Recently Autodesk Infrastructure Design Suite became available and I'm assuming you all got a "nudge" from your reseller to opt in before the deadline. After getting the low-down it really seemed like a no-brainer to me. A whole lotta software for not a whole lot more $$. With IDS Premium we now have a matching license of NavisWorks Simulate and 3DS Max to go along with our Civil 3D licenses. Of course the Autodesk website lists a bunch of other stuff but when it comes down to it, if you're a Civil 3D customer on subscription, you're already getting all of that except the Navis and 3DS Max.
So why did I post this? Well, to let you know it's a good deal...if it is. Or to have folks out there tell me (and the rest of us) that I'm missing something...if I did. Feel free to provide a comment to help us all feel more at ease about the decision to opt in.
