1. initget: This function initializes keywords or input filters.
(initget [flags] [keywords])
Flags: This is control flag for next input function.
Ex. (initget 7)
(getint “\nOnly Integer value ”)
2. getreal : This function ask for user input of real number and returns real number
(getreal [prompt])
Ex. (getreal “Width:”)
Width:» 2.5
2.5
3.getstring: This function prompts user to input text string.
(getstring [flag] [prompt])
Ex. (getstring T “You can enter words with spaces”)
(getstring “one Word only”)
4. getpoint: This function asks you to enter a point .
(getpoint [point] [prompt])
Ex. (getpoint)
Now click in GA or input point to get point : lets say 0,0
It will return as (0.0 0.0 0.0)
(getpoint “Click in GA”)
Click in GA» (Click in GA)
(5.89125841 1.41504584 0.0)
5. getcorner: This function asks user to enter opposite corner of rectangle.
(getcorner point [prompt])
Ex. (getcorner ‘(0 0) “Specify corner point: “)
Specify corner point: » (Click in GA or input corner point for rectangle.)
6. getdist: This function asks for user input for two points to return distance between them.
(getdist [point] [prompt])
Ex. (getdist ‘(0 0) “Specify Second point: “)
Specify Second point: » 5,0
5.0
7. getangle: This function asks user to enter angle , Here point argument is for base point to calculate angle, if point is not specified then user have to input both the points to calculate angle between them . Angle increases in counter clockwise direction.
(getangle [point] [prompt])
Ex. (getangle ‘(0 0) “Specify second point”)
Specify second point»
The calculated angle is return in Radians .
Related functions: getorient .
Related system variables: ANGBASE, ANGDIR , AUINTS
8.getorient: This function is same as getangle
(getorient [point] [prompt])
9. getkword: This is important function to ask user to input any keyword for options
The keyword options are set in initget function (See point 1 above)
Ex. (initget 257 “Yes NO”)
nil
: (getkword “Copy Entities ? (Y/NO): “)
Options: Yes, NO or
Copy Entities ? (Y/NO): » y
Yes
10. getint: This function asks user to specify any integer (data type ) value and returns the specified value.
(getint [prompt])
(getint “Specify an integer value: “)
Specify an integer value: » 5.5
Requires an integer value.
Specify an integer value: » 5
