Fillets–another approach using AutoLISP

Tommy Holder submitted a different approach to creating fillets–one that includes drawing the lines. For the earlier routine, see “Reduce mouse clicks and increase productivity with AutoLISP.”

Tommy’s approach is unique, I think. Instead of drawing the lines first, the AutoLISP routine prompts you for points, which are the endpoints of the lines. Here are the steps:

1. Download fl.lsp. FL.lsp (click to download)
2. Unzip the file.
3. Use the APPLOAD command to load fl.lsp in a location that is in AutoCAD’s support file search path.
4. On the command line, type fl and press Enter.
5. At the Enter points : prompt, specify the first line’s start point.
6. The prompt repeats, so specify the first line’s end point (which is also the second line’s start point)
7. Next, specify the second line’s endpoint and press Enter.
8. At the Enter BEND RADIUS <1.0000>: prompt, enter the fillet radius and press Enter.
