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.

Actually the problem is in the boundary of the cylindrical surface the six drills on the side face are made of.

Can you take a look please?

but how can I than "recalculate" the new number of poles, knots, ... because for periodic curves the number and sums are mismatching.

This works:

if (pcurve.rational):
try:
bsc.buildFromPolesMultsKnots(
poles = pcurve.poles,
mults = pcurve.uMults,
knots = pcurve.uKnots,
periodic = pcurve.uPeriodic,
degree = pcurve.uDegree,
weights = pcurve.weights)
except:
bsc.buildFromPolesMultsKnots(
poles = pcurve.poles,
mults = pcurve.uMults,
knots = pcurve.uKnots,
periodic = False,
degree = pcurve.uDegree,
weights = pcurve.weights)
else:
try:
bsc.buildFromPolesMultsKnots(
poles = pcurve.poles,
mults = pcurve.uMults,
knots = pcurve.uKnots,
periodic = pcurve.uPeriodic,
degree = pcurve.uDegree)
except:
bsc.buildFromPolesMultsKnots(
poles = pcurve.poles,
mults = pcurve.uMults,
knots = pcurve.uKnots,
periodic = False,
degree = pcurve.uDegree)
