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 ( 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 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.
As a developer, the one thing that is almost as important to me as my development environment is the documentation for the libraries I plan on using. Documentation is broken up into two different pieces of information: reference and concepts.... Continue reading

There is a known issue that is currently being looked into that was fixed in a previous release and has since resurfaced in AutoCAD 2017. There are two known workarounds at the moment to allow debugging with Visual Studio: •Tools > Options > Debug-General > Use Managed Compatibility Mode •Project > Properties > Debug Enable native code debugging Both these options do result in the disabling of Edit & Continue.
I debug my projects without Edit & Continue, mainly because much of what I do is across multiple releases of AutoCAD and versions of VS. I do have the same problem with Edit & Continue though and have reached out to the SWD team. This problem seems to be similar to what was happening with VS2013 and earlier releases of AutoCAD: I will post an update when I get any information to share.
Do you want to affect the direction of the AutoCAD developer documentation? Have comments you want to share with us about the AutoCAD developer documentation? If so, we want to hear from you. A new AutoCAD Developer Documentation survey has... Continue reading

I was able to compile and debug a .NET application without any problems using VS2015 Pro and AutoCAD 2017. The command paused at the breakpoint as expected while the command was executing. So I am not sure what problem you might be encountering, can you share your project settings with me? I am assuming the project compiled fine for an earlier release, if so what release were you targeting before.
Do you have Update 1 installed for Visual Studio 2015? I do know that we don't support Update 1, but think it is simply related to VC++ though. I will look and see if I can identify the problem, but things should work just like they did when debugging an application in VS2012 for AutoCAD 2016. Thanks, Lee
Hello Tharwat, Are you referring to debugging an application in AutoCAD or accessing the developer documentation/XML documentation from inside Visual Studio? Thanks, Lee
Hello Guillaume, I am not aware of any changes to the APIs related to point clouds in AutoCAD 2017, only the general graphic system changes which should improve the performance of point clouds. Thanks, Lee
Hello Alex, I am not aware of any other efforts involving Intellisense for Autodesk desktop APIs other than the work I have done for the AutoCAD Managed .NET libraries. This work and research has only been done within the last few months, so there hasn't been much time to discuss the process I am using to generate the XML files with other groups yet. I do plan on sharing the process with the other teams inside Autodesk, but how the content is currently stored and published is the hurdle along with resources. I will pass the request along to the Inventor/Vault tech pub teams for them to support Intellisense in the future. Sincerely, Lee
Wow, where did the year go! Looking back, the last article I wrote was for the changes in the AutoCAD 2016 APIs and Developer Documentation... I will try to be more active this year. I have been trying to blog... Continue reading

Hello Thomas, I will have to check, but the support page for the book should still be up. The problem with your code exists in two places, " " should simply be "" which represents an Enter. Here is your original code: (command "change" (entlast) " " "p" "c" cnt " ") Here is what the code should be: (command "change" (entlast) "" "p" "c" cnt "") Let me know if you have any further questions. Sincerely, Lee
Last month, Autodesk released the AutoCAD 2016 program and many other products in the 2016 family. Every new release brings with it a variety of features and productivity enhancements, those I covered as a guest author on Ellen Finkelstein's AutoCAD... Continue reading

Writing a book is never an easy task and nor is trying to coordinate multiple books that will eventually be released as a single book. Like any great project, you go in with one vision and often that changes over... Continue reading

I have spent just over 16 years now extending AutoCAD from general customization of the user interface to custom applications written with ObjectARX. Back in 1998 and 1999, I had an opportunity to develop and deliver several AutoCAD customization classes... Continue reading

Hello Rusty, A clickable object model is something that others have requested as well and something that was previously available as you note. As to if or when such a thing might be available, I can't say for sure one way or another. :) Sincerely, Lee
Must be Fall... and someone left the door open. So that means one of two things, I either escaped or a product was recently released. Now time to see if the long Summer days paid off. Some of you might... Continue reading
