pw:: Shell

pw::Shell join ?-reject rejectVar? ?-tolerance tol? shell

This action joins as many of the given shells together as possible.

Parameters

Returns

This action returns a list of the pw::Shell objects that were joined.

Information

This command supports progress updates.

pw::Shell getIntersectingFaces shells

This action determines the set of intersecting faces among the provided database shells.

Parameters

Returns

This action returns a list of points, where every three represent a triangle that make up the face.

Example

This example looks for face intersections across all shells.  If intersecting faces are detected, they are marked with a point that is placed at the centroid of the intersecting cell.

Code

set shells [pw::Database getAll -type pw::Shell]
set pts [pw::Shell getIntersectingFaces $shells]
set numCells [expr [llength $pts] / 3]
for {set i 0} {$i < $numCells} {incr i} {
  set bi [expr $i * 3]
  set vec [pwu::Vector3 zero]
  for {set j 0} {$j < 3} {incr j} {
    set vec [pwu::Vector3 add $vec [lindex $pts [expr $bi + $j]]]
  }
  set pt [pw::Point create]
  $pt setPoint [pwu::Vector3 divide $vec 3]
}

$shell getFaceCount

This action gets the number of faces in the shell.

Parameters

none

Returns

This action returns the number of faces in the shell.

$shell getFaceTriangles index

This action gets the vertices of the triangles for a face in the shell.

Parameters

Returns

This action returns a list of points, where every three represent a triangle that make up the face.

$shell getFaceTrianglesList

This action gets the vertices of all the triangles for a face in the shell.

Parameters

This action has no paramaters.

Returns

This action returns a list of three points, where every three points represent a triangle that make up the face.

$shell getBoundaryCount

This action gets the number of boundaries of the shell.

Parameters

none

Returns

This action returns the number of boundaries of the shell.

$shell getBoundary index

This action gets a shell boundary.

Parameters

Returns

This action returns a boundary.

$shell getBoundaries

This action gets a shell boundary list.

Parameters

This action has no parameters.

Returns

This action returns a boundary list.

$shell extractBoundary index

This action extracts a curve from the boundary of this shell.

Parameters

Returns

This action returns a new pw::Curve object.

$shell extractBoundaries

This action extracts the curves from the boundaries of this shell.

Parameters

This action has no parameters.

Returns

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

$shell extractCurves ?-boundariesOnly? bend_angle

This action extracts curves from edges of this shell where the bend angle is greater than the given angle.

Parameters

Returns

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

$shell extractLines ?-boundariesOnly? ?-shellCount shellsVar? ?-curveCount curvesVar? bend_angle

This action extracts lines from edges of this shell where the bend angle is greater than the given angle.

Parameters

Returns

This action returns a list of XYZ points, with pairs of points for the edges.

$shell split bend_angle

This action splits this shell where the bend angle is greater than the given angle.

Parameters

Returns

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

This action will return a list of shells split by the given plane.

Parameters

Returns

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

$shell flipOrientation

This action flips the orientation of this shell.

Parameters

none

Returns

This action returns nothing.

$shell alignOrientation ?-tolerance tol? shells

This action aligns the normal orientation of the given shells with this shell.  If any shells in the given list are not connected within the given tolerance to this shell, they will be ignored.

Parameters

Returns

This action returns nothing.
