What about creating an AutoLisp selection set from .NET - is it possible, if so I would prefer to do that instead?
The goal is to create some objects in .NET (using activeX or managed code) and then have some way to access these objects via the command line I'm assuming they only way is using an AutoLISP selection set.
On a Chinese computer with Windows XP, the layout name via ActiveX is displayed correctly "A3 -布局-02" on the variable laynam.
But under Windows 7 64 Bit I get this "A3 -??-02". So all ActiveX objects with AutoLisp commands do not transfer the Chinese Unicode characters, also on a system in china.
But the pure lisp command (layoutlist) for example returns always the correct characters ("A3 -布局-02")
Do I need any Chinese dll’s for ActiveX dependent language? On my test PC I installed the file autocad_2013_traditional_chinese_language_pack_win_64bit in the hope I get shared files for ActiveX but this did not bring success.
Hatch objects: Note To access this property, use the IAcadHatch2 interface.How can I access the Object.Area of an AutoCAD hatch. AutoCAD 2006 has properties that can be assigned to Fields so why can't I find the object att- area in any lisp vars?
Having tested it in different ways, it looks like at the end, el1 represents the association list that I want my object to have, but it doesn't want to update.
I am modifying stuff in a dynamic block insert entity. There is no "endblk" entity at the end of these definitions and I need to cycle through every entity within the block definition. When it gets to the last entity, I get an error because you cannot entnext passed the last entity. There are 2 things:
1. How to retrieve the # of entities in a block without cycling through it. Or 2. A quick lesson in the *error* function, I cannot figure out how to implement this. I basically want to to say:
(if (entnext myent)) returns a error, don't abort & continue on.
When dynamic blocks are inserted they're assigned an anonymous block name. I'd like to be able to retrieve the name of the parent block after selecting the block on screen using AutoLisp.
I've created a lisp that draws the boltholes of a pipe flanges, using the correct number of holes, at the correct diameter at the correct bolt-hole diameter and then rotates. Everything works seamlessly, when i do just one flange. But I've discovered that fewuently there will be mulitple times when a user will have to perform the command.
So the idea I had was to do the following:
Select all circles with (setq CirclesFirst (ssget "X" (list (cons 0 "CIRCLE"))))
Go through the code to create the new circles.
Select all circles with (setq Circles (ssget "X" (list (cons 0 "CIRCLE"))))
Remove selection set "CirclesFirst" from "Circles".
But what for some reason (command "_.select" Circles "R" CirclesFirst "") does not work.
I'm trying to fix an issue with entlast where if the user hits escape during the process, the wrong entity gets erased, etc. Here's the problem code...
From a function that would have just inserted a dynamic block at 0,0 then modified it - here's where we pick up..
I'm putting together some quick function that I can send 2 arguments and get from it the total area of a given hatch on the given layer. I think everything is in order but I'm having trouble with the selection set filter:
(DEFUN GET-HATCH-AREA (HATCH LAYR / area sset) (COND((AND(ssget "X" '((0 . "HATCH") (2 . HATCH) (8 . LAYR))) (SETQ area 0) (VLAX-FOR H (SETQ sset (VLA-GET-ACTIVESELECTIONSET (VLA-GET-ACTIVEDOCUMENT (VLAX-GET-ACAD-OBJECT)))) (SETQ area (+ (VLA-GET-AREA h) area))) (ALERT(STRCAT "Total area = " (IF (OR (= (GETVAR "lunits") 3) (= (GETVAR "lunits") 4) ) (STRCAT (RTOS area 2) " sq. in. (" (RTOS (/ area 144) 2) " sq. ft.)") (RTOS area) ) ) ) (VLA-DELETE sset) ) ) ))
I can create an empty selection set (setq EMss (ssadd)). As I loop through a list I can use the counter to create selection sets on the fly by using:
(set (read (strcat "ss" (itoa cnt))) EMss) and even keep a list of the ssets created with (setq sslst (cons (strcat "ss" (itoa cnt)) sslst)). But when I try to add an ename to the ss with (ssadd ename (read (strcat "ss" (itoa cnt))), I get a error: bad argument type (SSADD NEXTE (READ (STRCAT "ss" (ITOA CNT)))).
why I can create the sets but not add to them this way? I can add to them from the command line.
I wrote a lisp program which creates a selection set using ssget. Then I use the bounding box commands to get the lowest point of that selection set. Now I want to move that selection set as a whole using the vla-move command. Can we vla-move a selection set?
To get the 'File Selection dialog box' in AutoCAD via LISP, which command should I use other than 'GETFILED' ?
I have a program which using GETFILED to select the drawing file , but I think this dialog box size is too small to browse folder/file , as you cant see the favorites list and you cant resize the dialog box.
I'm working on a lisp that goes through a whole list of files and does different things to those files. I've been racking my brain for a way to select just a folder via a dialogue box, but haven't found a way. I'm sure it can be done with dcl, but I don't know where to start.
This would not be the standard "file" selection box, but would only list the folders and let me select one even if there are others "under" them. This is what I'd like it to look like.
I'm not sure if there is a standard AutoCAD box that I could call for this or not
I have a lisp routine that creates a "frame wall" and I want to be able to automatically dimension said wall within the same routine. I have created two sets of points, each set being on its own new layer. I have made selection sets of each set of points, and want to cycle through each set dimensioning as required. This what I have so far for this part of the routine:
When I run the program I get the error: bad point argument. So what I think is happening is that the ssname command is not returning the actual value but just the name? I am new to AutoLisp and even newer to selection sets so be easy... Along with this, I am also curious as to how a selection set is ordered when it is chosen ie how does it determine what would be in (ssname sel1 0). Also, how would one go about deleting the points in these selection sets after the dimensioning has been completed.
Looking to make a selection set of points that are on a specific layer, and then create a dimension between, in this case, two points. I feel like it should be very simple, but I can't get it to work for the life of me. Here is the test code I've been playing around with:
when it comes to setting paperspace as the 410 ssget list value as the name can be modified and I need it to work in all drawings. I tried setting a variable to the paperspace layout name and using a print function at the (410 . "model") point but without sucess.
How to get the individual components of a block that has just been exploded within a lisp routine into a selection set. I want to alter the layer of each element to the insert layer of the block. I may also make one or two other changes according to what I find in the block.
I wrote a lisp program which creates a selection set using ssget. Then I use the bounding box commands to get the lowest point of that selection set. Now I want to move that selection set as a whole using the vla-move command. I am having trouble doing this. Is this possible? Can we vla-move a selection set? Is there a workaround?
I downloaded a lisp routine that will align block attributes. The problem is I can only select the attributes one at a time. I'd like to be able select multiple attributes using the selection window or a crossing window, but I haven't had much luck. If you use the AEATTSHOW command, it give you a prompt to "select using window" by pressing W. I'd like to have the same functionality for my Align attributes routine.
Below is the portion of code I currently have to select attributes one at a time:
;* Select all attributes to align with the parent selected above and add the attribute entname and the block ;* entname to a list in format ( (AttrEntName BlkEntName) (AttrEntName BlkEntName) (AttrEntName BlkEntName) ) ;* while (/= TempAttr nil) (setq TempAttr (nentsel " Select Attributes to align: ")
and so on, but the example above caters for situations the users enter the values of 1, 2, or 3. If the user enters anything else I get a nil response from AutoCAD. So I devised the following
(if nil (alert "Wrong selection"))
but no response from AutoCAD qua an alert
also tried to be more in uniform with the rest of the lisp and wrote
I have some strings like the ones below. They are always in the same format. The first line is Cold Water, the second is Hot Water and the third is Hot Water Return.
I want to build a selection set based on whether it is CW, HWS or HWR. Right now I have a routine to retrieve the string by using ENTSEL. In other words if I want to use the line of text for Cold Water I have to select it.
I'd like to be able to window them all and filter the SS for only the string containing CW and conversly HWS and HWR. SSGET function filter.
When you select similar using autocad it select similar in entire drawing. What i want is i am able to select similar using the same setting of selecting similar but with window selection instead of entire drawing ?
