AutoCad XData Organization And Refresher – CadWorx

So I am working with CadWorx. I needed a refresher on my Autocad XData – I suspected that is where the data was stored as CadWorx files seem to have a 3D shape and a line grouped together … but why? Well, the line had XDATA attached to it was my suspicion and I was right. Here are some links that I found helpful to get me re-oriented after 4 years of needing this info …

• XData organization straight from AutoCAD 
  • more (less useful) info on XData
• VBA / ActiveX Starter to get XData
• How to know what registered Apps exist in your file/AutoCad install
  • Whoa – thousands…. How to spit out ACad command line to a log file
  • or do it easily in VBA
• VBA variable types and what >8197 means – it means 8192 + 5 (vbArray + vbDouble)
• Retrieving xData – to take a peek under the hood of a component
