AutoCAD Visual LISP / AutoLISP :: Align Block With Two Selected Destination Points
May 13, 2013
I am trying to write a program to align a block with two selected destination points.
- first the user is prompted to select a lwpolyline of a block entity
- then he is prompted to pick two destination points
I face problem with the sub-routine SegmentPts. It is supposed to return the coordinates of two vertexes on both sides of the picked point on a lwpolyline using entsel. But here in my program, when i am picking a point using entsel on a lwpolyline inside a block entity, it is not returning the two vertexes on both sides of the picked point. In stead, it returns some other points of the selected LWPOLYLINE. Why it is doing so? Where is the problem in my program?
It works fine with my other programs where i pick on a LWPOLYLINE entity. In this particular case, the LWPOLYLINE is inside a Block entity and the program is not returning correct points.
Please check Lisp Program below:
(defun C:alb()
(setq ent1 (entsel "
Pick on one side of LWLINE ofa Block:" ))
(setq ent (nentselp (cadr ent1)))

I am trying to insert a norht block oriented on two selected points with the following
(defun c:North ( / ss )

I am not sure how to (a) erase the selected north block, then (b) make the insert north block in its place bit work.

I started a lisp that moves blocks according to their attributes and align numeric value in x 0.0. I work currently selected point by point. I will wish it to run at once on a selection set (I am angry with entsel).

What I am trying to do is figure out the steps to "reset" geometry within blocks. (Assuming rectilinear).
That is to say find the min X value and Y Value and align that with the 0,0 of the block. To be able to do this on a drawing full of blocks. Essentially fixing poorly defined blocks whose origins are miles/km's away!

I found a lisp for counting of selected block in a table drawing, but I can not remove the bottom line of this lisp that displays "total" blocks. How to remove this line from "total" that is created in the last row of the table that lisp.
lisp : ========================================
(defun c:TABL (/ blk_id blk_len blk_name blks ent h header_lsp height i j TOTAL
len0 lst_blk msp pt row ss str tblobj width width1 width2 x y

I got this code in a web trawl to insert a block to points taken from a txt file......
its coming back with an error as follows:

What does this mean and how can I fix it.

When i export revit drawing with revit family
the revit family become block in autocad like this
M_Single-Flush - 700 x 2200mm-278353-Ground Level _0_45
usually i want to remove the ID and view name to become like this without have to re type because it is tedious
M_Single-Flush - 700 x 2200mm
something like how many letters you want to remove from last to first ?
or something better like remove this last two dash and the letters embedded inside ( that separate name-ID-View name) -278353-Ground Level _0_45?

I currently insert certain dynamic block into drawings with a short function that first inserts the specified dynamic block and then immediately changes the visibility state to one specified as an argument to the function.
I'm wondering if it is possible / better / faster to somehow insert the dynamic block with the decided visibility state simultaneously. I've been amazed by many capabilities of VL so I wouldn't at be surprised if this can be done. (the dynamic blocks I'm inserting could have many multiples in the drawing but I need this method to only affect the one being inserted at the time the function is called. I currently use entlast to decide which one is being inserted.)

I'm trying to create a model of arrow with which I could place in drawing in any length and orientation I want with lisp. I was imaging to place two point on this arrow and by placing the two points on my drawing, the length and orientation of the arrow would be define.
I'm trying for hours to create it and my grip for polar stretching don't stay still on my arrow (suppose to be on the peak but go far if I stretch it).

I have a dynamic block that I would like to insert via a lisp routine. When the routine is run from my menu I would like to select two points on the drawing area. Then I would like my dynamic block to be inserted at one of the points I selected and then I would like a specific "point" of my block to be stretched to the other point that I selected. I was wondering if this is possible with LISP? I have my old LISP program I wrote that draws a leader and then inserts my block but that was before I started working with dynamic blocks.
Here is my current
(defun c:wldsym()
(setq osnapold (getvar "osmode"))
(setq orthold (getvar "orthomode"))
(setq dimsc (getvar "dimscale"))
[code]...........
wld1r.dwg is my current block. It has some dynamic properties already. But I'm trying to add new properties that can be seen in my working test drawing wld1r-new.dwg
When using my code with "wld1r.dwg" you can see how everything behaves right now. Then open "wld1r-new.dwg" and note that the insertion point and a stretch point my default are in the same spot. Work with the two stretch points and look at how the block reacts.

For a program i am working for i have to extract the base point of a dynamic block.
This can be done perfectly by this function:
(cdr (assoc 10 (entget (car (entsel)))))
But i want the entity selected based on a previous slected point. So for example when i selected pt1 (which is a point at the border of the dynamic block) i want to be able to extract the base point on the block whit this point.

I am currently using this lisp routine to export selected objects as a dxf to import into another program:
(defun c:dxf ()
(command "_dxfout"
(getfiled "DXF File:" "c:/dxf/" "dxf" 1)
"_Objects" (ssget)
"" ; completes selection
"_Version" "2004"
"16" ; non-default number or other option if desired, with followup line(s) if
necessary
)
(princ "2004 DXF Created")
(princ)
)
this saves the dxfs to a location of C:DXF
I would like it to save to a different location, the desired location is within the same root folder that the drawing is located in and is called "DXF-Programs-Releases"

Using lisp to insert a dynamic block that uses an align parameter. I have a rather elaborate lisp program that I am adding to so that it can insert one of my library blocks which contains an alignment parameter. It sure would be nice if the alignment could be automatic and not involve additional user input.
What I am hoping for would be a way to allow the alignment parameter to do its job when inserting with the following line of
(command "-insert" BLK-N-PTH ins 1 1 rot)
I was catching the rotation value of a "parent" dynamic block by using vla-get-rotation and then correcting for UCS and converting form radians to degrees, and this works well for straight blocks, but some of my blocks are curves and the whole paradigm falls apart with then.
So far my workaround is to have the user also pick the rotation, which does seem to work:
(command "-insert" BLK-N-PTH pikpt 1 1 (while (eq (logand (getvar "CmdActive") 1) 1) (command pause) ))

I've gotten these two routines from different threads on here. One works with *text and blocks. The second works with multileaders.
I'd like to merge the two so one command can work with a selection set of any of the above objects (assume selection set of mixed objects - some multileaders, some text, some blocks)
(defun c:at ( / ss ang *error*)(vl-load-com)(ErrorHandler '("cmdecho" "osmode"))(setvar "cmdecho" 0)(setvar "osmode" 576)(setqss (ssget '((0 . "*TEXT,INSERT")))ang (getangle "
Select two points along desired alignment:"))(mapcar'(lambda (x)(vla-put-rotation(vlax-ename->vla-object x)ang))(mapcar 'cadr (ssnamex ss)))(*error* nil))(defun c:test (/ ss ang i sset)(vl-load-com); Tharwat 17. 05. 2011 (if (and (setq ss (ssget ":L" '((0 . "MULTILEADER")))) (setq ang (getangle "
Specify Rotation Angle :"))) (repeat(setq i (sslength ss)) (setq sset (ssname ss (setq i (1- i)))) (vla-put-TextRotation (vlax-ename->vla-object sset) ang)) (princ)) (princ))
Or see C:AT and C:TEST in the attached file

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.

I need a LISP program that prompts: "select text(s)" then I select for example 100 text in open drawing file.
after that this program creat a file (LIST.CSV) and write each selected text in line by line of this file:
result text file (LIST.CSV ) should be:
Text1
Text2
Text3
...
...
Text99
Text100
ofcourse Text1 is the content of a text object.

Any way to detect of there are objects currently selected using Autolisp, visual lisp or even VBA. I would like to be able to do something using that as a conditional, so that (assuming the hypothetical variable isSelected is an on/off indicator of whether or not something is selected) I can code something like this:
(if (isSelected) (...))

I get an AutoCAD drawing from my conveyor manufacturer who have buried a block (tagname) in all of their conveyor blocks.
The only way to remove them is to manually use BEDIT and erase the tagname block.
Is there a way through Autolisp to search all blocks in a drawings and if the tagname block is part of the definition of the conveyor block, erase the tagname block or redefine the conveyor block without the tagname block.

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.
Need a bit of code that handles this?

Create a routine that looks for a block based on a portion of that block name, using a specified path or search path.
For example, block to search for is BLOCKABC123, so if someone inputs ABC or 123 as a block name, it will locate that block within that folder and inserts it into the drawing at a user specified location.
Ideally, if there is a check in that if it finds more than one match, then perhaps it flags or prompts you to choose 1, 2, or 3 option which block to use. But I can live without this special function if it requires too much time to code.

I need to match few attribute values from one block to different block. I download a lisp file called; ca.lsp which can match the single attribute value. I modified it for more than one attribute value matching. It is ok but still wish to overcome two issues for batch prcess
1. picking up the blocks by selection
2. click the alternative block numbers of times to match the numbers of attribute values I needed.
How to modify this lisp I can run it by block name selections instead of picking selection which enable me to run batch process for numbers of drawing? That will be good...
Lisp & Demo file attached (Match attribute value, A, B & C to Attribute 1, 2 & 3).

I am learning autolips and i found a problem that i can´t solved.
(vl-load-com)(defun c:pmb ( / ss ent pt )(prompt "
selec block : ")(setq ss (ssget '((0 . "INSERT")))) (setq ent (ssname ss 0)), (setq pt (cdr (assoc 10 (entget ent)))) (command "point" pt))
wich this code you select one block and insert one point at insert point´s block.
which this other code yo select all block and insert all point.... but in one block
(vl-load-com) (defun c:pmb11 ( / sele cod bloque nbloque lista pt ) (prompt "
block: ") (setq sele (ssget ( List'(0 . "INSERT"))) Cod 0 )cod (1+ cod) (repeat (sslength sele) (setq bloque (ssname sele cod)) (setq pt (cdr (assoc 10 ( entget bloque)))) (command "punto" pt) );repeat )

I have a block that i want to insert several times and revised each one to be different to do this i would have to insert it and rename the blocks that come in and then reinsert i would like to insert and have a lisp explode the main block and rename the other 2 blocks with a suffix at the end depending on how many times its in the drawing... can this even be done? My original block name that will be first inserted is "BENT PULLEY NOTES" it needs to explode after i drop it in and then there are 2 blocks within that called "Bent Pulley" and "Bent Pulley DYN" that i was hoping to keep the names but add a number at the end depending on how many are in the drawing already...
here is a lisp that i have found... it would work if i didn't have nested blocks and only wanted the one block to be insert and not explode...
(defun c:Test (/ e i name Bname )
(setq e nil)
(command "_.-insert" "Drawing1.dwg" pause "" "" "")
(if (setq e (entlast))

I have a dwg with 40 blocks that have a non-annotative property. I can go through 1 by 1 and change the property to annotative and redefine the block. Is it possible to automate this? I have done some google searches but have not found anything I am able to cut and paste or put together to get it to work.

I need a program to move some selected text to a line something like as extend command but for text objects!
suppose that there is a horizental line (y=constant) or vertical line (x=constant) and some selected text(or other objects), I want a lisp program that move these selected text (or objects) by their "insertion point" to this line.
in other word, if the selected base line is horizental (y=constant) then property of "Y" of all selected text should change to line's "Y"; and if selected base line is vertical (x=constant) then value of "X" of all selected text should match to line's "X" value.
for example, for base vertical line (x=constant) and 3 selected text(or can be any object) result is:
text1. | text1.|
text2. | ===> text2.|
text3. | text3.|
| .text1 |.text1
| .text2 ===> |.text2
| .text3 |.text3

I want this information to be added to the blocks as hidden attributes so that i can extract them by attout. The work to be done is : attout to excel, autofill an attribute (numbering) then attin.
but my problem is that i cant think of a way to number those blocks IN ORDER (ie top to bottom or left to right) unless by sorting them in excel first by their x or y coordinates
