CurveLoop.CreateViaThicken(CurveLoop, Double, XYZ)

Public Class

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

Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)

Syntax

public static CurveLoop CreateViaThicken(
  CurveLoop curveLoop,
  double thickness,
  XYZ normal
)

Parameters

curveLoop CurveLoop

The input curve loop.

thicknessDouble

The distance between the offset curves created on either side of the input curve.

normal XYZ

The normal vector to the plane used for thickening.

Return Value

CurveLoop
The new curve loop.

Exceptions

Exception

Condition

ArgumentException

The input thickness is too short for a curve. -or- the curve loop is not marked as open.

ArgumentNullException

A non-optional argument was null

InvalidOperationException

Throws if the input curve could not be thickened.

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.
