Hello Kerry, I did some initial testing with the Integrated ObjectARX 2023 Help installer for VS2019 and it should work with VS2022 as well. The only thing that I noticed at the moment is that you will need to update your VS2022 installer to include the Help Viewer which can be found on the Individual Components tab. Once installed, you should be able to run the Integrated ObjectARX 2023 Help installer as it is only looking for the installed location of MS Help Viewer 2.3 in order to merge the help files into the correct Content Store. Let me know if this works for you or not. Further testing will need to be done before making any official release of the installer. Sincerely, Lee

Running is a great way to increase new brain cells; exactly what might be helpful to retain all the great information from AU sessions. :) https://www.verywellmind.com/adult-neurogenesis-can-we-grow-new-brain-cells-2794885

Without a specific use case to design the sample code around, quickly created a very generic example that could be refined a number of ways. The sample code looks for text the text value of "123" and if found, it will change the Visibility State of blocks named "Trees - Imperial". I built the example around Single-line and Multiline text, but it could be done for block attribute values as well. Good luck and let me know if you have any specific questions. ;; Looks for text objects with 123 in them, and if it finds the dynmaic block ;; "Trees - Imperial" it changes the visibility state to Shrub (Plan). (defun c:blockFlip ( / ssAll nCnt nTextPos lBlocks lText oEnt lEd sTextCompare) (setq ssAll (ssget "X") nCnt 0 nTextPos nil lBlockRefs nil lTextObjs nil sTextCompare "123" ) ;; Step through all objects in a drawing and look for the text objects and block references (while (> (sslength ssAll) nCnt) (setq oEnt (ssname ssAll nCnt) lEd (entget oEnt) ) ;; Create two lists; one with text objects (single-line and multiline) and one with block references ;; Note: Could have also done multiple (ssget) statements with a filter (cond ((or (= (cdr (assoc 0 lEd)) "TEXT")(= (cdr (assoc 0 lEd)) "MTEXT")) (if (= lTextObjs nil) (setq lTextObjs (append (list oEnt))) (setq lTextObjs (append lTextObjs (list oEnt))) ) ) ((= (cdr (assoc 0 lEd)) "INSERT") (if (= lBlockRefs nil) (setq lBlockRefs (append (list oEnt))) (setq lBlockRefs (append lBlockRefs (list oEnt))) ) ) ) (setq nCnt (1+ nCnt)) ) ;; Step through all text objects and look for text strings that match the value of sTextCompare (foreach oEnt lTextObjs (progn (setq lEd (entget oEnt)) (if (= (cdr (assoc 0 lEd)) "TEXT") (setq nTextPos (vl-string-search sTextCompare (strcase (getpropertyvalue oEnt "TextString")))) (setq nTextPos (vl-string-search sTextCompare (strcase (getpropertyvalue oEnt "Text")))) ) ;; If a match to text string was found, step through the blocks (if (/= nTextPos nil) ;; If the block is named "Trees - Imperial" one of the sample dynamic block son the tool palette ;; and the block is indeed a dynamic block, change its viibility style (if (and (= (getpropertyvalue ent "BlockTableRecord/Name") "Trees - Imperial") (= (getpropertyvalue ent "IsDynamicBlock") 1) ) (progn (setq lDynProps (vlax-safearray->list (vlax-variant-value oDynProps))) (foreach oDynProp lDynProps (vla-put-Value oDynProp "Shrub (Plan)") ) ) ) ) ) ) (princ) )

The DATALINK object isn't documented currently in the DXF Reference, the requests to document this information comes from the team that implements the feature. The Datalink feature pre-dates my time as the AutoCAD API Writer, so I don't want to speculate why it wasn't documented. I will add this to my list of things to look into for a future update, no promises as to when it might be documented though. DATALINK objects are stored in the "ACAD_DATALINK" named dictionary and can be obtained with the DICTSEARCH AutoLISP function among other APIs. (dictsearch (namedobjdict) "ACAD_DATALINK") Once you have the entity name of the "ACAD_DATALINK" dictionary, you can then get the Datalinks that are defined in the drawing. (entget (cdr (assoc 360 (dictsearch (namedobjdict) "ACAD_DATALINK" T)))) ((-1 . ) (0 . "DATALINK") (5 . "203") (102 . "{ACAD_REACTORS") (330 . ) (102 . "}") (330 . ) (100 . "AcDbDataLink") (1 .

Hello Gareth, The AutoCAD Map 2017 ObjectARX SDK has been posted to the URL you mentioned; my understanding is only 64-bit is supported even though the page lists both 32- and 64-bit. I might be wrong as I was parsing the email rather quickly. Thanks for bringing this to my attention, even though it wasn't doc, I am always happy to communicate issues onto others when I can. Sincerely, Lee

I am not aware as to why the AutoCAD Map 2017 Object SDK hasn't been posted yet to the site. I did send an email about this issue, but will not hear much other than maybe a reply as to why I am sending emails during my sabbatical. :) If I hear anything, I will add a new comment.

Sorry about the delay... I am currently on sabbatical, I will try and take a look at this tonight. You might have to get the actual MText object in the cell and change its color directly.

I inquired about the ObjectARX 2017 Wizard 3-4 weeks ago and there was some talk in updating it, but a technical problem was encountered to my understanding and that is why there was a new version created for Managed .NET and not ObjectARX. The code for the ObjectARX Wizard is on GitHub (https://github.com/Developer-Autodesk/ObjectARX-Wizards) if you want to try and make the changes yourself. I am sure once the new one has been built though, it will be posted with the others at http://www.autodesk.com/developautocad. I will do some following up on the wizard if the new one hasn't been posted by the time I get back from sabbatical.
