Why is ther no way to save to earlier versions of TC. Why have the ability to convert to older versions of AutoCAD but not TurboCAD? It makes no sense to me. IMSI used to have a conversion utility, many many moons ago. If it is not going to be incorporated into the program then please provide us with a conversion program. It would be very helpful for exchanging files. Or is there a way to set .dwg as the default file extension. Those files can be saved back to v14?
