Feb 22, 2012
how to append I’m assuming its not write-line but append line. And also I’m having trouble recording the date variable… I keep getting error bad argument type stringp nil
; Appends usage count by DATE long variable...(setq g(open "C:/ICT/AutoCAD_Architecture_suite_2012/CUSTOM/WOOD Clones/PEN/USSAGELOG.PEN" "w"))(setq MYDATE DATE)(write-line MYDATE g); AS ABSOLUTE LAST WE NEED TO CLOSE THE TEXTFILE...(close g)
I have the following code snippet I’m trying to append the file named USAGELOG.TXT to record the date of executions

I'm looking for a way to find out what all plot styles are set in drawings in a sheet set.
We are transitioning from color based pen settings to style based and would like to be able to export a log that shows the variable PSTYLEMODE for each drawing in a sheet set. I plan on using ScriptPro to run it on the full sheet set.

I have attached 2 lisp files. datblkx5 makes a block of selection, inserts the block with a 5x distortion, explodes it, and corrects the text for width factor and text height. This one works fine.
I wanted to add the feature of scaling my selection with a user input value. This is the lisp datblkxxx. This one doesn't work. (that is it doesn't correct the text for width factor). I can't figure it out.

I've been trying to append a user input by adding this text "ABC" to the front of it. How can I do that?
(setq NUMX (getstring "
Please specify NUMBER:")); INPUT NUMBER 123 HERE
(SETQ NUMXX (append '(ABC) NUMX))
So that NUMXX now equals ABC123.

I am in the process of creating 2 lisp routines, one that loads Support file search paths on the network and one that adds support file search path locally. Each routine will be run depending on the ability of ACAD to find a file on the server. I noticed that when I add the new directories the default AutoCAD folders get replaced. I researched this and found that using the SETENV and ACAD I can include the default support paths.
The issue I am running into is that not all default folders are being added to AutoCAD when I used the ACAD variable. A plugin folder under Program Data is listed in the original install, but it is not listed when I add my directories and used the ACAD variable to add the default directories. The same thing happens when raster design is installed. The help folder and the install directory for raster are not carried over when using the ACAD variable.
I am attaching the coding for the lisp routine adding server paths. Is there some syntax I can add to tell it to append to the list instead of replacing the SFSP list?
(vl-load-com)
(setq files (vla-get-files
(vla-get-preferences (vlax-get-acad-object))
)
)
(setq SERVNM (getenv "servername"))
(setq SLSERV (STRCAT "\\" SERVNM))

I am trying to change the current TARGET variable to 0,0,0. If the variable is not changed is causes problems with plotting. I have the VBA that will change the TARGET variable. VBA works no problems. I am wanting to replicate in LISP because I do not want to have to convert to .NET and do not want to make sure the user has the VBA loded on thier system. Here is what have so far.
;;;Get active viewport
(setq avp (vla-get-ActiveViewport (vla-get-ActiveDocument (vlax-get-acad-object))))
;;;Get current TARGET variable
(setq CTarget(vla-get-Target avp))
Here is the problem. Is changing or putting the vaiable.I have tried
(vla-put-Target avp (vlax-3D-point '(0.0 0.0 0.0)))
and
(vla-put-Target avp (vlax-make-variant (vlax-3D-point '(0.0 0.0 0.0))(vlax-variant-type CTarget)))
They either error out or nil with no change. I have even tried to locate it in the Dictionaries.

There is a command in autocad that will get a Bounded Volume from a closed polyline and a volume surface (command "AeccReportSurfBoundedVolume"). It reports the results to the screen. How to get the "Net Volume" results in to a variable using Lisp?
Maybe a lisp routine that gets information from the text screen. That would not be ideal but I could work with that.

I've created a list and want to subtract all the values within it from another variable, and assign it to a new variable. How do I do it?
Basically, I ask for ground level (assigned to variable G1), and then any number of depths beneath that (assign to list LVLLIST), and I want to return the value of the bottom point. So it's all the values in LVLLIST added together and subtracted from G1. And assign it to a new variable BASE.
For example,
G1 = 650.00
LVLLIST = (1.23 23.26 0.13 50.23)
(setq BASE (- G1 LVLLLIST))

How to write some code which could create variable names like var1, var2, var3, etc. I need to do this because I have a large number to create and the actual number is variable and unknown.
Instead of manually writing a large number of line like
(setq var1 value1)
(setq var2 value2) etc
I used to be able to put 1 line in a loop to create and assign a large number of variables. I remember that it involved the use of the set (not setq) and read functions.

Is there anyway to program variable names?
What I was thinking of was in a loop some times I need multiple sets of similar variables but am not sure how many sets I am going to need. I would like to be able to increment the variable names each time the loop runs.

A2008. Is there a setvar, setenv, registry entry etc. that can be used to change the scale of Multileaders with annotative off to have the same effect that DIMSCALE has on Q leaders? I want to have a single scale-independent Multileader style and modify it on the fly along with DIMSCALE and LTSCALE. I'd use Qleader but UCS's do odd things to text position and orientation.

I would like to use a string as a variable if this is possible. I've got:
new-pl-lay (as a variable that holds layer name "UGL_PL_NEW")
first-cable (as a string that holds "new-pl-lay")
I'd like set the current layer to "UGL_PL_NEW" by using the first-cable string.
Something like:
(command "_.layer" "m" (read first-cable) "")

how to write a lisp command, or function, that will save my newly created drawing with a file name is that is called up from a variable.
For example:
(setq filename variable)
(command "saveas" "r14" "filename")
and i would want the outcome to be: variable.dwg, rather than filename.dwg. I have tried numerous different ways of doing this with command prompt and cant seem to get anything to stick. Everything that works just creates a file named "filename.dwg", which is not what i want to do.

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))
)

How do I check, with LISP, if a System Variable is read only? In particular ANNOTATIVEDWG. This one is read/write when there are no annotative objects in a drawing, but read-only if there are.

I would like to create a lisp that does the following:
Update a titleblock attribute with a $variable.
The titleblockname is variable / not static.
The attribute is not variable / Static, DW_SCALE
The titleblock is always places on the same layer, BL$4----
The (custom)-plotscale is stored in the $var "gvpsc".
I've tried to ajust the following lisp code. But I couldn't extract the part I need.
The problem is, the code checks all the layouts and updates all the titlblocks one by one.
Truely a good code.
The only problem is, I don't have multiple layouts and I have a variable titleblock name.
Here is to code i've tried to convert to something I could use.
(defun C:UPD-DPC () (setvar "cmdecho" 0) (setq blkname "DPC-STEMPEL");(getstring "
Enter the name of block to update: ")) (setq att1 "DW_DATE");(strcase(getstring "
Enter the name of the attribute to change: "))) (setq newatt (strcase(getstring "

I have this small lisp routine:
(defun c:1p nil
(command "_.-plot" "yes" "" "controls 11x17" "Ledger (11 x 17)" "inches" "LANDSCAPE" "NO" "view" "01" "FIT" "CENTER" "YES" "newpap2.ctb" "YES" "As" "NO" "NO" "yes" )
(princ)
)
I want to use it to plot different views which I will append to the command when it is called from within AutoCAD.This code will, of course, print view one.Currently my worst case is 25 views and, for that situation, I have simply repeated this code 25 times with a different function name an view number for each view. Eventually I would like to make a dialog box that would allow me to select with checkboxes (toggles) the views to print and with a button to print all.
For example, if I wanted to plot view 25, after I had loaded this lisp routine I would enter, on the command line in AutoCAD, the function name ("pp" perhaps?) followed by some variable (in this case 25, but could be any view name. ie. 01, elev, detail) and the view name would be inserted at the appropriate place.

I am using a variable that is being called up from a .csv file for a file name. By default this variable automatically includes a comma due to it being called from a .csv.
How to remove a character ( , ) from a variable? I'm not sure if this is along the right line or not, but i used the READ function to read the variable as a string (i think thats how it works?).
