CreateViaThicken Method (CurveLoop, Double, XYZ)

Creates a new closed curve loop by thickening the input open curve loop with respect to a given plane.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 22.0.0.0 (22.1.0.0)
Since: 2015

Syntax

C# 
public static CurveLoop CreateViaThicken(
	CurveLoop curveLoop,
	double thickness,
	XYZ normal
)
Visual Basic 
Public Shared Function CreateViaThicken ( _
	curveLoop As CurveLoop, _
	thickness As Double, _
	normal As XYZ _
) As CurveLoop
Visual C++ 
public:
static CurveLoop^ CreateViaThicken(
	CurveLoop^ curveLoop, 
	double thickness, 
	XYZ^ normal
)

Parameters

curveLoop
Type: Autodesk.Revit.DB CurveLoop
The input curve loop.
thickness
Type: System Double
The distance between the offset curves created on either side of the input curve.
normal
Type: Autodesk.Revit.DB XYZ
The normal vector to the plane used for thickening.

Return Value

The new curve loop.

Remarks

The new loop will be created via offsets of the input curve loop (in the plane of the normal vector) with the endpoints connected with lines.The original curve loop will be at the center of the new loop.

If the curve loop contains curves such as elliptical segments or splines, it is possible the offset creation will fail if Revit will not be able to trim contiguous curves to meet one another. If the offset is successful, offsets of those curve types will be created as HermiteSplines.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentException The input thickness is too short for a curve. -or- the curve loop is not marked as open.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was null
Autodesk.Revit.Exceptions InvalidOperationException Throws if the input curve could not be thickened.
