The notorious FILEDIA variable can cause you to yell at your computer, have chest pains, and make you want to quit for the day. When you change the annotation scale, with MSLTSCALE set to 1, your linetypes will scale with the annotation scale. The MSLTSCALE variable controls the linetype display when in model space. Standing for both Model Space LTSCALE and Paper Space LTSCALE, these are drawing variables. In most cases you want this variable to be set to 1, and since it is a drawing variable, you will need to set this to 1 for every drawing. It is also used with those products for specific functionality. The PROXYGRAPHICS drawing variable is used to tell the drawing to save images of proxy objects (e.g., Civil 3D objects, Architecture toolset objects, etc.). In most cases you want to turn the object into a polyline anyway, and the prompt is an “extra step.” Setting the system variable PEDITACCEPT to 1 will bypass the prompt and turns the object into a polyline automatically. When running the PEDIT command (Polyline Edit), and you select a line or an arc, AutoCAD will prompt you to turn the object into a polyline.

Although this is a system variable, and should only need to be set once, I have found that sometimes the variable can switch to zero when you exit or crash. Setting the variable to 1 will allow you to zoom/pan and “see” where your zooming from/to. The variable can be set to a value of 0-7 I recommend you set it to 1. VTENABLE is a system variable that makes AutoCAD transition between views smoothly or abruptly. The list below explains some of these commands and system variables in detail.

Let’s take a look at some of these commands/variables, and then we will discuss how to automate running them any time you open a drawing with a LISP routine.

Architecture, Engineering and ConstructionĪs I started to use AutoCAD day in and day out (many years ago, wink), I found that sometimes I would run commands or set system or drawing variables many times throughout the day.

Architecture, Engineering & Construction.

I have provided the picture to see what you want to aim for, and the rest is down to a bit of graft! Being self-employed gave me an added incentive to write something if I wanted to start earning any money.

If you can find out how to download the coordinates in a text file, then in the fullness of time, you will be able to your own Lisps.

The routine is a single hit, but if your right click is set to repeat command, then you can carry on clicking (left and right). Then you can set your snap, and click away. When it is loaded successfully, the command line will say C:3DL. Then either type at the command line (load"3dl"), or go through Tools menu - Autolisp - load, and browse till you find it. To run this Lisp, you need to copy the text into NotePad/ WordPad, then to save it as a text file called 3DL.LSP, and put that file where it can be found by AutoCAD's search path, (you have to make sure the file extension is LSP, or change it afterwards). If your data comes in as block, then your snap should be set to Insertion.
