pw:: Point

pw::Point create

This action creates a new database point object.

Parameters

none

Returns

This action returns a new pw::Point object.

$point setPoint point

This action sets the position of this database point.

Parameters

Returns

This action returns nothing.

$point setAveragePoint points

This action sets the position of this database point to the average of the given points in cartesian space.

Parameters

Returns

This action returns nothing.

$point getPoint

This action gets the control point of this database point.

Parameters

none

Returns

This action returns the control point.

$point getPosition ?< -parameter | -index > value?

This action gets the position in the defining space of the point at the given parameter or index.

Parameters

Returns

This action returns the same point for all valid values.  The returned point (may be in the form “u v dbentity”).

Example

This example gets the point’s position.  $surface is referencing an existing database surface.

Code

set point [pw::Point create]
$point setPoint [list 0.5 0.6 $surface]
puts "\{ [$point getXYZ] \}"
puts "\{ [$point getXYZ -index 1] \}"
puts "\{ [$point getXYZ -parameter 0] \}"
puts "\{ [$point getXYZ -parameter {0 0}] \}"

Output

{ 0.5 0.6 ::pw::Surface_4 }
{ 0.5 0.6 ::pw::Surface_4 }
{ 0.5 0.6 ::pw::Surface_4 }
{ 0.5 0.6 ::pw::Surface_4 }

$point getXYZ ?< -parameter | -index > value?

This action gets the position of the point in model space at the given parameter or index

Parameters

Returns

This action returns the same XYZ vector for all valid values.

Example

This example gets the point’s XYZ location.  $surface is referencing an existing database surface.

Code

set point [pw::Point create]
$point setPoint [list 0.5 0.6 $surface]
puts "\{ [$point getXYZ] \}"
puts "\{ [$point getXYZ -index 1] \}"
puts "\{ [$point getXYZ -parameter 0] \}"
puts "\{ [$point getXYZ -parameter {1 1}] \}"

Output

{ -19.551259370339967 6.9502396184800865 -13.487247573541483 }

$point getDefaultProjectDirection

This action gets the default projection direction for this point.

Parameters

This action has no parameters.

Returns

This action always returns the vector {0 0 1}.

Example

This example gets the point’s default projection direction.  $point is referencing an existing database point.

Code

puts "\{ [$point getDefaultProjectDirection] \}"

Output

{ 0.0 0.0 1.0 }

$point isConstrained

This action checks to see if the point is database constrained.

Parameters

This action has no parameters.

Returns

This action returns a boolean.

Example

This example checks to see if the point is database constrained.  $surface is referencing an existing database surface.

Code

set point [pw::Point create]
$point setPoint [list 0.5 0.5 $surface]
puts [$point isConstrained]
$point setPoint {10.5 11.5 12.5}
puts [$point isConstrained]

Output
