AutoCAD Visual LISP / AutoLISP :: Read Attribute (diameter) To Draw Circle?
Oct 21, 2013
Can a AutoLISP command be written to read an attribute in a block and draw a circle with the attribute as the diameter using variables? The appilcation is taking the diameter of a tree trunk (the attribute), multipling by 12, and drawing the canopy circle on hundreds of those blocks. So the circles drawn will vary in size.
Not sure how this could be set up, i'm not familiar with LISP writing at all.
1) Read block, single, mulitple or definition?
2) Read Attribute
3) Varaible of attribute, (attribute is an inch measurement...it needs to be multipled by 12 to get feet for final use as circle diameter drawn)
4) Draw circle, variable, with diameter coming from attribute variable (attribute in inches that is multipled by 12)
5) Center point or circle to be block's base point

I'm looking to draw a mleader (with a leader style CLL_Anno) using the block basepoint as insertion point, read two attributes from that block and use those as the text for the mleader. for example: "attribute - attribute". Attached is dwg with blocks with attributes and leader style. (Block is "Trees", Attributes are "V_SPECIES" "V_DBH_DIM")

I'm trying to change a routine i just wrote that draws 3d pipes. I wanted to make it so that when a user selects the beginning point and ending point of the pipe, the LISP changes the ucs to that vector, draws the circle at the beginning point and extrudes it to the second point.
It actually works great except when the ucs changes, so do my user points because of teh origin change. Is there a better way I might get this to do what I wnat it to?
(setq ip (getpoint "
Pick First Point:"))(setq ep (getpoint "
Pick Second Point:"))(command ".ucs" "za" ip ep)(setvar "osmode" 0)(command ".circle" ip "d" od)(command ".extrude" (entlast) "" (distance ip ep))(command ".ucs" "w")(setvar "osmode" oldsnap))

Background: Someone exploded an attribute block and copied it hundreds of times throughout a project, each time changing the Attribute Tag to match the Value they expected to appear in their drawing. The drawing must be xrefed, so the attribute definitions do not appear.
(There is only 1 attribute in the block.)
Proposed Solutions:
1:AutoLISP routine which copies Tag data from Attribute Definition into Value of Attribute Block:
Prompt-Select Attribute Definition
Copy Tag data
Prompt-Select Attribute Block
Paste data into Value
(Allow repeat to speed workflow)(*PREFERRED*)
2:AutoLISP routine which copies Tag data from Attribute Definition into Default Value and creates a new Block:
Prompt-Select Attribute Definition
Copy Tag data
Paste data into Default Value
Create New Block
(Select Multiple Objects)(Creates tons of new blocks which are messy)

If I have a CSV file (with no header) that contains three columns and I want to return values of the second column as a list, how is the best method to do that?
I have seen something where one can separate a string into a list by a divider (in my case, the commas between the three columns) but the actual code for me to inspect was supposed to be in an attached ZIP file which I didn't see as part of the post.
An example of my CSV (as a list) wouild be:
("PO-30-10,PIN OAK,88-15" "PO-30-10,PIN OAK,88-01A" "JS-20-5,JUNIPER,63-04" "PP-40-10,POPLAR,38-22")
and I need the resulting list to be:
("PIN OAK" "PIN OAK" JUNIPER" "POPLAR")
Is there a LISP way to do this - or only VLISP?

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.

Is there a quick way of getting the value of an attribute?
I have an attributed block called "tp_attributes" and it has and attribute called "OrderNum".
I just want to be able to quickly grab that value.

Say I have a block that contains two attributes, one contains a value that is a number and another contains a value that is letters. I have many of these blocks placed in a drawing, could you create a lisp that would return the sum of the number value and return it to the command line along with the letter value. Something like this:
Sum--------Item
128 RP
389 TD1
2389 SP4

I continue with my problems.....
I get attribute value from block and put it in a list:
(repeat (setq cnt (sslength sset))
(setq attValue (GetAttributeValue (ssname sset i) "tag1"))
(setq attValue2 (GetAttributeValue (ssname sset i) "tag2"))
[Code]...
When I try to put them in a table...
(foreach item lst
(vla-setText mytable
row 0
(last item)
)
(setq row (1+ row))
)
only put one ( attValue2) at column, and i like put 2 values, each one in a column in the same row

What is the smallest object I can draw and "SEE" in AutoCAD? I was hoping to prove a point in my introductiory AutoCAD class, but it appears I have been lying!! I tried to draw a cirlce with a diameter of 1.24E-10m. The dot shows up, but I cannot zoom to it. I tried using an enormous zoom scale, but did not have any luck. I am almost positive my instructor introduced the capabilites of AutoCAD by drawing a full scale helium atom, and that was release 14. Is this still possible? Obviously the atom can be drawn, but what are the zoom limitations?

How do I check, with LISP, if a System Variable is read only? In particular ANNOTATIVEDWG. This one is read/write when there are no annotative objects in a drawing, but read-only if there are.

I run into some issues where i need to change an attribute based on where a block is located on a drawing. I started this routine to select the block, and then select the text that I want to change the block attribute to. It seems like everything is working up until this point. What I want to do is then replace the first selected with the second selection. How would I go about doing that? here's my code so far:
(defun C:uf ()
(if (setq fuse (nentsel "
Select Fuse Attribute: "))
(progn
(setq en (car fuse))
(setq enlist (entget en))
(setq fuseatt(cdr (assoc 1 enlist)) ) ) )
(if (setq mt(car (entsel "
Select Text: ")))
(progn
(setq enlist2 (entget mt))
(cdr (assoc 1 enlist2))
(setq wiren(cdr (assoc 1 enlist2)) ) ) )
)

I am trying to customize AutoCAd for a special domain where attribute values need to have a type. I can have a clean integrated solution by manipulating the acad.dcl or base.dcl .I am using AutoCAD 2012 . I want to extend the " define attribute" and "edit attribute" dialog boxes to promt the user for a value type when they define an attribute .I can't find the definition for these dialog boxes in acad/ base dcl files. Ideally I want to add another tile definition to these dialog boxes .If that is not possible atleast spawn a different dialog box from the "define attribute " dialog box that will collect the value type from the user.

I am trying to update my Title Block with a LISP routine (As the title implies).
So far, this is what i have...
(defun c:aTest (/ ss att)
(if (setq ss (ssget "X" (list (cons 0 "INSERT")(cons 2 "TB_PARAMOUNT_ELC")
(cons 66 1)(if (getvar "CTAB")(cons 410 (getvar "CTAB"))
(cons 67 (- 1 (getvar "TILEMODE")))))))
(progn
(foreach ent (mapcar 'cadr (ssnamex ss))
(setq att (entnext ent))
[Code]...
The title block, block name is static. The attribute name is static.
My ultimate goal is to copy the value of one attribute and "paste" that into the value of another attribute, and itterate this through the entire project.

I have a block "MANAGER" with Two Attributes "CETOP" and "CEBOT" I would like a lisp to replace what ever is in those attributes with defined text, for my purposes "Text1" and "Text2". I would like a simple routine that even I can understand so I can apply it to a couple of other lisp projects I have.

I want to edit 1 attribute value in a block to number all my blocks (eg A001, A002, A003...) (example picture attached)
I know about the at tout and at tin but I need a lsp routine that only changes one attribute value without having to double click and go through that.
i attached a lsp routine, how to edit and remove everything except the value part.

significance of extra dxf 1 groups in the entity data of a multiline attribute? I am looking at one for the first time, so I don't know whether or not to expect multiple 1 groups. In the single example I have created there are two and the first one seems to be ignored. Can I count on that being the case all the time? Data for the one I'm looking at follows, and what shows up on the drawing display is only the contents of the second dotted pair with 1 as a key.
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
((-1 . <Entity name: 7ec37d18>)
(0 . "ATTRIB")
(330 . <Entity name: 7ec37d10>)
(5 . "323")
(100 . "AcDbEntity")
(67 . 0)
(410 . "Model")
