pw::Shell join ?-reject rejectVar? ?-tolerance tol? shell
This action joins as many of the given shells together as possible.
| -reject rejectVar | This optional parameter is a variable name to receive a list of pw::Shell objects that were not used in joining. |
| -tolerance tol | This optional parameter is the fit tolerance. |
| shells | This parameter is a list of pw::Shell objects to join. |
This action returns a list of the pw::Shell objects that were joined.
This command supports progress updates.
pw::Shell getIntersectingFaces shells
This action determines the set of intersecting faces among the provided database shells.
| shells | This parameter is a list of pw::Shell objects. |
This action returns a list of points, where every three represent a triangle that make up the face.
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]

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]
}
