MBREAK Software

MBREAK is a handy routine that does the same thing as the AutoCAD BREAK command. The cool part? You can use a selection set of objects to break! Just keep in mind that this routine only works with lines.

Controlling Break Size with FILLETRAD

The size of the break is managed by the FILLETRAD AutoCAD system variable. Be sure to set this up before you dive into using the MBREAK command. You can do this by using the FILLET command's Radius option. And if you're working with arc-type breaks, it will insert an arc between the broken parts of your line. This feature is super useful when you're dealing with diagrams like electrical or piping layouts.

Loading AutoLISP Programs in AutoCAD

Now, let's talk about how to load AutoLISP programs in AutoCAD. There are a couple of easy methods you can try:

Method 1: Using AutoCAD's "appload" Command

You can use AutoCAD's "appload" command for loading your programs. Check out AutoCAD's command reference for more details on how to do this. Once you're all set up, just type MBREAK or MB at the AutoCAD command prompt to get started!

Method 2: Adding Code to "acad*.lsp" File

This method involves adding a line of code to your "acad*.lsp" file like so:

(load "mbreak1")

This will automatically load the program every time you open a new drawing! Just remember, you need to type MBREAK or MB at the command prompt again after that.

Your Acad Files for Different Versions

The names of your acad files depend on which version of AutoCAD you're using:

• AUTO CAD R12: acad.lsp


• AUTO CAD R13: acadr13.lsp


• AUTO CAD R14: acadr14.lsp

IMPORTANT!!!

If you're planning to add anything to your "acad*.lsp" file, make sure you save it under a different name first! This way, you'll avoid any accidental corruption of your original file.
