Select the line and selected point at once

I can select the line Usins entsel command.

How can I find out the selected point (coordinates) with same time.

ENTSEL fuction will return a list containing the selected entity and the coordinates of the point picked by user:

(cadr (entsel))

Alternatively check SSGET and SSNAMEX functions which will give you more information on user's selection action.

(ssnamex (ssget))

Thanks a lot for your quick reply.

I used your first option.

But results is not 100% crrect.

I thing the point is someware inside the pick box. not exactlly on the object.

Try use this pick point / coordinates (snap endpoint) of entity

That't true, it will return the coordinates of picked point's (that't it, the center of pickbox); in most cases this isn't a point on selected entity. To project it on the entity please check the VLAX-CURVE-GETCLOSESTPOINTTO function.

Please pay attention that for most entities this will return the same as ENTSEL.
