In my review of AutoCAD 2018, I had this to say about AutoCAD 2018’s changed DWG format:
Why does AutoCAD 2018 need a new DWG format? It probably doesn’t. The 2013 DWG format is capable of holding pretty much anything you want… Although Autodesk cites performance reasons with certain drawings, I strongly suspect the new DWG format was introduced purely to make life difficult for competitors, and to encourage wavering customers to stay with Autodesk for fear of losing compatibility. In other words, it seems likely this is an anti-competitive change rather than a technical one.
In a recent blog post, highly respected Swiss-based Autodesk development and research person Kean Walmsley had this to say on that subject:
The main reason for the break in compatibility is some longer-term work that’s going on inside the AutoCAD codebase. For now this is really only surfacing …
Autodesk’s API guru Kean Walmsley is the second Autodesk person I’ve seen who has been brave enough to stick his head above the parapet by discussing the Cloud, in writing, and in a medium that allows for public comment. Kean has always seemed like a straight shooter to me. Please note that his blog represents his personal opinions rather than an official Autodesk position. He’s after your comments, so please go and let him know what you think on his post. Add your comments here if you’re more comfortable with that, and I’ll make sure Kean sees them.
Thanks to Kean Walmsley’s post on his Through the Interface blog, I have learned something that would have been handy to know for the last decade or so, but which somehow escaped my knowledge. I learned how to increase the size of AutoCAD’s command line history cache. It defaults to 400 lines, which isn’t enough for me. I think this information deserves a wider audience than the ubergeek developers who frequent Kean’s blog, so here goes.
Although it’s not directly mentioned on Kean’s post, you can find the current command line history cache length setting like this:
This will return a value showing the number of command lines AutoCAD remembers, e.g. “400”. Although this is used as an integer value, it is passed to and from the Registry as a string. You can set a new value as shown below. Again, use a string, …
I have been thoroughly enjoying Kean Walmsley’s interview of Autodesk co-founder John Walker, which he has now finished. Kean’s link to part 4 is currently broken (edit: now fixed) and that broken link has been picked up by others (edit: also fixed in Between The Lines), so here are the correct links: Part 1, Part 2, Part 3 and Part 4.
One of the best things about the interview is that it contains some frank criticism of Autodesk (and Microsoft, for that matter). On an Autodesk blog. Think about that. OK, it may be criticism of some stuff that is now ancient history, and it was made by someone who isn’t actually an Autodesk employee any more, but when was the last time you saw even that? It’s refreshing to see just a tiny crack appear in the never-say-anything-negative Autodesk facade.
I remember a …
