Re: [PSUBS-MAILIST] OSS
DXF ist the standard worldwide - and the OSS is for homebuilders .
- how much of them have CAD system in 3D quality ?
- most cutting machines for plates need 2D DXF information
- At this small project there is no need for 3D.. but 3D keep
out to many people -like me..
regards Carsten
