Convert IGES bspline surfaces to sheet bodies

If on, converts IGES B-spline surfaces to MicroStation sheet entities.

Stitch imported sheet bodies into a solid

If on, converts sheet bodies into solid entities.

Try relaxing tolerance if default is too tight

If on, the looser tolerance allows curves which are not within tolerance to be translated. While inaccurate, the curves are properly placed within the drawing.
