AutoCAD Visual LISP / AutoLISP :: Find Object Associated To A Field

Nov 1, 2011

We use multi-leader objects in our drawings. When the multi-leader and its value are to be replicated throughout the drawing, we create mleaders with fields that show the contents of the first mleader. That way we can update only the value in the first mleader and all of its children will update as well. It works nicely for us.

Here comes one snag. If one of us opens a drawing with which we are not intimately familiar, we don't know which mleader is the parent of which children. There might be fifty parents and four hundred children in a drawing so going through them by hand is a big productivity drain.

What I need to do is write a routine that will let the user select the mleader that includes the field and have the routine highlight and/or zoom to the parent object.

I thought I should be able to find that info in the dxf codes for the mleader, but I am either missing it or it's not there.

AutoCAD Visual LISP / AutoLISP :: Default Formatting For Field / Object-Polyline-Area

Aug 10, 2012

I create a lot of fields that reference a polyline area and I'm constantly having to change the default formatting values. I would like it to default to an Architectural format, WITHOUT the appended "SQ. FT." (which often takes up too much space), with a precision of 0 and using a comma as the Thousands Separator.

Is there any way to set these default values?

AutoCAD Visual LISP / AutoLISP :: Using Formula Within A Field

Apr 11, 2012

I am currently using a field for my elevation tags. The field reads the y-value of a line and displays the results as the elevation. Our local jurisdiction requires that we list elevations from above grade (A.G.L.) as well as from bottom of base plate. The difference is usually 6"-12".

I was wondering if I could create another field that would read the same y-value of a line, but then subtract a predetermined value (6") and display the results.

Currently we have to do the math ourselves and this leaves room for errors and is often very tedious.

AutoCAD Visual LISP / AutoLISP :: Conditional Statement In Field?

Aug 19, 2013

I created a block, that uses the Y coordinate of the block and returns it's location in a field.

I would like to be able to indicate weather the value is negative or positive. If Y coordinate is less then 0, then the field indicates "-" in front of the value. But if the Y coordinate is positive, I couldn't find a way to place "+"symbol in front.

Is there any way I could introduce a conditional statement saying: if Y>0 then add "+" in front?

AutoCAD Visual LISP / AutoLISP :: Getting Field Formulas From Sheets Set?

Dec 6, 2013

I had a routine that extracted field values from text and atts, but noticed this morning it did not work on fields from sheets sets.

I looked at the code and realized if a field formula is beyond 256 chars, the dxf codes store it in multiple groups.

Here is the revised code that deals with thos multiple groups (3 and then 2):

;GET LIST OF TEXT AND FIELDS FOR A GIVEN TEXT;RETURNS ("PLOTTED BY " "%<\AcVar Login \f "%tc4">%" " DATE" ...);FIELDS START AND END WITH WITH %< >%;(TXT-FIELDS-SEPARATED (car (Nentsel " Select Text, MText or Attribute: "))) (DEFUN TXT-FIELDS-SEPARATED (ENAME
/ DICT ELIST ENDINDEX FIELDS FLDDICT FLST FORMULA INDEX OBJ SPLIT-FLDS TRIMMED-LIST TXT-LIST TXTAFTER DENT FLDVAL FLST-TR) (SETQ ELIST (ENTGET ENAME)) (COND ((OR (= (CDR (ASSOC 0 ELIST)) "TEXT")

AutoCAD Visual LISP / AutoLISP :: Parsing In Field Formulas

Nov 3, 2011

We use Sheet Set Manager fields to keep track of section cuts and details and such.Users are asking me if they can get only the last 4 digits of the sheet number to show up on the section cuts.

Is there a way to parse or truncate a field in the formula area of the field dialog box?I'm familiar with LISP and DIESEL but the file dialog box / formula area does not seem to accept those functions. Will it take a .NET function? If so, what? Or, is there another option I'm overlooking?

AutoCAD Visual LISP / AutoLISP :: Put Field Formula In Attribute Value?

Sep 7, 2011

I am trying to put a field formula in an attribute value. Basically I have a block that has a attribute called QTY and it is equal to 1. I can get the object property to equal 1 with this expression:

%<AcObjProp Object(%<\_ObjId #########>%).Textstring>%

The expression above will show a value equal to 1 (as I would expect)

Lets say I have two blocks now and I have the lisp routine combine the field values to get the expression below.

%<AcObjProp Object(%<\_ObjId #########>%).Textstring>%+%<AcObjProp Object(%<\_ObjId #########>%).Textstring>%

In the attribute dialog box it will show 1+1 instead of 2. My question is how do I get it to show 2 with out opening the formula box and evaluating it?

I have also tried.

%<AcExpr(%<AcObjProp Object(%<\_ObjId  #########>%).Textstring>%)+(%<AcObjProp Object(%<\_ObjId  #########>%).Textstring>%)>%

and

%<AcExpr((%<AcObjProp Object(%<\_ObjId  #########>%).Textstring>%)+(%<AcObjProp Object(%<\_ObjId  #########>%).Textstring>%))>%

AutoCAD Visual LISP / AutoLISP :: Field Update Customscale Viewport

Feb 22, 2013

I'm trying to create a field in a block (titleblock) that will automaticly update when I change the viewportscale.It's mostly only 1 viewport, sometimes a second of even 3rd but, they are not important to the titleblock.

I've read aboud fields and diesel expressions. I've tried and it works. there is only 1 problem,It only works with the object (when field expresssion, object, custom scale) in this case the viewport pressent at that time. 

When i use the same field with the same expressions, it does not recognize the viewport/object.Is there a way to make the field, diesel expression or even something else, work without it's need for a

object name. Perhabs that the expression gets the viewportname from a lisp, something like: (setq ss(ssget "X")) ;some thing like this Can it be done?

AutoCAD Visual LISP / AutoLISP :: How To Use A Field To Display Text Information

Sep 14, 2011

I have a situation where I have a AutoCAD table linked to a Excel table to retrieve lots of general information for a standard drawing. That works just fine. In additionally I can use the fields "formula" field name and select a cell in the AutoCAD table to pull the data from the cell to the field, and this works for table cells that are numeric, but some of the cells are text based, and for these situations AutoCAD simply gives me the #### result. Is there a way to use a field to display text data from a AutoCAD table Cell?

AutoCAD Visual LISP / AutoLISP :: How To Tie A Key From Custom Dictionary To Display In Field

AutoCAD Visual LISP / AutoLISP :: Send Field Value To Multileader With A Block

Dec 10, 2013

I'm trying to send field value to a multileader with a block. I tried:

(VL-CMDF "_.mleader" (getpoint "
Specify leader arrowhead location: ") pause "%<AcVar.17.0 Lisp.*granitelbl* f "%tc1">%")

Maybe it was a naive of me to charge in so boldly. The field appears to have made it in but it does not act like a field and does not reflect the correct value or update. In fact I get no response at all. In fact using "update field" "all" selects the fields but reports that they are locked.

AutoCAD Visual LISP / AutoLISP :: Extract Field Expression of Attribute In Block

Mar 8, 2012

Is that possible to have a lisp to extract the Field Expression of a attribute in a block?Specifically, to extract the property VALUE (TextString) of this attribute.After to extract, I would like to put this text extracted in a different layout tab, in the same drawing. In this way, I will have a text linked to the attribute value between two layout tabs. So, when I have to change the attribute value, the text will be updated automatically.

I know that if I use the FIELD command to manually copy and paste this value it will work, but when I have a lot of attributes it becomes very laborious.

AutoCAD Visual LISP / AutoLISP :: Find Offset Origin Of Layout

May 8, 2013

I want to know the correct way to find the offset origin of a layout in an AutoCAD drawing.  Let say I have a drawing that has many items on it.  And I create a layout showing just the items in the lower right corner of the drawing.  I want to know the offset origin of this layout relative to the Model space.

I came across some LISP commands that are supposed to do just that:
 
(vl-load-com)(setq activelayout (vlax-get (vla-Get-ActiveDocument (vlax-Get-Acad-Object)) 'ActiveLayout ))(setq activeplotorig (vlax-get activelayout 'PlotOrigin)) 

Unfortunately, the commands don't seem to work because it always returns (0.0 0.0).  That cannot be right.
