AutoCAD .NET :: How Lisp Function Interpret Lists Passed In
Jun 20, 2012
I had thought this was fixed in 2012, but it seems that lists passed in to a lispfunction, get interpreted as if the first items was a dotted pair code.I first noticed this on a tool that takes three integers as an rgb color.
On some values, it shows null for the args in.On some, it reinterprets as if I am passing in a point.
If I pass in '(1 2 3), I get (5009, (1,2,3)) in .net so that is a 3d point.
Note that this alone is a bug, as its a list of three integers, not a point.
If I pass in '(10 20 30), I get (10, (20, 30, 0)) in .net
If I pass in '(228 27 185), I get null in .net
If there is going to be any interpretation going on, it should be because I sent in a dotted pair list. How Autodesk wants us to pass in lists so they come in as just a list of values sent in. URL....

How can I condense the 'history tree' that lists all the function? Like, putting multiple sketches into one folder and then being able to expand it to display all of them?

This seems absolutly silly.
(setq p1 (getpoint))
(setq p2 (getpoint))
(setq Dist (distance p1 p2))
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.

How do I keep the fill ON the object that gets selected so I know not to pick it again as move through the drawing?
How /or/ where can I get a listing of my SetVars.
Running the Setvar (?) command doesnt offer a description for each?

This morning the shop brought back a set of drawings and requested that I provide a cut list for the fab department. Our drawings consist of an assembly drawing and materials list on the first page with several individual parts on each of the following pages. I am looking at including a column in the ML for the operation ( laser, saw, shear) and sorting the list by it. However when I do this the Item Numbers on the list are all confused. If a person were to look at a balloon on a drawing and then attempt to find it in the list it would be difficult and time waster.
The questions.
1. Is there a way to renumber the item list after sorting the material?
2. If I place an assembly view off the edge of the sheet for each of the following sheets and then place a materials list on each sheet, is it possible to create a plugin that would find which parts are on the sheet and hide all the other parts on the list? I have just started going through the "my first plugin" tutorial and this sounds like a place where it should be useful but I don't know which tags I need to look for.

I am trying to write a piece of a program that gets the layers from a drawing, and checks each one against a list of layers. If the layer is not a member of any of the lists it asks the user which layer list to add it to. This is what I have so far, but every time I try to run it I get a bad argument error.
(setq layerspresent (vla-get-layers (vla-get-activedocument (vlax-get-acad-object))))(setq i 0) (repeat (vla-get-count layerspresent)(setq thislayer (vla-get-name (vla-item layerspresent i)))(cond(((progn(or(= nil (member thislayer 0list))(= nil (member thislayer detaillist))(= nil (member thislayer clearancelist))(= nil (member thislayer clearanceelist))(= nil (member thislayer doorsdrawerslist))(= nil (member thislayer hiddenlist))(= nil (member thislayer hiddenelist))(= nil (member thislayer deletelist)))));ifs((progn(initget "0 DEtail CLearance CLEarance-e DOOrs-and-Drawers HIdden HIddEn-E DELete")(setq userchoice (getkword "
[code]...
Depending on the user's choice the layer gets written to an external file where the layer lists get their layers from in the beginning and then adds the layer to the relevant list to use later in the program.

I am trying to sort a list of lists by the size of units.
Here is the unsorted list -
(setq List_Blocks
(list
(list "10x10" "UNIT DOWN-CC" 56)
(list "7.5x10" "UNIT DOWN-CC" 20)
(list "5x5" "UNIT DOWN-CC" 34)
(list "10x15" "UNIT EXTERIOR" 32)
(list "5x10" "UNIT DOWN-CC" 31)
(list "10x20" "UNIT EXTERIOR" 24)
(list "10x30" "UNIT EXTERIOR" 13)
(list "10x25" "UNIT EXTERIOR" 2)
)
)
I would like the list sorted by the first number before the "X" and then by the second number after the "X".
Example of sorted list -
(list "5x5" "UNIT DOWN-CC" 34)
(list "5x10" "UNIT DOWN-CC" 31)
(list "7.5x10" "UNIT DOWN-CC" 20)
(list "10x10" "UNIT DOWN-CC" 56)
(list "10x15" "UNIT EXTERIOR" 32)
(list "10x20" "UNIT EXTERIOR" 24)
(list "10x25" "UNIT EXTERIOR" 2)
(list "10x30" "UNIT EXTERIOR" 13)

Someday the light bulb is going off and I will understand mapcar and lambda. However.....I have a program that reads an excel file sheets. Sometimes the sheet only has 1 column, sometimes 2 or more.
I need to convert the saved values from the sheet to a list with the text spaced evenly. Unfortunately the text lengths vary. I would like a subroutine to pass the list to and return a list of strings with text aligned with padded spaces allowing for the longest text in each column. I am using the new list in a dialog box with fixed_width_font=true (so columns align).
Example 1-
(setq List1 (list "Col1-Line1" "Col1-Line2" "Col1-Line3-longer" "Col1-Line4"))
(AlignText List1)
returns
"Col1-Line1"
"Col1-Line2"
"Col1-Line3-longer"
"Col1-Line4"
so no padding needed
Example 2 -
(setq List2 (list (list "Col1-Line1" "Col1-Line2" "Col1-Line3-longer" "Col1-Line4") (list "Col2-Line1-longer" "Col2-Line2" "Col1-Line3" "Col2-Line4")))
(AlignText List1)
returns
"Col1-Line1 Col2-Line1-longer"
"Col1-Line2 Col2-Line2 "
"Col1-Line3-longer Col2-Line3 "
"Col1-Line4 Col2-Line4 "
Example 3 -
(setq List3 (list (list "Col1-Line1" "Col1-Line2-longer" "Col1-Line3" "Col1-Line4") (list "Col2-Line1-longer" "Col2-Line2" "Col1-Line3" "Col2-Line4") (list "Col3-Line1-longer" "Col3-Line2" "Col1-Line3" "Col3-Line4")))
returns
"Col1-Line1 Col2-Line1-longer Col3-Line1-longer"
"Col1-Line2-longer Col2-Line2 Col3-Line2 "
"Col1-Line3-longer Col2-Line3 Col1-Line3 "
"Col1-Line4 Col2-Line4 Col3-Line4 "

I am writing a program to grab a bunch of layers from a list, check a drawing to see if the layers are on the list, and if not save to an external file. I have the second part of the program done, but I can't get the first part to work.
I am trying to open a file read the contents and save it to a list.
Here is the code I have so far, but it doesn't even get into the foreach statement.
(setq layerslist (list '"0list" '"detaillist" '"clearancelist" '"clearanceelist" '"doorsdrawerslist" '"hiddenlist" '"hiddenelist" '"deletelist"))(setq count 0)(foreach thislayer layerslist (setq f (open (strcat "C:\filterlists\" thislayer ".txt") "r")) (while (/= (setq text (read-line f)) nil) (setq (read thislayer) (cond ( (= 0 count) (cons (cons 8 text) (read thislayer)))( (append (read thislayer) (list (cons 8 text))) ) );cond );setq (setq count (+ count 1)) );while (close f) );foreach
I've also attached one of the text files. Im doing something in the wrong order, or I have something inside the wrong set of parenthesis.

[URL]The example near the bottom shows an unfolded sheet metal part being exported to DXF and there is an option to change the output format in that example. But I don't know how to get to it from a IPT file that is a standard part.
I started with a IPT file and exported as a DWG.Then I created a Layout with the view that I wanted in DXF format and used Save As, selected DFX and I got three DXF files, Model, Layout_1 and Layout_2.
However, I have no way of knowing what format was used for the DXF output. I want AutoCAD version R12. how to interpret the hyroglyphs in the help pages?
Example:
[URL]
Export DXF Options
That page is not useful. It seems to have been written for an earlier version of Inventor. I am still running 2013.
Maybe this is because I have Inventer and I do not have inventor Pro. Is that the problem here? Is this ONLY possible with inventor Pro?

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? CommandMethods work just fine, and i'm not seeing any errors. in fact i'm using the most basic of functions, just returning the arguments. and nothing. Any diagnostic or something to determine what's the matter?
<LispFunction("HelloWorld")>Public Function HelloWorld(args As ResultBuffer) As ResultBuffer Return argsEnd Function does nothing, when i setq a variable on it, it's just nil.

I am currently in the process of re-writing my VBA in .net.In VBA I successfully used AcadDocument_BeginClose which called lisp functions.It would be nice to have all code in the same environment I need to transition my changes.
Therefore I need to call lisp from .net.My function works well when run withing the cad files session but does not appear to call the lisp when called after the BeginDocumentClose.
Is it possible to call a lisp function after the BeginDocumentClose event?

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.

In asp I'd write:

JobNumber = arrFileName(0)
DrawingTitle = arrFileName(1)
SheetNumber = arrFileName(2)
I'd like to do the same thing in lsp. I don't want to be limited to three fields so the split function is perfect.Is there an equivalent?

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 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?

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).

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))
