Create spline

[hunszab]

Hi all!

How can I create a spline from n points?
(command "spline" point1 point2 pointi ... pointn) works, but I have to specify the start and end tangent. I want to do it automaticly i.e. 0, 0.
How can I do that?

That'd be better if I could make it with the entmake command!

Thanks any help!

I have moved your question to its own thread, please start a new thread for each new question.

To get default tangents just use "" (equivalent to <ENTER>) – a series of 3 "" at the end of the function call will do the job (one to end points input and the folowing two to accept default tangents:

(command "_spline" point1 point2 pointi ... pointn "" "" "")

PS. Maybe the best location for this thread is under AutoLISP, Visual LISP & DCL sub-forum.

Thanks a lot!

And I modify my problem: I have a list that contains n points, and I want to make spline!

[MSasu]

For this case can use the below approach:

(command "_SPLINE")   ;start command function
(foreach thePoint MyPointsList
 (command thePoint)   ;parse points list and feed the SPLINE command
)
(command "" "" "")    ;close points input and accept default tangents
