A question came in on a previous post: Hello, I write applications for Autocad Map and Civil3d platforms, mostly with ObjectARX. I would like to do more with .NET but so far the main reason preventing this is not having the NETUNLOAD command.. With arx I can just arxunload and arxload the application for modifications […]

This is the third part of the series documenting my recent interview with John Walker. Where the first part looked at the early history of the company and the second looked at the architectural evolution of AutoCAD and its APIs, this part focuses on Autodesk's business strategy and focus on its eco-system. I have not […]

The following question came in as a comment on this previous post: Your example above shows how to create a property type filter, how do you add layers to a group type filter (LayerGroup class)? I can create the group filter but can't figure out how to add layers to the group. The filterexpression method […]

Today is a national holiday in Switzerland: the Jeûne Fédéral, or national fasting day (here is some related information), although I have to admit I haven't done anything of the sort. In fact I may just have done the complete opposite. Oh well. I didn't get the chance to put together a technical post for […]

Where the first part looked at the early history of the company, this part focuses more on the architectural evolution of AutoCAD and its APIs. I have not linked to terms previously linked to in the first part of the […]

The question of how to perform a "NETLOAD" programmatically has come in a few times. Well, it turns out the answer - provided by someone in our Engineering team - is refreshingly simple. The NETLOAD command actually has a bare-bones implementation: the hard work of parsing the metadata defining commands etc. is done from an […]

I'm still a little frazzled after transcribing the 18,000 word interview with John Walker (and largely with two fingers - at such times the fact that I've never learned to touch-type is a significant cause of frustration, as you might imagine). I'm also attending meetings all this coming week, so I've gone for the cheap […]

On Thursday of last week (September 4th, 2008, for those people accessing this post sometime in the distant future :-), I had the great honour of meeting with John Walker, one of Autodesk's founders and its former CEO. I've known for some time that John lives in the Neuchâtel area, and it turns out he […]

Now for something I hinted at in this previous post... I'm very happy to announce that Through the Interface has two new siblings: Mod the Machine is a blog devoted to developers working with Autodesk Inventor and is written by Brian Ekins, Inventor API designer. The Building Coder is a blog devoted to developers working […]

This is an interesting one that came up recently during an internal discussion: During my module's Initialize() function, I want to decide that the module should not actually be loaded. How can I accomplish that? The answer is surprisingly simple: if you throw an exception during the function, AutoCAD's NETLOAD mechanism will stop loading the […]
