AutoCAD Visual LISP / AutoLISP :: Checking For Existence Of Drive Using Code Not Working?
May 2, 2013
I'm trying to check for the existence of a drive using lisp, then if not found perform a task (represented in my below example by the alert)
(if (vl-file-directory-p "C: en") T)(alert "exists"))
I know it doesn't work because if I change the T to nil as demonstrated bellow I should invoke the opposite reaction from autocad but instead I get the exact same outcome which is an alert telling me the file exists?
(if (vl-file-directory-p "C: en") nil)(alert "exists"))

I have a specific need to determine if an entity is existing or not so that I can either make changes to or create the entity. I'm trying to do this while referring to the entity by it's handle. Below is my code this far but it doesn't work.
(IF (AND (SETQ HNDL (VLAX-LDATA-GET "TB" (STRCAT PLN "PLAN"))) (NOT (VLAX-ERASED-P (VLAX-ENAME->VLA-OBJECT (HANDENT HNDL)))) ) (PROGN ;;| DO SOMETHING WITH THE EXISTING ENTITY ) (PROGN ;;| MAKE THE ENTITY
(vlax-ldata-put "TB" (strcat PLN "PLAN") (CDR (ASSOC 5 (entget (entlast))))) ))
I ran the program and the handle was stored, then I deleted the entity and ran the code again and this is the error I get:
; error: unable to get ObjectID: nil
This VLISP stuff sometime has unpredictable hoops to jump through first, so I wondering if this is the case here.

I know to get the spacial filter on an xref to get the clip verticies, but not how to tell if its an invert xclip.
Even the arx guys seem to have difficulty with this. How to do it with lisp, com, or arx code?

I need a lisp code to convert all Lines, Polylines, Arcs and Splines to Polylines with 0.4 width.
I prepare this:
(defun c:CH2pl ( / SS);changes all lines, plines, arcs and splines to POLYLINE with 0.4 width(if (setq SS (ssget "_X" '((0 . "LINE"))))(command "_.pedit" "m" SS "" "Y" "w" 0.4 ""))(if (setq SS (ssget "_X" '((0 . "*POLYLINE"))))(command "_.pedit" "m" SS "" "w" 0.4 ""))(if (setq SS (ssget "_X" '((0 . "ARC"))))(command "_.pedit" "m" SS "" "Y" "w" 0.4 ""))(if (setq SS (ssget "_X" '((0 . "SPLINE"))))(command "_.pedit" "m" SS "" "Y" 10 "w" 0.4 "")))
But I want pure lisp code in a professional way!

Modify the attached lisp I found in this forum to work using a different hatch pattern, scale and angle. The new hatch should be in default Autocad "LINE" pattern and angle set to 90 degrees (vertical). If possible, I would like the angle and scale to be editable. Find attached Multi_Hatch-45 code posted by CADaStroumph in 2008.

This lsp was passed on to me from a colleague but he doesn't know where he got it. It does a useful procedure of placing each xref, residing in the drawing, to a unique layer. The layer name is derived from the xref name. I would like to edit this to take only part of the xref name. This system I work with requires all files to have the job number as a prefix eg LE1399901_Contours.dwg, so the xref name would be LE1299901_Contours by default. I want to remove the first 10 characters to be left with "X_Xref-Contours" layer name using this code.
(defun dxf (i a) (cdr (assoc i a)))
(defun c:lxr ( / ss cnt xrs en ed bn xp xbn )
(setq ss (ssget "x" '((0 . "INSERT"))))
(setq cnt 0)

I have this code to draw grid lines within a rectangle:
;Variable settings(defun var_set () (setq *var_lst* '("cmdecho" "osmode" "expert" "plinewid" "dynmode") *var_usr* (mapcar 'getvar *var_lst*)) (mapcar 'setvar *var_lst* '(0 0 2 0 0)) (vl-load-com))(defun var_reset ()(mapcar 'setvar *var_lst* *var_usr*)) (defun *error* (msg) (if (not (member msg '("console break" "Function cancelled" "quit / exit abort" "" nil)) ) (princ (strcat "
Error: " msg)) ) (and ;(vl-bt) (var_reset) ) (princ) ) (defun string-list (data) ;by lee-mac @theswamp (if (vl-string-search "@" [code].........
The above gets me the grid lines; but I have a block inserted at both ends of the grid line; how do I get the selection of those entities (selection set "frame") after each array?
or I would need to map a point list and draw each grid individually how do I go about that?
Attached is the sample of the output I'd like to achieve using LISP.

The code removes prefixes bind ($ 0 $), renaming layers, blocks, dimension styles, but some objects do not change the name as linetypes, text styles and duplicate names.If I have an existing name, I want to change the name with a (2) at the end.Example.
Layer: FloorLevel$0$Door90
If the layer "Door90" is existing, is renamed to "Door90 (2)"
(defun c:delprefixe(/ ActDoc Name NewName)(vl-load-com)(defun RemoveBindPrefix (String / Pos LastPos)(if (setq Pos (vl-string-search "$" String))(progn(setq LastPos Pos)(while (setq Pos (vl-string-search "$" String (1+ Pos)))(setq LastPos Pos))(substr String (+ 2 LastPos)))String));

I have lisp code, which count total length, but I need that it count and multiply by constant which I choose manual (such as in example, total lines yellow length * y + total blue lines * x = ... , example 50*2 + 60 * 3=280),
remember the another code, such as I have d200 with total l=1000 and d250 with total l=1500, i need to count total cost such as 1000*y+1500*x
one think, diameters numbers is not only 1 or 2, it can be many different diameters.

I recently upgraded to a new PC.
We get a lot of files from customers where there are multiple drawing borders all in model space.
Sometimes as many as 150-200 borders in one file that we need to print for the shop floor.
Years ago, I wrote a LISP routine that prompts for printer settings (Fit or To scale, etc.) and then prompts for
2 corners of each border and then writes a script file and launches it to batch plot each drawing.
My thinking was that I had to manually pick each drawing anyway, this LISP routine saved me from having to issue the plot command over and over.
Anyway, since my PC upgrade, the LISP routine fails.
There is a line of code that answers the plot prompt for output device name where I have the same printer as always.
When the script runs up to that line, AutoCAD tells me that printer is "not found".
So then it keeps reading the rest of the script lines which answer other plot prompts and repeatedly says "device not found".
If I manually print, I can choose the same print settings in the dialog box that the script file has and it can "find" that same device.
Why I can print manually but the LISP/script file gives me a "not found" error.
BTW, when I upgraded my PC, I also upgraded AutoCAD from 2012 to 2013..

I upgrading all our lisp routines to 2013. I have a routing that modifies a block attribute. Then ENTMOD returns with the proper information. ENTUPD reurns the same enity name. The block never changes. The same routine woks in 2010.

I know how to retrieve the entity information from the block, but can't figure out how to write the loop statement to loop, look for first attribute, assign to a variable, goto next attribute, assign to different variable, etc., etc...
In my research, most programs I've seen it execute the loop, assign to a variable, then print/put that data somewhere, loop again and utilize the same variable to print/put the next data somewhere.
I would like each attribute within a block to be assigned a separate variable.

The good news is that, if I were righting a routine that locks up AutoCAD, I'm finished. The bad news is that I'm not.
The code below is the portion of a routine where I have the user select 2 points and then pass those points to the Zoom command and the M2P osnap. The problem is that, when the Mid Between 2 Points osnap tries to use the first point, it returnns an "Invalid point" message, enters a loop and locks ACAD.
(defun C:ZC ()
(setq PointOne (getpoint "First point of M2P "))
(setq PointTwo (getpoint "Second point of M2P "))

Should SETENV/GETENV be writing/reading to and from the System Registry?
After installing ACAD 2013 as a trail this now seems to be the behaviour, only found it when GETENV calls started to fail. This has also affected previous versions installed on the same workstations.

I have a macro that i have been using in autocad 2012 for a simple copy & rotate command as follows
^C^C_select;auto;\_copy;p;;0,0;0,0;_move;p;;\_rotate;p;;\redraw
For some reason it now does not work in 2013 the macro exits after the copy part of the macro is finished & fails to let you rotate the copied object.

I am trying to make a script file to open a drawing and run a lisp routine. They both work independently just fine, the script file will open the all of the files fine... and the lisp is in the startup suite and works in all the files. But when I tell the script file to open the first drawing then run the lisp it hangs trying to open the next file after running the lisp. I have Filedia set to 0, but the message I get when it goes to open the next is "No canvas exists. click New Canvas." (And on top of that... Filedia even set back to 1 still does not display the Dialog box anymore, I have to shut down AutoCAD 2012 and start again then it works.) I Have tried several ways, Opening one at a time then run lisp, and open all files first and then try to run lisp (that closes the file after running) and try and run it again in the next... It will only run the lisp one time and then locks up from there.

Is there a lisp that will allow me to do a continuous dimension, but will alternate the dimension position from low, high, low and high? If there is no lisp already created, how to create one?
See Continuous dimension attachment for example.
I work at a glass and glazing company and this is how we dimension mullion width and DLO. See typical window dimensioning attachment for window elevation with dimensions.
