So, that’s it… The problem isn’t with the Rhino export engine/algorithm at all but rests squarely within the (Autodesk AutoCAD) programmers’ specification(s) for the DWG &/or DXF file formats that simply do not allow for joined 3D polylines that include one or more arcs (and convert any/all 3D contouring toolpath data containing arcs to splines). Thank you for your time and attention in this perplexing matter. What we are doing-manually developing 2-1/2 dimensional edge and profile contouring toolpaths and how we are doing it-may seem unnecessarily “old school” but we have our reasons for wanting to teach our students these geometrically-based problem solving and product development skills. I apologize for this being so long and involved.

Note #5: Currently using Rhino 5 (I can’t get the V6 license (re)activated for my office PC until tomorrow). We would just like Rhino to squirt back the arc and line data we developed… but with all the contour polycurves tied together and in DWG or DXF format. Short a $17K controller lobotomy/upgrade, we are limited to DXF and DWG data input. Note #4: Our CNC router’s CAM system version can’t accept STEP or IGES. Note #3: The Rhino-exported “toolpath of ten thousand segments” CNC toolpath data runs but the export geometry (a) is simply huge compared to the simple and elegant original data and (b) has way too many random “stop-starts” inevitable with segmented data. As long as the polycurve is not exploded, everything always blows up the underlying tangent arcs and lines data into segments. Note #2: I have run numerous tests using the “Convert” command with different settings using the CAM Imperial and other export schemes (including the R12 and R14 format factor).

We know how to create the necessary geometry. Everything is tangent the data is really clean. Note #1: the original contouring data is “G-Code friendly” arc and straight line-only data.
