You can do exactly the same with them - get and set them - but using vla commands instead of dxf group ones like entmod and entmake. ![]() (setq e1 (car (entsel)))(foreach i (entget e1 '("*"))(print i))(textscr)(princ))Īnd this is a good one too, for listing "VBA" style properties. (DEFUN C:GET () (PRINC "\nPrint dxf groups") I would recommend you also have this "get" function handy, for listing the dxf pairs of any entity: Note that I use tabs, so you should set the spacing to 2, or replace with 2 spaces to get looking decent. Custom component First use entget to collect data of an existing entity, and it shows me this list: ( (-1. Ok, the formatting in this forum kills all indentation, look at attached lisp in following post. Autolisp entmake missing parameter Ask Question Asked 10 months ago Modified 9 months ago Viewed 37 times 1 I'm using Autolisp to create an entity (a plugin component). entmake (AutoLISP) Creates a new entity in the drawing (entmake elist ) The entmake function can define both graphical and nongraphical entities. (entmod (subst (cons 62 lname)(assoc 62 elist) elist)) entmod-entupd is way faster than chprop (defun c:byl (/ SS COLOR ELIST ENAME INDEX LNAME) I just updated this compared to original post. I am assuming index color here, say if you are dealing with trucolor. Thereis a trick, in that if a entity is bylayer in color, it has no dxf color property - group 62 It's just that in ACad it's generally easier to start such a thing in AutoLisp (not as much preliminary work and learning to do as you'd need when making your tools in C++/C#).You will loop through the entity names and change each as needed. as an ObjectARX extension written in C++, or a DotNet assembly written in C#, or some older stuff as VBA macros. It may equally be written in something else, e.g. like Lee Mac's Increment Suite, or the AutoIncr tool in one of my old tools: Caddons ). That example may very well be an AutoLisp tool someone wrote (i.e. And yes, alanjts correct in saying read the help. This is usually needed when you make non-graphical entities such as dictionary records. EntmakeX does not assign the new entity to an owner, you have to do it afterwards. Others (both older and more recent) include: Common Lisp / Scheme / Clojure / Racket / Julia / etc. Another difference is entmake assigns the entity to an owner, usually the Model Space / Paper Space block. Since then many different implementations were created, AutoLisp derived from one called XLisp which was made in the mid 70s. You get other Lisps as well (though not of much use inside of ACad), LISP was originally one of the very first programming languages, in fact it's the 2nd high-level language just after Fortran (originally made in 1958 ). This works as an interpreted scripting language (much like JavaScript works inside of web pages). Another difference is entmake assigns the entity to an owner, usually the Model Space / Paper Space block. Inside AutoCAD there's a variant of LISP called AutoLisp. Was what I witnessed a lisp?LISP is a programming language. ![]() The number size varied to paper scale size. Years ago I witnessed a person working on autocad and he was placing numbers within a circle just by clicking the mouse. You may do it in the native AutoLISP way, with ENTGET, ENTMAKE, SUBST etc., or you may have learned to convert it to a Visual LISP object with VLAX-ENAME>VLA-OBJECT, access its properties, and use its methods, such as GET and PUT. Please let me know and move if it needs to be. You’re good at getting entities, so you’re probably good at manipulating them as well. (setq chrnum (ascii (substr ptnum 1 1))) 1st character is number In this course, Josh Modglin walks through. Hatch patterns, block explorer palette are some of advanced features available that are. (setq ptnum (getstring "\nEnter Pt Number or alpha")) Due to its relative simplicity and historical integration within the AutoCAD environment, LISP is a natural first programming language for CAD managers. (defun C:bub (/ ptnum ptnumb pt pt2 oldsnap chrnum sc curspace) (mapcar '(lambda (pt) (cons 10 pt)) vertexList)
