Comment 7 for bug 255157

    re-opening this in order to submit a proposal for an enhancement in the ROBO Master output, namely multisplines.
    In the original proposal, each Bezier spline was represented by a separate NURB, even if the Bezier splines were joined with smooth nodes. This led to discontinuities in the slope at each joint (within the ROBO option, not the original option). The new proposal will generate a multispline of indeterminate length as long as all the elements are splines with smooth nodes. The slope will be continuous at internal joints between splines and the multispline will not break apart upon editing in ROBO Master.
    Only the spline-to-spline joint is affected, joints between splines and lines are treated as separate objects, as before.
    Only the file dxf_outlines.py is affected, and it can be used as a direct replacement of the previous file.
    Any feedback would be welcome, particularly from ROBO users.
