Simetry of a set of point gives too much error
<< Beatriz Beraza  --  05/31/07  18:10:00>>
In part program attached I measure four diameters and construct
a point in each of them. Then I construct a set with 2 of them and
ask for the simetry of this set to a defined axis.  With point 3 and 4
the error is of more than 6 mm. When I ask for the distance between the medium point and the axis the result is aceptable instead.
If I construct a set with all points or 2 lines and ask for their simetry
to the axis the result is aceptable too.
Is this an error or the result makes sense?

Paola,
I have modified the way the measurement vector is calculated when the datum is a line.  The measurement vector is the cross of the datum vector and the workplane vector.  The symmetry now gives the same results when using a line datum as it does for a plane datum.   I have modified the program (attached in PLANITUD 1.zip) to construct a plane perpendicular to LIN1 and passing through CIR1.  I then compared the symmetry results when using EJE (constructed line) as the datum and when using the constructed plane as the datum.  Both legacy and FCF symmetry now give the same results for both datum types.
I did not modify textual_analysis(...) so you may want to verify that this reports correctly.  Please review my changes.
