We people are doing the Autocad CAD customization using COM & .NET API.
Now I have heard that we can read or write thedwg file using realdwg toolkit without installing AuotCAD on my machine so it is beneficial that we can do without AutoCAD.
Rather than this advantage, how it can be usefult to our team if our organization will but it ?
"How it can be useful" totally depends on what you/your organization needs to do.
If your main focus is "AutoCAD customization", then you do not need RealDwg, as you already know that one can use it to deal with DWG file WITHOUT AutoCAD being installed (hence no need for AutoCAD customization).
