WD_OPEN_DWG,(if(not c:fix_me)(if(setq x(findfile "fix_me. If your block and LISP files are both named fix_me replace the default *WD_OPEN_DWG line with this… So once the LISP file and block are created, why not run them each time a drawing is opened? This takes us back to the WD_OPEN_DWG line in the wd.env file. It could also be placed off to the side of a symbol with missing catalog info, or anything else the engineer is unsure of at the time of placement. Values in the attributes will carry across to the new symbol. Once the new symbol is finished the fix_me symbol can be swapped (Swap/Update Block) with the new one. Basically, i want to create a simple command line based routine that allows me to switch point styles. I've checked the help and it suggest the PROGN fucntion and i can't quite get my head round it, lol. This fix_me symbol can then be used when a needed symbol is missing and the engineer is waiting on the CAD Admin to create it. Hi, Could someone please explain a typical IF ELSE statement in AutoLISP. So create a block named fix_me and give it attributes for notes as well as all symbol attributes. Typing ‘fix_me’ will now run the script which zooms in on the first block named fix_me that the script finds. When attaching or publishing two of our CAD drawings, the LISP command returned nil instead of the. (setq xy (cdr (assoc 10 ed))) block insertion point Posts about AutoLISP written by Jay Manaloto. (setq en (ssname ss 0)) entity name of first or only block Look for any block insert on the drawing with a block name of "FIX_ME" Simply copy and paste it into a text file and save the file as Fix_Me.lsp.
“How do I mark a symbol/wire that has a problem, or missing information, and later quickly find it?” Last week this question came up again.īelow is some code that you can find inside of Electrical’s help as sample LISP code. Look for the line that starts with *WD_OPEN_DWG. "3dface" pt1 pt2 ".You can set a LISP utility to run each time you open a drawing from the Project Manager.

(setq h (getreal "Enter height of wedge: ")) Common LISP provides three logical operators: and, or, and not that operates on Boolean values. Re: Is it possible to use an If-Then-Else Statement in a Field Definitely needs to be on a wish list, any and all of the above, nested field info in dieselexpressions, autolisp fields (as in a field that would allow full lisp programing similiar to the dieselexpression, hmmm lispexpression comes to mind hint hint autodesk), If statements in tables for that matter. (setq h (getreal "Enter height of box: ")) (setq pt1 (getpoint "Pick first corner: ")) One of several expressions or atoms return non-nil Two expressions evaluate to the same valueĪn object is an atom (as opposed to a list)Īll of several expressions or atoms return non-nil Two numeric or string values are not equal There are several functions that return either a T or nil when evaluated.Ī numeric value is greater than or equal to another Once all of the LISP routines have been added to the Startup Suite, click. Since these functions don't return a value the way most functions do, the atom T is used by predicates and logical operators to represents a non-nil or true value. Browse to the location of the LISP file, select it, then click the Open button. Predicates and logical operators are functions that return either true or false. The test expression can be use any function but often you will use two classes of functions called predicates and logical operators.
