Importing drawing but scale off by 25.4
Importing drawing but scale off by 25.4
(OP)
Hello
Perhaps someone can advise, is this a bug, a setting or problem to live with.
I make a single line in Adobe Illustrator exactly 1 inch long and export it as a *.DWG. Then open that *.DWG in AutoCAD (2002) the line is now 25.4 inches long. As this is the conversion factor of inches to millimeters it would appear that there is a setting in one of the programs that is wrong.
But, in which program and where would that setting be..... I can work around it now that I know the scale factor.... but still a pain to deal with.
Could someone with Adobe Illustrator and AutoCAd experience please confirm this so I know it is not just "my" system.
Thanks
Ralph

I import the Illustrator.dwg in AC with "_insert". Then I scale the block with "varia". I don't know an automatically tool... maybe tomorrow ...hmmmm ....

Not a big deal, really - just scale the Adobe drawings by 1/25.4 after importing them. Or use the decimal style in dimensioning and add a "mm" suffix.
Autocad does not store it's database in metric, English or Imperial units. It does not care if the thing is 1 inch, angstrom or light year long - to Autocad it is simply 1 unit long.
If I am drawing something that is in metric, I draw in metric and use decimal dimensioning with a "mm" suffix. If I am drawing something in feet and inches, I draw in feet and inches and use the architectural dimension style that adds the feet and inch marks after the value.
