Note: That won't change the size of your drawing. You'll have to
SCALE everything in the drawing up by 25.4.

I would say scale the drawing DOWN by 25.4. For example a part that is 25.4 units long would be 1 unit long after scaling.

The scale factor you need to use is 10/254 or 0.0393700787401.

I found the conversion factor online by doing a search, in Google, for converting from mm to inches. If you do the same you'll learn the reasoning behind it.
I recently helped someone in a Canadian architectural firm convert a building drawing they got from a client in Germany. That's where I first came upon it. I did not write it down though so I had to search all over again. So you got your problem solved right? |
