In this exercise, we will continue our AutoLISP tutorial. This time we are going to use lists and strings. We have learned how to use mathematic equation in AutoLISP to calculate a value. This time we will work with strings. Let us see what are we going to create. We are going to create a […]
AutoLISP Exercise : Create Regular Polygon by Defining Area
I hope you are having fun with our AutoLISP exercises. Last time, we were introduced to use AutoLISP variables and asking users for input. This time we will learn about asking for more user input, then using the input in mathematical equation. The calculation result result will be used to draw an object. Our challenge […]
