This seems absolutly silly.

Why does this not work?
I'm trying to build a command to replace AutoCAD's "DI" command, to give distance and delta x, y, and z values in decimal and imperial, and keep the angles in XY plane and out of XY plane.
The error below has appeared randomly when AutoCAD 2011 is started. There was not an error of this sort, but it suddenly appeared and some of the LISP routines will no longer work.
*Invalid attempt to access
a compiled function definition. You may want to define it using defun-q:
#<SUBR @000000003f5fda98 S:: STARTUP>
I D/L a lisp file (setvars.lsp) that purports to give a list of system variables that match a short string entered in a dialog box.
Unfortunately, an error arises that says 'error : no function definition: STRNUM'
I've looked at the code and can't tell what the writer was hoping to achieve.
The specific section is as follows:
(if F1
(progn
(setq RL (read-line F1))
(while RL
(if (and (wcmatch (strcase RL) (strcase (strcat "*" DESCR1 "*")))
(wcmatch (strcase RL) (strcase (strcat "*" DESCR2 "*")))
[Code] .........
There is no other mention of STRNUM in the whole of the lisp.
There is an accompanying setvars.dat, wherein apparently, the writer compiled a data file of all the system variables in AutoCAD2008, each variable being followed by an '=' and then a description of the variable.
If necessary I can post the whole lisp and dat file, but was hoping to discover the intention from the above extract and therfore where I might work out an alternative to this line.
Looking to turn a string to a real? If so, why are there two 'arguments' following the 'function' STRNUM?
simple example code how can i set my lisp function to radio button ?
i found simple dcl - lisp codes , there is possibility for calling simple cad commands , but this is different about call lisp with buttons
which code i have to change and how for set my lisp on radio buttons ..
here is the sample codes ...
SAMPLE1 : dialog { label = "Sample Dialog Box Routine - Part 1"; : column { : boxed_column { : button { key = "but1"; label = "Button 1";

I want to define en expiration date in registry, after that date the some LISP programs does not allow to run. I think that suitable commands are SetEnv and GetEnv.
define a ExpDt variable that contains Expiry Date as a string. And add some statements inside of the LISP program to call this variable and check it with today's date.
I should define once time in autocad:
(setenv "expdt" "130101"); YYMMDD date for validation period (2013.01.01)
and check this every time that a lisp program should be execeute:
(getenv "expdt") ; if today's date(with YYMMDD format) ">" expdt then lisp program doen not allow to run and should be halted.
for e.g. on 2013.02.28: "130228" > "130101" ==> so the lisp function should be halted and will not work!
(without any alert or message)
a sample list function: (how can implement on this lisp function?)
(defun c:3()
(setq w t)
(while w
(setq a (getpoint "
pick point:"))
(setq p1 (list (- (car a) 0.5)(- (cadr a) 0.5)))
(setq p2 (list (+(car a) 0.5)(+(cadr a) 0.5)))
(command "erase" "w" p1 p2 "")
(command "INSERT" "*3" a "" "" "0")
)
(if (= a nil)(setq w nil))
)
In the foreach function can you use math like (foreach pt1 (add 1) so that foreach one you pick it adds one the next one will be named pt2 then pt3 and so on.

I prepared a code to calculate number of days between two date.
I want to know how can I define negligible arguments for my lisp routins. It means if I omitted the arguments, lisp code can handle it without any errors ("; error: too few arguments")
In this case, my program defined as: (TotalDays 1st_date 2nd_date)
(TotalDays 1978 03 21 2013 06 25)
and I want to have flexibility: if I use this routine as (TotalDays 1978 03 21), the program should substitute today's date with second date.
I know if I put "nil" instead of date for 2nd_date, It will not be an error, because:
(if (and y2 m2 d2) (setq n2 (GetJDN y2 m2 d2))(setq n2 (fix (getvar "DATE"))))
but that's not my favourite!, how can I omitted 2nd_date completely? as (TotalDays 1978 03 21)
Here is my lisp

I was able to find/update a LISP program that returns the dynamic block to its original state, overriding the anonymous name and make the actual block name the effective name. I am in the process of manipulating the LISP program so I can select multiple blocks rather than one at a time.
(defun CYMEFFEC ()(vl-load-com) (setq obj (vlax-ename->vla-object (car (entsel "Select blocks: ")))) (vlax-put obj 'Name (vlax-get obj 'Effectivename)))

I have already searched the web and this newsgroup but have not found the solution.
I have a simple lisp function to add a scale axis to a drawing by calling a script, renamed the drawing by appending "withScale" to the file name, and then closing the file. I placed a call to the function in the acad.lsp file in the startup suite. The idea was to batch process all files by simply opening them. Upon open the startup acad.lsp file runs, which calls my lisp function, which in turn calls the scale script. It should then execute the renaming, saving, and closing commands. The problem is that it is calling the script fine and renaming the file, but it does not save the changes before closing. Here is the lisp function
(defun saveScale(); (command "-purge" "all" "" "n")(if (findfile "C:/Users/Russell/Desktop/TreeFiles/Automation/Scale&Key.scr")(command "_script" "C:/Users/Russell/Desktop/TreeFiles/Automation/Scale&Key.scr")); end if (command "_.zoom" "e") (command "_saveas" "2013" (strcat (getvar "dwgprefix") (vl-filename-base (getvar "dwgname")) "withScale.dwg")) (command "close") ) (saveScale)
Apparently you cannont run any lisp commands after calling a script, however the renaming still follows through.
I've attached the script file as well. (I couldn't attach .scr format so you may need to rename it).
I have a list function that asks for the user to pick points when it is run. It looks something like this (foo arg1 arg2) When invoked it asks the user to pick points and press enter when done It.
Instead of getting the points from the user i want to pass it a list of pre-defined points. The code cannot be changed so I must use it as is.Is this possible, if so how can it be done?
I've got a subroutine that gets the centroid of a closed polygon (lwpoly). It appears to fail if the polygon has any zero length line segments. I've added a trap that catches the error and "highlights" the offending polygon, but it stops there and does not return to the main function that called the subroutine. Is there a way to get back to the main function from the trap?
Here's the subroutine (original function by _gile (Autodesk LISP Forum 9-18-2006):
(defun return-centroid (lwpoly space / obj Region Centroid)
(setq *error* trap1)
(setq obj (vlax-ename->vla-object lwpoly))
(setq Region (vlax-invoke space 'addRegion (list obj)))
(setq Centroid (trans (vlax-get (car Region) 'Centroid) 1 0))
(vla-delete (car Region))

I am trying to customize AutoCAd for a special domain where attribute values need to have a type. I can have a clean integrated solution by manipulating the acad.dcl or base.dcl .I am using AutoCAD 2012 . I want to extend the " define attribute" and "edit attribute" dialog boxes to promt the user for a value type when they define an attribute .I can't find the definition for these dialog boxes in acad/ base dcl files. Ideally I want to add another tile definition to these dialog boxes .If that is not possible atleast spawn a different dialog box from the "define attribute " dialog box that will collect the value type from the user.

So far what I have found in this forum and TheSwamp the best way is to use DeepClone of BlockTableRecord but the objects in original BlockTableRecord need to be DeepCloneObjectes into new block. Otherwise new block will have all objects with ObjectId from old BlockTabkeRecord.
There are times that I have a really long curb polyline that has both line and arc segments. I wish to pick two points along that polyline and have it give me the distance between those two points along the path of the polyline.

I would like to eliminate a mouse click in my program. I use getstring to allow the user to either enter in an integer or a distance used for labeling in a drawing, but I could eliminate the need for the user to then click an option that completes the label if I only knew how to determine if the entry is an integer (such as 5 or 15) or a distance (such as 24" or 36").

Let's say I have a 3D polyline, which I turn into a spline. I then want to determine how closely the original polyline and spline follow each other. How I can check this programmatically? The concern is to find the maximum deviation and its location.
Howto be able to run the check on other types of objects as well: arc, polylines etc.
I would like to write some sort of AutoLISP program to evenly space objects across a given distance. I have attached a .pdf file showing what exactly I mean.
I would like the program to enable me to either enter or measure (via the selection of two points) the "z" distance, to enter or measure the "y" distance, and to enter the number of objects, "n". I would then like the program to evenly space "n" objects across the "z" distance.
A program like this is, I have to be honest and say, way beyond my current capabilities.
Perhaps some initial guidance to get me going?
I have double line pipe drawings but i have to change distances between of this lines in entire drawing and i was thinking that maybe there is a lisp code which can create new double line according to my specify dimensions ...
example :
Distance between lines : 100 mm
------------------------
------------------------
here is what i want to do :
1. select double line
2. specify new distance ( for example 200 mm)
3. lisp will create center line middle of the selected lines ( maybe it can ask me that this center line will be permanently or not )
4. lisp will create new double line from this centerline according to my specific distance
5. new double line layers will be the same with selected old double line
and this lisp has to work for double arc or quarter circles too.
Is there any way to include a trig function in the displacement distance?

I'm trying to be able to have a function run another function with the secondary function being passed as an argument to the first. I'm trying to create a recursive function and the recursive part works great. I just need to be able to have the recursive function run other functions to actually do stuff.
Here is something I found that should do what I need, mainly run a function from a function name in a variable.
Sub test() Dim ftnName As String Dim argument As String Dim result As String ftnName = "myFunction" argument = "cat" result = Application.Run(ftnName, argument) MsgBox resultEnd SubFunction myFunction(inString As String) As String myFunction = inString & " has " & Len(inString) & " letters."End Function
However I get the error "object required" on the "result = Application.Run(ftnName, argument)" line. So I'm guessing the Inventor VBA doesn't like this method of doing this. I'm just hoping there is a way to do this or this function will be useless or reduced to hardcoding functions which still defeats the purpose.
i'm trying to create a LispFunction in vb.net in visual studio 2010 (tried both .net 3.5 and .net 4.0) and it's like autocad is just ignoring them. is there a setting or something to disable .net LispFunctions from being loaded?
