combine points to a fluent line

I don't think you'll be able to get fluid lines and arcs from a point data set? What you can do in SW is create a spline from a imported data set. Insert/Curve/Curve Through XYZ Points

Otherwise someone may have a macro for importing lines to do point-point or just the points to do the lines and arcs manually?

Or, there maybe a script, macro or plugin for the DWGeditor (acad) to import points as lines?

Dirk,

I guess you want to create a closed curve (spline) and approximate it with tangent arcs. This would be two mouse clicks in Mastercam, but you obviously don't have that.

I think Rhino will do the same thing. They have a full featured evaluation for download.

You could probably write a LISP routine for ACAD. Or maybe you could find someone whos willing to share theirs.

If you get the demo version of Rhino - it can be done in Rhino by fitting a curve to the points (under the curve menu) and then using the convert to arcs function.
