AutoCAD Visual LISP / AutoLISP :: Search Database / Tables To Determine If New Layers Present In Drawing
Dec 6, 2013
Is there a way to search the database/tables/whatever to determine if new layers are present in a drawing?
I want to run a script to reconcile new layers in the sheet drawings after having cleaned the xref drawings, and the script bombs if there are no new layers present in the parent drawing.
If I could determine what triggers the layereval/layernotify sequence (tblsearch?) I could include an if or while lisp routine that would invoke the layer command and then reconcile the new layers.
I'm new to working with scripts and have played with it a little bit but my knowledge is severly lacking, I picked up script pro and have had some success batching simple commands.
What I have is a large database with differing layer convensions that I want be able to run a script that will open rename layers save and close, the layers are not of the same name but similar enough that I could set peramiters for less then a duzon layer names and catch my target then rename it to a standard, for example "A-wall exterior" to "A-WL-EXT", a simple enough command but within the database the "A-wall exterior" could be one of a duzon simmilar names.
My thought was to run the -rename la "layername" "layername" qsave script but when the original layer is not found it gets stuck untill script pro times out and fails. If there is some way to search out names and once found rename that would work.
Is there a way to apply a single string value "Phase1", or "Phase2" to all layers in a drawing? I though about exporting a Layer State, modifying it in Excel, then re-importing the layer state, but, Layer States don't store a value for "Description."
I'm creating a consolidated map from several drawings, but I'd like to be able to separate the layers from each drawing. Description seems like a good value to populate and be able to sort by in the Layer Manager.
I have a specific need to determine if an entity is existing or not so that I can either make changes to or create the entity. I'm trying to do this while referring to the entity by it's handle. Below is my code this far but it doesn't work.
(IF (AND (SETQ HNDL (VLAX-LDATA-GET "TB" (STRCAT PLN "PLAN"))) (NOT (VLAX-ERASED-P (VLAX-ENAME->VLA-OBJECT (HANDENT HNDL)))) ) (PROGN ;;| DO SOMETHING WITH THE EXISTING ENTITY ) (PROGN ;;| MAKE THE ENTITY (vlax-ldata-put "TB" (strcat PLN "PLAN") (CDR (ASSOC 5 (entget (entlast))))) ))
I ran the program and the handle was stored, then I deleted the entity and ran the code again and this is the error I get:
; error: unable to get ObjectID: nil
This VLISP stuff sometime has unpredictable hoops to jump through first, so I wondering if this is the case here.
I create tables in Excel, then paste into AutoCAD as "AutoCAD Entities". Works great. However, once the table is in the drawing file, I have to manually set the font, text size, text alignment, etc.
Been trying to use AutoLisp to facilitate this process without success.
(if (ssget "_X" '((0 . "ACAD_TABLE")(1 . "PIPE LIST")))(progn (vlax-for a (setq ss (vla-get-ActiveSelectionSet (vla-get-ActiveDocument (vlax-get-acad-object)))) (repeat (setq r (vla-get-rows a))(setq r (1- r) c -1)(repeat (vla-get-columns a) (if (eq "*PL*" (vlax-invoke a 'GetText r (setq c (1+ c)))) (vlax-invoke a 'SetText r c "THREAD ONE END"))))) (vla-delete ss)));progn);if
Basically, it replaces this text inside a table:
1 1/2" NPTM - A53 - 3000LB - A-53 - 3000 LB
with:
thread both ends.
But I'm limited to the size of pipe, it's material and its pressure rating. I can't change how the text in the field is populated. It would be nice if, it did a search for NPTM, and when that string exists in the string, change it to "thread both ends".
Essentially right now, I have 46 lines (and growing) of different scenarios. I just want the NPTM to trigger the string change.
Is there a way to determine the type of ACAD object that the user selected? I need to retrieve the value from either a dimension or text. The info could be in either format so the lisp routine needs to determine what was selected so the correct vla-get command is used.
Once I determine what the object is I can use an if statement to retrieve the value.
;user selects the object (setq dimobj (vlax-ename->vla-object(car(entsel)))) ;If ACAD object is a dimension do this. (setq dimvalue (vla-get-textoverride dimobj)) ;If ACAD object is text do this. (setq dimvalue (vla-get-textstring dimobj))
any code that can search for a layer using wildcards?
In my specific case, I have multiple layers than begin with "MECA" followed by a job code. I'm trying to code something that will check to see which of those layers is on, then return the layer name.
I'm trying to get the file name of a file outside the search path. Obviously (findfile) is not an option. The file location changes with each project so adding a search path is also not an option. I can get the path to the file but i can't seem to figure out how to get the file name. I can also get the first set of characters, as they are constant from project to project, it's just the end of the file name that changes. The file is always a PDF.
I'm using a Lisp which searches a certain folder and then updates all blocks, which are nested in that folder.
My issue is, that I'd like to use more than one folder on different path, where the LISP can search for this files. Is there a way to use multiple search path?
The code I'm using now to search for the blocks is: (setq dir "I:\AutoCAD Blöcke\Template\Support")
1) I want to search the drawing for the pre-define block names given in the program. 2) If the are there, I want to replace them with the new version. 3) Program replaces the first block it finds, then tries to insert that block.
Say I have 2 items, one is on layer "M-Duct" and the other on "M-Pipe" (they are in the same drawing). Any lisp routine that would create the layers "M-Duct-New" and "M-Pipe-New" (based on the same color and LT as the original layers) and then move those objects to the newly created layers?
I would like to save the data generated by LISP program at command prompt area to any data base app or any simillar app from where I can retrieve the stored data again in autocad for further usage.
For example, A LISP program generate the result as shown in above Fig. I would like to save the data of step 5, "Shear force in tonnage is : 50.868" to any database application or any simillar one from where I can retrieve the stores data for further usage.
I would like to create a lisp program that check the attributes of block using an external database, if tag1+tag2+tag3 = XXYYYYYYZZZZZZZZ ok end program, if not make a circle on block :
My goal is to have a quantity count of a specific dynamic blocks visibility state and for it to be updated when changes are made, without having to recreate the Table. I want the total amount to be where I have the Fields.
My test drawing is the perfect example, assuming I have all the items that I need in the drawing. I don't want to recreate the Table and re-link each Field to the appropriate cells of the table. Which no one wants to do. In this test drawing the objects in Blue will be used in the final production drawing.
I noticed if I add a new item or remove an item entirely I'll have to redo the Table and fields. Which defeats the time I'm trying to save.
I have a database with the polyline reference/handle (i.e. '13EE6A') and each polyline has a 'door number' associated with it.
I can easily create a query that produces a table of polyline ref and associated door number.
I need to somehow import that door number into the middle of each polyline on the drawing - i.e. if there is a polyline with that handle, put the associated door number in the middle of the polyline on a certain layer. I do NOT need an active link between the database and drawing - it's just to initially populate several thousand rooms numbers!
I used this snip it to add the path for network tool palettes. It works but it keeps adding the same search path every time i open a new session of AutoCAD. The list keeps getting longer with the same information. Say you want to make sure your users all have a certain tool palette.
I have a simple lisp routine that loads everytime one of my users opens a new drawing, It sets the printer paths, sets the template paths and sets a bunch of environment variables
One thing I would like to add to this lisp routine is the ability to add support file search paths.
Is there a simple setenv variable for this? or is it more complicated?
I am trying to put together a lisp routine for exporting a Civil3D drawing to basic autocad entities and convert it to a clients layer standards.
I don't want any user input, so I see two problems with the routine at the moment.
Step 2. SAVEAS - I want the drawing to be saved in the same directory as the current drawing, either called "CLIENT_export.dwg" or preferably "Export_{current drawing name}.dwg". If the dwg exists I want it either to overwrite or increment a suffix number.
Step 4. At the moment it askes the user for a selection, I want it to select "ALL"
;;;Purpose to convert a Civil3D drawing into CLIENT layer standards.
but I have more than 150 dwg file and I should open all of dwgs one by one and setting ON/OFF for STAMP layer for every drawing and it takes so much time!
I just want to select files and LISP program set the STAMP layer to ON or OFF value.
I am running a simple script to color some layers in XRefs. I need to colour all layers in XRef files that don't have part of their name containing the characters NWP and I can do this with the line
-layer c 32 ~*|*NWP*
but then all the layers in the sheet file (not in Xrefs) also turn to 32 which I do not want. Is there some way to include an "except" statement in scripts.
I'm trying to set up an easy way to import layers from a certain dwt. file with a shortcut.
Now I found this code, which kind of works, but doesn't do the whole trick. It works with a Popup where I have to insert the dwt. file. It's also annoying that it opens this file than and I have to close it manually.
I would like to have this without any import options and automatically takes this one file always for the layers.
How to edit this string so that it would change ONLY XREF layers in a dwg. to color 3 bylayer, and leave all of my additional layers in the current dwg. as is.
What the require setting to enable me to lock of several layer continuously when i click the "LAYER OFF" button at the toolbar? I wish to set to be like whenever i use the "LAYER OFF" command, i can direct just continue to click several layers for it to be turn off.
