In earlier versions up to 5.2 COADE had kept dwg interface, the complete model can be taken to Autocad using dxf output it gives.

But this option is removed after 5.2, don't understand the reason.

I also find, the newer versions are getting more useful only for the SP3d users. There is no greater addition since version 5.0, I will personally rate version 5 is the most stable version of CAESAR.

The present versions I find more trouble, sometimes even opening a file.
