I feel it was a waste of time for me to learn the VB Object Model for AutoCAD and SolidWorks. I am a Engineer and Programmer, I currently do consulting for Programming. I tought it was worth the time to learn "VB in CAD". I discovered that it is very Powerful. However I only use AutoCAD/SolidWorks to draft. Very similar to a computer is meant for computing, however there are 'entertainment system' computers. But I much rather buy a seperate computer and entertainment system. ??????
