OSNAP command in Autolisp

_mac — 2010-07-27 10:18:32

[QUOTE=_mac] I have a similar problem but with the osnap "per", can someone confirm this. (command "line" p1) (setq p2 (osnap (getpoint "'nPick point: ") "per")) These lines worked in ACAD but not in ZWCAD. Anyone from zwcad care to comment on this?

Ok thanks all, do I assume then that the osnap problem has been fixed and will work correctly in (_VERNUM = "2010.04.30(14725)") ?? It is now middle May, has this version been released yet ? Thanks ps. Yes , Eric, my ID is a reference to the asign function in LISP, namely setq. I think it appropriate for postings where LISP is discussed. Been programming LISP since 1980....

[QUOTE=Andrea]tested.... Osnap in version 2010 is not working...but it work on 2010 beta. just be sure to put the Underscore on the snap settings eg: "_end" hi,Andrea, thank you for you sharing~~ have a nice day Eric

hi,setq, your id is very interesting, is it a assignment function ? to be frankly ,i know a little about programme ,but i just know little about lisp . i tried (setq p1 (osnap (getpoint "'Pick intersection: ") "int")) in zwcad 2010 (_VERNUM = "2010.04.30(14725)") ,it works well ,returns the coordinates of the intersection i osnap. If no intersection is found, it will return NIL. BTW,zwcad2010((_VERNUM = "2010.04.30(14725)")) will be released in MAY. if the problem still exist , would you please kindly send your the problem to tech@zwcad.com via email and tell me the vernum of zwcad you are using . It is better to make a movie to record the operations you have done before the problem occured. In this case, we could verify the problem easily. After receiving your email, we will try to find a solution for the problem as soon as possible. Thanks in advance. have a nice day and wish to learn more from you ~~

The following line of lisp code should return point p1 only if an intersection is found. If no intersection is found, it will return NIL. (setq p1 (osnap (getpoint "'Pick intersection: ") "int")) It works perfectly in 2009i, but crashes in 2010. If the safety feature is omitted, namely: (setq p1 (getpoint "'Pick point: ") ) it works in 2010, but it will now snap onto anything, even a void.
