Join Josh Modglin for an in-depth discussion in this video Function: getpoint, part of Learning AutoLISP & Visual LISP.
- [Instructor] Another useful get data function…from LSP is the getpoint function.…The getpoint LSP function will return…a list containing three numbers.…The three numbers represent the X, the Y and the Z…where the user picked when he was prompted.…Let's go ahead and get a point from a user.…In this case, the user would be me.…GETPOINT, and we are simply going to provide the prompt.…Specify a point in space will be our prompt.…
We could, of course, type in any prompt there,…and we'll inspect this code.…It says, Specify a point in space.…Now, if I press Enter and don't specify,…the result is simply nil.…But if I do go back, and let's inspect again,…and pick a point in space, it returns a list…with an X, a Y and a Z, showing the coordinates…where I picked.…
