockwise or clockwise) of a closed, planar curve in the world XY plane. Only works with simple (no self intersections) closed, planar curves.
The plane in which to solve the orientation.
The orientation of this curve with respect to world XY plane.
Determines the orientation (counterclockwise or clockwise) of a closed, planar curve in a given plane. Only works with simple (no self intersections) closed, planar curves.
Curve parameter to evaluate.
Number of derivatives to evaluate, must be at least 0.
An array of vectors that represents all the derivatives starting at zero.
Evaluate the derivatives at the specified curve parameter.
Curve parameter to evaluate.
Number of derivatives to evaluate, must be at least 0.
Side of parameter to evaluate. If the parameter is at a kink, it makes a big difference whether the evaluation is from below or above.
An array of vectors that represents all the derivatives starting at zero.
Evaluate the derivatives at the specified curve parameter.
An object of the same type as this, with the same properties and behavior.
Constructs a deep (full) copy of this object.
If true, a physically accurate bounding box will be computed. If not, a bounding box estimate will be computed. For some geometry types there is no difference between the estimate and the accurate bounding box. Estimated bounding boxes can be computed much (much) faster than accurate (or "tight") bounding boxes. Estimated bounding boxes are always similar to or larger than accurate bounding boxes.
The bounding box of the geometry in world coordinates or BoundingBox.Empty if not bounding box could be found.
Bounding box solver. Gets the world axis aligned bounding box for the geometry.
true if this curve can be represented as a polyline; otherwise, false.
Several types of Curve can have the form of a polyline including a degree 1 NurbsCurve, a PolylineCurve, and a PolyCurve all of whose segments are some form of polyline. IsPolyline tests a curve to see if it can be represented as a polyline.
false if object cannot be converted to a deformable object. true if object was already deformable or was converted into a deformable object.
If possible, converts the object into a form that can be accurately modified with "squishy" transformations like projections, shears, an non-uniform scaling.
Angle of rotation in radians.
Direction of the axis of rotation.
Point on the axis of rotation.
true if geometry successfully rotated.
Rotates the object about the specified axis. A positive rotation angle results in a counter-clockwise rotation about the axis (right hand rule).
NURBS representation of the curve on success, null on failure.
Constructs a NURBS curve representation of this curve.
The NURBS representation for this portion of the curve is returned.
NURBS representation of the curve on success, null on failure.
Constructs a NURBS curve representation of this curve.
Transformation to apply to geometry.
true if geometry successfully transformed.
Transforms the geometry. If the input Transform has a SimilarityType of OrientationReversing, you may want to consider flipping the transformed geometry after calling this function when it makes sense. For example, you may want to call Flip() on a Brep after transforming it.
Start of the trimming interval. Portions of the curve before curve(t0) are removed.
End of the trimming interval. Portions of the curve after curve(t1) are removed.
Trimmed portion of this curve is successful, null on failure.
Removes portions of the curve outside the specified interval.
[boolean, Polyline] (boolean) true if this curve can be represented as a polyline; otherwise, false. (Polyline) If true is returned, then the polyline form is returned here.
Several types of Curve can have the form of a polyline including a degree 1 NurbsCurve, a PolylineCurve, and a PolyCurve all of whose segments are some form of polyline. IsPolyline tests a curve to see if it can be represented as a polyline.
Static createControl points as an array of arrays containing three numbers or a Point3dList.
Degree of curve. The number of control points must be at least degree+1.
Constructs a curve from a set of control-point locations.
