public NwcSectionPlane()

NwcSectionPlane(int, Vector3d, double, bool, NwcSectionAlignment) 

public NwcSectionPlane(int planeIndex, Vector3d normal, double distance, bool isEnabled = true, NwcSectionAlignment alignment = NwcSectionAlignment.Custom)

Parameters

planeIndex int
normal Vector3d
distance double
isEnabled bool
alignment NwcSectionAlignment

Properties

Alignment

Standard alignment of the section plane.

public NwcSectionAlignment Alignment { get; init; }

Property Value

NwcSectionAlignment

Distance

Distance parameter along the normal vector from the origin (plane equation: N . P - d = 0).

public double Distance { get; init; }

Property Value

double

IsEnabled

Whether this section plane is currently active and clipping geometry.

public bool IsEnabled { get; init; }

Property Value

bool

Normal

Surface normal vector pointing towards the retained half-space volume.

public Vector3d Normal { get; init; }

Property Value

Vector3d

PlaneIndex

Index of the section plane (typically 0 to 5 in Navisworks).

public int PlaneIndex { get; init; }

Property Value

int

Methods
