AutoCAD Visual LISP / AutoLISP :: Distinctions Between Ssget And C# PromptSelectionOption Method
Feb 5, 2012
Distinctions between AutoLISP functions ssget and C# PromptSelectionOption method.AutoLISP ssget function is apply a function with no options and does not require an object selection.pre-selected target object should respond to the selection set.
However, and C# PromptSelectionOption, ignoring the pre-selected objects, select the new object is required.using the features of C# Prompt Selection Option expressed AutoLISP ssget do the same in,

I've been twigging around with a selectionset, but no luck. I need to build a ss with several named blocks and a few dynamic blocks which get selected as anonymous. Unfortunately not all dynamic blocks should be selected and I can find no way of either filtering out a list of dynamic blocks to exclude nor any way to campare to a list of dynamic blocks that I want selected. Below is the best idea that I had but if I wrap it into a foreach with an exclusion list, I get an empty selection set returned. (I'm guessing that I need to trim the pairs each iteration and only return the matches instead.)
(SETQ blklst (LIST "Cleaner" "DRAIN" "Return" "Therapy""PoolLight" "Paraleveler" "Waterleveler" "Skimmer" "UMSLEEVE") blst "Cleaner, DRAIN, Return, Therapy,PoolLight,Paraleveler,Waterleveler,Skimmer,UMSLEEVE")(IF (AND (SETQ ss (SSGET "x" (LIST '(0 . "INSERT") (CONS 2 (STRCAT "`*U*" blst)) '(410 . "Model")))) (FOREACH i blklst (MAPCAR '(LAMBDA (x)(IF (NOT (EQ i (VLA-GET-EFFECTIVENAME (VLAX-ENAME->VLA-OBJECT (CADR x)))))(SSDEL (CADR x) ss) ) ) (SSNAMEX ss)) ) ) (WHILE (SETQ Ent (SSNAME ss 0)) (SETQ BlkName (CDR (ASSOC 2 (ENTGET Ent)))) (IF(SETQ tempList (ASSOC BlkName EndList)) (SETQ EndList (SUBST (CONS BlkName (1+ (CDR tempList))) tempList EndList))(SETQ EndList (CONS (CONS BlkName 1) EndList)) ) (SSDEL Ent ss) ))
The other code is long and I'd rather not confuse things; if I do not try to filter out any Unames, then everything works great and fast. Once I add in the "foreach i blklst" the code breaks and I get:
; error: null interface pointer: #<VLA-OBJECT 0000000000000000>
returned.

I wonder if I have to check if the "ssget" is empty.
I have a lisp to zoom extents in visible objects on the screen.
My interest is to filter before applying:If I have selected objects, it zooms in these objects. If I'm not have selected objects, continue as it is today, applying a zoom in the visible scene.
The result would be similar to a zoom of "3dsmax" (press the Z key)
The atual code
(defun c:ZOBJECTS(/ selectprev)(SETQ selectprev (SSGET "_P"))(command "._UCS" "View")(command "._zoom" "extents")(command ".__zoom" "object" "cross" "-1e99,-1e99" "1e99,1e99" "")(command "._UCS" "previous")(command "._select" selectprev ""))

Is there any way to isolate an item in a list for a filter? I'm setting a filter for SSGET and know that I can use the dotted pairs and I know I can use logical comparisions but what I really want to do is filter a single varialbe in the DXF group 10. For example, I'd like to only get entities with a specific Z value in DXF 10. Or even better to filter for a specified range of Y value or X value in DXF 10. If I could write something like (cons 10 (list * * 8.0)) where the asterisks were wild cards, that would do it but I'm not aware of such a wildcard. Is there any way to isolate a portion of DXF 10 in the filter?

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.
"2''CW-52.0 WSFU"
"2''HWS-48.0 WSFU+12 GPM"
"1"HWR-12 GPM "

I have this code that I wrote years ago that I want to update to select two types of civil3d objects and show them selected with grips on the screen. This function works fine
(defun CELFEATURE ()
(ssget "_X" '((0 . "AECC_FEATURE_LINE")))
(setq sset (ssget "P"))
(if sset
(progn
(sssetfirst sset sset)
;(command "_.PROPERTIES")
)
)
)
(defun cF () (CELFEATURE))
but if I add the extra object like this which I assume is the wrong syntax i only get the second type of objects. Need correct syntax I should be using for selecting more than one object in an ssget statement.
(defun CELFEATURE ()
(ssget "_X" '((0 . "AECC_FEATURE_LINE","AECC_AUTO_CORRIDOR_FEATURE_LINE")))
(setq sset (ssget "P"))
(if sset
(progn
(sssetfirst sset sset)
;(command "_.PROPERTIES")
)
)
)
(defun cF () (CELFEATURE))

I'm having an issue with using the SSGET to select a block so I can move it. I'm changing the UCS to be at the center of the top view in the program(user selects center) and the block is at 0,0,0 after changing the UCS. However when I use SSGET it doesn't select it. So I used:
(setq en(car (entsel "
Select a block :")))(setq enlist(entget en))
and it lists the DXF Code of 10 as
(10 15.0893 13.5165 0.0)
How can I then select it if I don't necessarily know where the block is going to be?

(foreach layr layerlist
(setq player (car layr))
(if (setq ss (ssget "x" '((0 . "*polyLINE") (8 . player ) )))
(command "pedit" "m" ss "" "w" 0.15 "")
(princ "
No polylines exist!")
)
)
However all i keep getting is Bad SSGET list value at the command line,

If you do a LIST command on a dynamic block... AutoCAD tells you the Block Name as well as the Anonymous Block name.
How can I use ssget to snag all Dynamic Blocks that use the 'Real Block'?

My script for going through table styles is almost complet except for the Cell Styles.
I can see that the method is there:
; IAcadTableStyle: AutoCAD IAcadTableStyle Interface ; Property values: ; Application (RO) = #<VLA-OBJECT IAcadApplication 0000000140012308> ; BitFlags = 3 ; Description = "Standard" ; Document (RO) = #<VLA-OBJECT IAcadDocument 0000000030b71ed8> ; FlowDirection = 0 ; Handle (RO) = "678" ;
[Code] .....
However I am having trouble using it in a function:
Following is what I have
(setq GetCellStyles (vlax-invoke-method TableStyle 'GetCellStyles 0))
(vlax-dump-object MergeProp_GetCellStyles T)
(vlax-for MergeProp_cells MergeProp_GetCellStyles
(progn
(vlax-dump-object MergeProp_cells T)
))
GetCellStyles is nil
I have trouble finding the expected.

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.

Is there a way to programatically set a visual style before a drawing actually opens?
We have some huge models and people seem to forget to change their visual styles back to 2D wireframe before saving and exiting drawings. Some models will crash on some workstations when trying to open in a rendered mode.
I found a lisp with a function that looked to set viewport visual styles. But it does not seem to be supported anymore. --> (vla-put-VisualStyle vport 1)

Is it possible to execute a certain command based on multiple selections withinin a dcl? for example: two radio colums, one with selections A and B, and a second with selections 1 and 2. is it possible to program commands based on user selections from each column? ex: if A and 1- do a command. A 2- do a different command, etc...
I tried :
(action_tile "key1" "(setq A t")
(action_tile "key2" "(setq B t")
(action_tile "key3" "(setq 1 t)(done_dialog)")
(action_tile "key4" "(setq 2 t)(done_dialog)")
(if
(and (a) (1)
)
(command ...
but was unsuccessful. no matter which combination was selected, the command under all combinations would run.

I am trying to find a lisp that would get an attribute value (tag name = NBR_5) . I'm trying to run a simple routine that would let the user place the value from the titleblock attribute as text on a drawing. I see a ton of articles regarding getting attributes but I am not well versed in programming.

I'm trying to find acceptable point values to feed to the vlax-3d-point function for a vla-addmtext function. With vanilla lisp I just provide the point as x y = "7/32" "2-3/8". So I assumed that I could drop a 0 in for the z like: (VLAX-3D-POINT "7/32" "2-3/8" 0).
Then I thought I was going to be tricksy and try (vlax-3D-point (getpoint)) believing that I could pick the point and get what I need to feed the function, but yet again, no deal. The command line gave me:
node
of #<variant 8197 ...>
Nothing I can use in my code. So how do I find the point in a format that vlax-3d-point will like?

I use Spell Check regularly and I always check the entire drawing. I would like to add to the Spell macro so that when I pick Spell from the toolbar it goes past the Check Spelling window and begins checking the entire drawing.
I believe I need to insert Alt S into my macro to select Start from the window to begin the check. Is there a character or series of characters that will represent Alt in a macro?

I upgraded from Autocad 2004 to 2012 recently and my lisp file doesnt work anymore.
what it's supposed to do is when looking at the layout tab that you want you can switch to the model space location of the same zoom as the layout tab without messing with the layout zoom.
(defun c:msp ()
(setq cm (getvar "cmdecho"))
(setvar "cmdecho" 0)
(command"view" "d" "tmp")
(setvar "tilemode" 0)
(command"pspace")
(princ "Click TWICE on desired VPORT: ")
(command "mspace" pause "view" "s" "tmp")(princ)
(setvar "tilemode" 1)
(command "view" "r" "tmp")
(setvar"cmdecho" cm)

Is there a command that is the opposite of starting an application to open up a file? Like:
(startapp "PlaySound.exe" (findfile "CuckooClock.wav"))
Instead of starting an application, how to shut all of its instances down. Let’s say I have iTunes and/or Internet Explorer w/ a few tabs open and I can close them down without getting to the application to terminate it the usual way.
Naturally,
(endapp "iTunes.exe") doesn’t work :-))

I have a drawing that has 2D pipeline (only x and y, z value =0) and 3 topo contour lines ( with x, y and z vaules). I need to divide the the 2D pipeline into say 2000 points and then get the corresponding z values from the topo contour lines. I think it can be done by interpolating between the z values for the two apparent intersection points of the 2D line and the contour lines, the x and y values will be the same for the points that falls between these two aparent intersections. Is there any lisp out there that can do that.
