Fix error The number of control points must be the same as the number…

[dsn27]

Wrong parameter was set here. It should be null if the spline has no weights.

CADability/CADability/ExportDxf.cs

Lines 170 to 173 in 0117f6f

	if (bspline.HasWeights)
	return new netDxf.Entities.Spline(poles, bspline.Weights, knots, (short)bspline.Degree, bspline.IsClosed);
	else
	return new netDxf.Entities.Spline(poles, Array.Empty<double>(), knots, (short)bspline.Degree, bspline.IsClosed);

Fix the error:

Exception Source: CADability
Exception Type: System.ArgumentException
Exception Message: The number of control points must be the same as the number of weights.
