For blocks, the rotation point is the insertion point of the block. For the first two, the alignment direction is the X direction of the selected Coordinate System.

Autocad callout lisp. The important thing to remember is that the order of the values is consistent with what we already know. Examines two lines and returns the point where they intersect even if they do not physically cross one another. Note: values in expressions must be enclosed in quotes whereas variable names are not. When you used setq a getpoint you assigned the X and Y coordinate numbers to variable a.
That Variable now is a list that may look like 5 If you want to look at the list in variable a , AutoLISP gives you a convenient way to do that from the command line. The primary command for taking a list apart, car gives you the first element of a list.
If the value of variable a is the list 5 10 , then:. This is the secondary command for taking a list apart. If the value of variable a is the list 2 5 7 9 11 , then:. This always produces the second element of a list. Assuming the value of variable a is the list 5 10 , then:. This always produces the third element of a list. Assuming the value of variable a is the list 3 7 5 then:.
Changes a string of text from lower case to upper case, leaving upper case characters as they are. Returns a part of a string, from a specified position, ending either at the end or another specified position. For example, if a group of items is preceded by an apostrophe, it is treated as a list. Returns an angle between two points in radians. To use that angle in AutoCAD you have to convert it back to decimal degrees.
But a is not the correct rotation angle because it is in radians. Returns the nth element in a list, where n is the number of the element to return. Zero is the first element.
Often used with the subst function; the assoc function lets you search for a specific element, then assign that element to a variable. Lets assume variable b is the list 10 5. You want to pull out the entire element and assign it to a variable c. This assigns the entire element containing the 40 in the list b to variable c. Now c is a list that looks like this: 40 5. Allows you to substitute one aspect for another. Now lets substitute 20 for the 5 in the variable c.
The new element will look like this: 40 h. You need to construct a new variable containing the entire list element, then use the new variable in the subst function. Constructs a new list with the new element placed at the begining. Assume variable c contains the following list: 40 5. Also, assume variable h contains the real number Therefore, car c is the new first element, followed by the value of h.
Thus it produces a new list d 40 In the list found in variable b and assigns the new list to b1. Takes an angle in radians and converts it into a string, using a specific format. Angtos has two arguments, the first controls the format and the second controls the precision.
This function returns the convertion of an integer to a real number. One can use either real or an integer. In other words, it is not used to assign a value to a variable as it is in some other programming languages. AutoLisp uses the setq function to perform this task. In AutoLisp, the equals character is used to test if items are equal, it does not make them equal.
This is very useful if we are trying to test certain conditions. For example, we can begin to construct tests with an outcome such as "if one thing is equal to another thing, do something". That's what conditionals are all about; they allow your program to make decisions. If a is equal to b , then b will be assigned the value 5. If it is not, then b will be assigned the value 6.
This function accepts any number of lists as arguments. It evaluates the first item in each list in order supplied until one of these items is a value other than nil. This function tests the response and returns 1 if it is "Y" or "y", and 0 if it is "N" or "n", and nil otherwise. A loop is necessary if you want to repeat a command. However, unless you have a way of controlling it, the program will run forever and hang you up.
A closing parenthesis closes the loop, and program will continue with the commands after this.
