Curvefit is the only polyline optimizer that produces smooth, accurate, tangent linework and simultaneously reduces the number of vertices by an order of magnitude. Curvefit is included in our Automated Mapping Toolkit – MapTools Pro and our Automated 3D Corridor Mapping Toolkit – CoriMap.


  • Reduce drawings 10:1 or more
  • Build accurate, tangent linework
  • Smooth jagged polylines
  • Unattended operations

Curvefit can simultaneously reduce vertices and improve smoothness

Curvefit creates an AutoCAD polyline using both straight and arc vertices. The use of arc segments to replace groups of vertices simultaneously delivers vertex reduction and smoothing. No other linework processor offers this capability. Curvefit is unmatched in its ability to create high quality linework with the absolute minimum vertices.

Automation Ready – Curvefit can operate from the command line using a Dialog Box interface or as a part of more complex automation operations using MapTools Commander – process a drawing or a groups of drawings unattended.
