This example defines a point located 5 units in the X direction and 1 unit in
the Y direction from the point stored in AutoLISP variable A.
A+[5,1]
If you enter an AutoLISP variable with a name containing a character with
special meaning in CAL, such as +, -, *, or /, enclose the variable name in
apostrophes ('), for example:
'number-of-holes'
Assigning Values to AutoLISP Variables
To assign a value to an AutoLISP variable, precede the arithmetic expression
with the variable name and the equal sign (=). Later, you can use the value of
this variable for other calculations.
This example saves the values of two expressions in AutoLISP variables P1 and
R1.
Command: cal
>> Expression: P1=cen+[1,0]
>> Select entity for CEN snap: Select a circle or an arc
Command: cal
>> Expression: R1=dist(end,end)/3
>> Select entity for END snap: Select an object with an endpoint
This example uses the values of variables P1 and R1:
Command: circle
Specify center point for circle or [3P/2P/Ttr (tangent tangent radius)]: 'cal
>> Expression: P1+[0,1]
Specify radius of circle or [Diameter] <last>: 'cal
>> Expression: R1+0.5
