Create a multi selection input.

Hello everyone.

Since I am new to autolisp, please bare with me.

I need to do the following:

Create some choices (big|med|small) and have the user select his choice with the mouse which then will be written in a variable.

Any suggestions?

Look into the getkword & initget AutoLISP functions.

My tutorial here may also be of interest.

If you want mouse pick then you will need a dialouge box, a couple of choices do you want a square with a label or a "radio button" with label beside ? please advise There are other methods such as cheat way using a yes no cancel box

 (SETQ reply (ACET-UI-MESSAGE "Big Med Small Choose Button "
                             "Perifanos Dialog"
