NURBS

Discussion in 'AutoCAD' started by S³awek Kacprzykowski, Apr 27, 2004.

  1. Hi,
    I am designing an application which uses DXF files and I have to
    interpret DXF data concerning NURBS ("SPLINE" command in AutoCAD). I have
    mathematical background of them, but I don't know how to incorporate values
    of knot, control point and fit tolerances (group codes 42, 43 and 44 in DXF
    file) into curve equations.
    I will be very grateful for some references and information explaining
    this problem.
