Generate3dPathSection(object[], object[], object[], double, double, object[], object[], bool, bool, object)

Create a new Polyface object following a given path and drawing a given section

public object Generate3dPathSection(object[] section2d, object[] sectionBasePoint2d, object[] path, double SectionAngle, double SectionScale, object[] startVector, object[] endVector, bool TopBottomFaces, bool drawit, object entities)

Parameters

section2d object[]

Array of one or more closed 2d sections

sectionBasePoint2d object[]

A point relative to sections array that defines the origin of sections. This point will run over the path line

path object[]

An array of points in real world Coordinate System

SectionAngle double

Angle in radians that sections will be rotated around base point before they mapped on the path line.

SectionScale double

The ending scale of the section object(the section object will start following the path with scale=1.0 and will end with scale=SectionScale).Set it to 1 for no scale.

startVector object[]

The extrution vector of the plane of the start section.If it is null the vector of the start segment is used.

endVector object[]

The extrution vector of the plane of the end section.If it is null the vector of the end segment is used.

TopBottomFaces bool

Defines if the start and end caps of the path will be filled.

drawit bool

Defines if the polyface object will be drawn.

entities object

The entities collection where the line will be added. This can be the entities of layout or a block.If not defined then the created entity is added to active layout.

Returns

object

The created object
