Isn't Autocad already full of reactors: i.e. most double click properties? I know I'm not the first to think about mtatts, but it is something I might have more of a need for now than ever. We are restructuring our spec book, which gets rewritten for each job. The designer that is developing the new spec book wants to take it out of excel, which it's currently in (she's cool), and put it in autocad. Attributes won't work because the info is too dynamic, so she's considering mtext. Our project managers are in the habit of copying what's in the excel spec book and creating a shiplist with it. If they don't have the excel version, they have to type out the entire thing. I know how frustrating that can be, so I wanted to make a program that would export the specs itno excel for the PM's.
If you want to covert it to activex, I wouldn't mind, but I've noticed that if objects don't get released, my computer at work slows down to a snails pace. It's probably best to stay away from ActiveX at least on my end.
