CTiglMakeLoft Class Reference

The CTiglMakeLoft class is used to create loft topologies using cross sections and optional guide curves. By default, the resulting topology is a solid. In order to prevent closing the loft side faces (and making a solid), you can call CTiglMakeLoft::setMakeSolid(false) More...

Member Function Documentation

addGuides()

TIGL_EXPORT void CTiglMakeLoft::addGuides

(

const TopoDS_Shape &

guides

)

This function may be called to add guide curves to the lofting algo. The shape should be either a wire or a Compound consisting of multiple wires

addProfiles()

TIGL_EXPORT void CTiglMakeLoft::addProfiles

(

const TopoDS_Shape &

profiles

)

Should be called to add sections/profiles to the algorithm.

Parameters

profiles

A shape that is either a wire or a compound consisting of multiple wires.

CloseShape()

void CTiglMakeLoft::CloseShape ( )

private

transform the shape to a solid if the correspondig flag is set, transform it to a shell otherwise (wrapper for CTiglPatchShell)

makeLoftWithGuides()

void CTiglMakeLoft::makeLoftWithGuides ( )

private

makeLoftWithoutGuides()

void CTiglMakeLoft::makeLoftWithoutGuides ( )

private

operator TopoDS_Shape &()

TIGL_EXPORT CTiglMakeLoft::operator TopoDS_Shape &

(

)

Perform()

TIGL_EXPORT void CTiglMakeLoft::Perform

(

)

Performs the algorithm. Doesn't need to be called manually.

setMakeSmooth()

TIGL_EXPORT void CTiglMakeLoft::setMakeSmooth

(

bool

enabled

)

setMakeSmooth switches, whether the resulting loft will be ruled or smoothed. This switch only applies, if no guide curves are applied.

Parameters

enabled

Set to true, if smoothing should be enabled.

setMakeSolid()

TIGL_EXPORT void CTiglMakeLoft::setMakeSolid

(

bool

enabled

)

Use the function to adjust, if you want to get a closed solid (inclidung the side caps at the inner and outer profile) or just the surface without caps.

Parameters

enabled

If true, a solid is built.

Shape()

TIGL_EXPORT TopoDS_Shape& CTiglMakeLoft::Shape

(

)
