Mesh3DFactoryCreateExtrudedMeshGeometry(IListPoint, Boolean, Vector3D, Vector3D, Vector3D, ExtrudeTextureCoordinatesGenerationType, Boolean, Boolean) Method

public static MeshGeometry3D CreateExtrudedMeshGeometry(
	IList<Point> positions,
	bool isSmooth,
	Vector3D modelOffset,
	Vector3D extrudeVector,
	Vector3D shapeYVector,
	ExtrudeTextureCoordinatesGenerationType textureCoordinatesGenerationType = ExtrudeTextureCoordinatesGenerationType.Cylindrical,
	bool addBottomTriangles = true,
	bool addTopTriangles = true
)

Parameters

positions  IListPoint

IList of 2D position that define the polygon that is used as the bottom and top surface

isSmooth  Boolean

If true than the mesh appears smooth, if false the edges are sharp

modelOffset  Vector3D

Vector3D that defines an offset of the model - offset is added to each position

extrudeVector  Vector3D

Vector3D that defines the extrusion direction and the distance from the start and end surfaces

shapeYVector  Vector3D

Vector3D that defines the 3D direction of the y axis in the positions list

textureCoordinatesGenerationType  ExtrudeTextureCoordinatesGenerationType  (Optional)

type of texture geometry generation (Cylindrical by default)

addBottomTriangles  Boolean  (Optional)

when true (by default) the triangles for the bottom part of the object are created, otherwise the bottom part is opened

addTopTriangles  Boolean  (Optional)

when true (by default) the triangles for the top part of the object are created, otherwise the top part is opened

Return Value

CreateExtrudedMeshGeometry creates a MeshGeometry3D that represent an extruded 3D objects that is defined with 2D polygon (defined by positions) and that is extruded by using extrudeVector.

This method uses Triangulator to create 3D surface from 2D positions.

NOTE:
Because CreateExtrudedMeshGeometry is calling CreateTriangleIndices method (defined in Ab3d.Utilities.Triangulator class), it can throw FormatException when positions are not correctly defined - for example if lines intersect each other.
