Polyline Specialist is an AutoCAD add-on which includes advanced editing and processing tools for polyline objects. Polyline Specialist is a productivity enhancement tool for polyline data. It lets you convert arced lines to linear segments, densify and weed vertices, delete and insert a single pick vertex, and interpolate elevations along a 3Dpoly. You can convert zero lengths to points, label vertices and segments, display bulge information, explode wide polylines, convert 3D polylines to 2D format and vice-versa, and automatically join 3D polyline segments. The program also enables you to mass-join 2D polyline segments\; identify zero elevations\; move, stretch, extract, and offset a part of a polyline\; flip the direction of flow\; perform detailed statistical computations.
