Next Post
Here you have the AutoLISP program. Copy it to a text file and save it under the name CRTVW.LSP. Load it into AutoCAD and work with it.
In the next post I'm going to talk about all the functions. I'm going to explain how they work and why they are there.

Warning Don't spend a lot of money on AutoCAD Light. It is only for creating 2D drawings and it doesn't support AutoLISP. There is a very similar CAD program. And that is completely free. The name of the program? DraftSight. How to get it? Do a search on Google for “download DraftSight”. And you will find where you can download the program. |

Only
Create Drawings When your CAD operators don't create the borders of your drawings, a lot of time is saved. You get your drawings much faster. I have created a program that does exactly that. An AutoCAD drawing has been created and the program draws a border around it. If you want to see how the program works, go to YouTube. You'll find the working of the program here: http://www.youtu.be/O8Zy6n9zS8Q Now the AutoLISP program gives you the choice to select the size of your border. You can select A4, A3, A2, or A1. Maybe you already know the size of the border of your drawing. Maybe all your drawings have the size A1. If so. Let me know. That is important. The program finds the proper scale of your drawing. Or do you already know what the scale always is? I can write the AutoLISP program that you want. The price? I will only charge you RM 600.-. That is less than US $ 200.-. |
