Do this appropriately and automatically with the BLADE editor.

It is a good practice to use "indenting" to make code more readable/presentable. The editor will automatically attach the. I created a folder on a USB drive called LISP, so I will navigate to that folder and use* OffsetCircles* for the file name.

The red bar between the line numbers on the left and the new code on the right means those lines have been modified since the last save. We do not want to make one of the most common errors in programming and in CAD in general - SAVE the file! Select the Save icon we all know and love (even though many of you may have never used a floppy disk!). Note: If the colors in the graphic do not match your screen you may have forgotten to delete and retype the quotation marks.

Remaining arguments - the expressions that you would like the defined function to perform.

If the function name starts with "c:", the function name can be typed in directly at the prompt as any other defined command. We will use an empty list until we are ready to discuss this more deeply, later.

This function creates a user defined function that can be used just as the "built-in" functions or as a command. (defun list symbol expression expression expression.) We need to group these lines of code together as "one unit". This can be helpful, especially while getting started, as "typos" may stand out a bit.: We are not going to get into all the benefits of the BLADE editor in this episode but do note that there is some color-coding that occurs. The font in the blog article is not compatible with the BLADE editor in respect to quotation marks. Note: You will need to delete each of the 10 quotation marks, and retype them in.

Copy the 6 lines of code above and paste them into the document window, like so:.

Launch BricsCAD and type BLADE at the prompt.

Storing our LISP programs as individual files is the beginning of the answer to that problem. Not much time would be saved if we had to type in those lines of code each time we wanted to draw a double-offset circle. HELP>Developer Tools>Developer Reference>LISP>Expand LISP (LISt Processing)>Expand BricsCAD LISP Functions (setq OFF (getreal "Enter an offset value: ")) (setq CPT (getpoint "Select a center point: ")) We ended Black LISP - #01 with 6 lines of code that allowed the user to select a point and have a circle centered at that point with a specified radius and another circle also centered on the selected point with radius increased by a specified distance:

Discover numerous ways to get the same result.

Build a new program and exploring numerous new functions along the way.

Continue to work with functions from the previous post.

Use the Help command to understand the syntax and their arguments of LISP functions.

Progress through a series of functions to enhance our knowledge of LISP.

Use the BLADE editor "hands on" within BricsCAD.

This blog post (and a few future posts) we will: But even if you chose not to review the previous post, I feel you will be able to follow along with this episode and pick up some of what was discussed previously. If you are new to this blog, I recommend at least reviewing that blog post, if not reading it in its entirety.

We also looked at the basic use of some introductory functions and how to make use of these concepts. In the first blog post we discussed and learned about LISP terminology, syntax, data types.
