Incomplete import on plain SAT

[marcocecchiscmgroup]

Dear Jens,
this one should be very easy for you.
The attached sat, which presents nothing apparently unusual, crashes on conversion. The reason is simple, it's OCCT failing to create a periodic b-spline when indicated to be non periodic. The fix is simple:

  	periodic = False, \
  	periodic = pcurve.uPeriodic, \

in create createBSplinesPCurve().
With this, the converted step misses the six holes (cylindrical surface with all its bounds) on the side face.
Actually the conversion results in a STEP file which is about half the size of the correct version. Both are included.

Your help here would be much appreciated, thanks in advance.
