How it works
In brief, the PlineWeeder runs inside AutoCAD. It allows you to select any number of polylines to process. After which, you select the algorithm by which Pline Weeder will which vertices are unneccesary. You choose the algorithm based on the nature of the polyline data and types of features you want to preserve. For instance, a contour line might be weeded based on the anglular difference between adjacent line segments. Segments, or vertices, that lie more-or-less in a row can be eliminated. Small features below a given tolerence might be disregarded as anomilies of the contouring processing. Whereas, if the polylines represented property boundaries, small angular features or subtle dog-legs might be very significant and therefore a different algorithm would be used in order to preserve these features. Having selected the appropriate algorithm, you would then set the tolerence or tolerences that control the function of the algorithm and ultimately determine to what degree the polylines are weeded. The Pline Weeder then runs the algorithm on the selected polylines and weeds out the unneccesary vertices.
After the weeding is complete, you have the option to view the newly weeded polylines and the original polylines simultaneously. You can toggle either the new or old polylines on and off at will, and compare the difference and visually inspect the results. If the results are not optimal or the polyline have been weeded too severely, you would simply keep the original polylines and re-run Pline Weeder at different tolerences.
