 Return type:
 Returns:

 isInPlane(tolerance, normalVector, valD, recalculateD)
Works similarly to
isPlanar()
, but checks planarity with respect to given normal or given plane (if plane equation D is specified  see below). If given normal is the zero vector, the normal used to check the planarity is computed using Newell’s method as inisPlanar()
. valD is a reference to a value of D in the plane equation AX + BY + CZ = D. It can be used to make sure that multiple pieces lie in the same plane. If ‘recalculateD’ is set toFalse
, the passed in value of D will be used in the calculation. If ‘recalcualteD’ is set toTrue
, the passed in value is ignored and is instead automatically calculated (and returned in the second position of the returned tuple). A useful calling pattern for ensuring coplanarity is to get valD computed on the first call to the function setting recalculateD toTrue
, and then use this value for future calls with recalculateD toFalse
. Parameters:
 Return type:
 Returns:
A tuple containing a boolean, tuple, and float representing: 1) Whether or not the area is in plane; 2) The normal vector returned; and 3) The value ‘D’. Note: If recalculateD is
False
, the tuple returned will only contain the boolean and vector tuple (i.e. ‘valD’ is not returned).
 isPlanar(tolerance)
Returns
True
if this is planar within the given tolerance, andFalse
otherwise.The planarity condition is computed by the following algorithm. The normal vector <A, B, C> is determined by the vertices of this area using Newell’s method. For the first point (x’, y’, z’) of this area, we compute D’ = Ax’ + By’ + Cz’. Then, this area is planar if and only if every subsequent point (x, y, z) of this area gives a D = Ax + By + Cz, that is within the tolerance amount of D’. That is,  D  D’  <= tolerance.
If the specified tolerance is negative, then this method always returns
True
.
 measureExists(measureName)

True
if the specified measure exists andFalse
otherwise. If the ‘measureName’ parameter is not specified then the default measure is checked.

 Return type:
None
 removeMeasure(measureName)

 Parameters:

 Return type:

Remove some traits at the top level: regex == <string>
Remove all traits at all levels: regex ==

kFME_RecurseSome
<string>
For example, specifying regex == NULL for a multisurface will remove all traits at the root level of the multisurface, whereas specifying regex ==
kFME_RecurseSome
<string> will remove all traits from all levels of the multi surface that match <string>. If <string> is an illegal regular expression, no traits will be removed. Return type:
