BB Pro Boundary Builder for AutoCAD

Description

BB Pro is an AutoLisp program that helps you clean up lines, arcs and open polylines into closed polylines. You need to make the layer you wish to clean the current layer and select the area to clean using the Window command.

BB Pro then attempts to link a collection of lines and arcs into a closed polyline by searching for a line or arc near the endpoint. If more than one candidate is detected, BB Pro zooms into the area and asks the user to select the desired one.

Once complete, your drawing has all clean closed polylines on a boundary layer and leftover lines and arcs on an open layer. Cleanup operations that took hours by hand are done in minutes with BB Pro.

BBPRO only works in the English version of AutoCAD (version 12 through 15).

Applications

BB Pro is ideal for designers of PCBs, microwave circuits, RF circuits and IC packages where closed boundaries are essential for conversion to mask data. It most cases the DXF output of the AutoCAD drawing will be converted either to Gerber or GDSII format - both of which require closed polyines to convert the outline data to commands for the mask making machine.
