pw:: SurfaceTrim

pw::SurfaceTrim createFromSurfaces surfaces

This action automatically creates new database trim surfaces using the given surfaces and its limits as the boundaries.

Parameters

Returns

This action returns a list of new pw::SurfaceTrim objects.

pw::SurfaceTrim createFromCurves curves

This action automatically creates new trim surfaces using the given intersection, projection and boundary curves as boundaries.  The surfaces that are trimmed are those on which the curves depend.

Parameters

Returns

This action returns a list of new pw::SurfaceTrim objects.

pw::SurfaceTrim getBoundariesFromCurve <curve>

This action gets all trim surface boundaries that are supported by the given pw::Curve object.

Parameters

Returns

This action returns a list of boundaries.

$tsurf getPosition ?-parameter? value

This action gets the position in the defining space of the surface at the given parameter.

Parameters

Returns

This action returns a point giving the position on the surface.

$tsurf getXYZ ?-parameter? value

This action gets the position in model space of the surface at the given parameter.

Parameters

Returns

This action returns an XYZ vector.

$tsurf getBoundaryCount

This action gets the number of boundary curves of the trim surface.

Parameters

none

Returns

This action returns the number of boundary curves of the trim surface.

$tsurf getBoundary index

This action gets a trim surface boundary.

Parameters

Returns

This action returns a boundary.

$tsurf getBoundaries

This action gets a trim surface boundary list.

Parameters

This action has no parameters.

Returns

This action returns a boundary list.

$tsurf getBoundaryCurve index

This action gets the pw::Curve object that serves as the trim surface boundary.

Parameters

Returns

This action returns a pw::Curve object.

This action gets the pw::Curve objects that serve as the trim surface boundaries.

Parameters

This action has no parameters.

Returns

This action returns a pw::Curve object list.

$tsurf getBoundaryGroups ?-usage use? ?-loop type? ?-untrimable?

This action gets the groups of boundaries of the trim surface.  The types of groups can be limited by the optional parameters

Parameters

Returns

This action returns a list of boundary groups, with each boundary group represented as a list of boundary indexes.

$tsurf untrimBoundaries indices

This action untrims the boundaries of a trim surface.

Parameters

Returns

This action returns nothing.

Information

Untrimming a boundary will cause all boundaries in the boundary’s group to be untrimmed.  If the boundary is not in an untrimmable group, the action will error and no boundaries will be untrimmed.

$tsurf getInteriorCurves

This action gets all the curves that are at least partially on the interior of the trim surface, but not used in the boundaries.

Parameters

This action has no parameters.

Returns

This action returns a list of pw::Curve objects.

$tsurf getSurfaceTrims

This action returns itself.  It exists primarily for completeness to match the same function for pw::Quilt and pw::Model objects.

Parameters

This action has no parameters.

Returns

This action returns itself.

$tsurf getSurface

This action gets the surface being trimmed.

Parameters

none

Returns

This action returns a pw::Surface object.

$tsurf getQuilt

This action gets the quilt that contains this trim surface.

Parameters

none

Returns

This action returns a pw::Quilt object.

$tsurf getModel

This action gets the model that contains this trim surface.

Parameters

none

Returns

This action returns a pw::Model object.

$tsurf isolate

This action split the trim surface’s quilt and model so that this trim surface is in its own quilt and model.

Parameters

none

Returns

This action returns the new pw::Model object that contains the trim surface.
