Hi Eric
When I draw full size drawings to send off as DXF files, I draw a 1000 x 100 rectangle on them so that the receiver can check that the drawing has opened at the correct scale (because they don't always).
I have noticed that if I draw a 1000mm line and a 100mm line, then close the file, when I reopen it the 1000mm line is 1000.0015 and the 100mm line is 99.9998mm. Same if I draw a 100mm circle. When I reopen the file it is 100.0002 x 100.0019
The same minor differences occur on scale drawings too.
I know these are tiny tiny amounts and not relevant in practice – but I'm sure earlier version didn't do this. Or am I mistaken??
Best regards
George
