What is going on, I have been sent a .dxf file from Autocad by a friend, he is drawing up the same structure as myself.
I am working in inches, as it was built in inches, he is working in cm ( ! )
I open the file using Rhino V5, I leave the two boxes in options as centimetres, it opens, I measure a brick on its long side (I know those in use were 8.75inch) and dims have it as 0.22
So I try again, altering the two boxes (layout and model) to millimetres.
I select that and copy paste it into my project and I cant even see it, zoom selected and there it is, a fraction of a brick in size !
When sent a previous .dxf a day or two ago, I went Rhino>open file, entered inches and it came in somewhat smaller, I then repeated with centimetres and it came in same size as my structure. Once open I look in Properties: units centimetres, dim style iso-25 brick 21.5cm , (my maths says 8.4646inch)
Yet today its not doing that.
I have just realised why, this file for some reason he is working in metres !
Should not the dxf know the units of measurement in use and display that in the open dialog box ?
(Now to fathom out why bricks are 22cm and not 21cm !)
