I thought I'd now take a look at the more specific case of defining a command that adds entities into the current pickfirst selection set. Here's some C# code I used to do this, with comments describing its […]

OK, I have to admit I feel a bit cheeky making a separate post out of this one, but then I did promise our friends at TheSwamp that I'd post this additional code, once more provided by Sreekar Devatha in response to an ADN support request. The code is basically the same as that in […]

Jeremy has been in and around the Autodesk family for many years - he actually delivered the first ever ARX training in San Rafael, back when it was still called ARX - and I'm very pleased he chose to […]
