gioxon Posted July 3, 2014 Share Posted July 3, 2014 Hello, I am working on a tunnel alignment. I have to draw multiple closed 3d polylines from AutoCAD Points (which form the tunnel sections from the excavation). I use the 3POLY command and then the option "PN. Is it possible to write a script (or a lisp routine) that repeats this process? For example, I wrote this script 3POLY 'PN 1-10,1 (1 row blank) 3POLY 'PN 11-20,11 It draws the first closed 3dpoly (from point numbers 1 to 10 and closes to 1) but it not continues to second 3poly. Thank you in advance Quote Link to comment Share on other sites More sharing options...
BIGAL Posted July 4, 2014 Share Posted July 4, 2014 I get unknown command for 3poly it may be a lisp etc then task can be done differently, other way is dump pts into excel and make a script of the points to be connected using 3dpoly x,y,z x,y,z etc. Did you mean 3dpoly ?

gioxon Posted July 4, 2014 Author Share Posted July 4, 2014 Did you mean 3dpoly ? Bigal thank you for your reply, I'm sorry for the inconvenience. You are right, I mean 3dpoly command. I've already tried the solution you suggest (i made a script with the points like the image) but it is no convenient for me. I have already imported all the points from a txt file. The most important aspect of the solution I seek is to draw these 3d polylines using the point numbers and not by using coordinates. Quote Link to comment Share on other sites More sharing options...
BIGAL Posted July 5, 2014 Share Posted July 5, 2014 I had a Google your close it is probably your script, I would still look at excel and write a macro to work out the start and end of point groups. Will see if I can do. not tested 3dpoly 'pn 1-35 C 3dpoly 'pn 36-72 C Quote Link to comment Share on other sites More sharing options...
