lostincad Posted September 16, 2010 Share Posted September 16, 2010 Hey guys I'm about to start working on a project. My boss sent me an AutoCAD floor plan. However it's in inches. I've used the dimension tool to see how big the drawing is and it's in inches. How do i convert it back to MM? Many thanks Tara Quote Link to comment Share on other sites More sharing options...
ReMark Posted September 16, 2010 Share Posted September 16, 2010 To convert inches to millimeters, multiply the number of inches by 25.4 and make sure to set your units to decimal. Quote Link to comment Share on other sites More sharing options...

Hey there ReMark, thank you for helping out again [= aww i was hoping there would be an easier way to do it.. like select all the lines and change the options.. somehow.. i know i'm living in fairy land *sighs* Quote Link to comment Share on other sites More sharing options...
JD Mather Posted September 16, 2010 Share Posted September 16, 2010 an easier way to do it.. like select all the lines and change the options.. . Sounds like your describing Scale to me? Quote Link to comment Share on other sites More sharing options...
lostincad Posted September 16, 2010 Author Share Posted September 16, 2010 Sounds like your describing Scale to me? yes sorry i failed to mention that. Basically the drawing was done in the US, so it's all in inches. My brain doesn't process inches. I only know how to work with millimeters on autocad and as it's a big project i really don't want sit here and work out what the dimension of every line is. any tips on how to make this any easier? Thank you Quote Link to comment Share on other sites More sharing options...

Thanks Hi lostincad, I think ReMark meens that you use the command SCALE then select everything in the drwaing and type the scale 25.4 and it blows the whole drawing op till 25.4 times bigger.

cadvision Posted September 20, 2010 Share Posted September 20, 2010 Scale all (make sure all layers are thawed) x 25.4. Use 0,0 as ref point. Then do zoom extents. Now you will be working in "mm". Other option to start a new drawing using your standard metric DWT and xref or insert the US drawing into your new drawing and scale 25.4 Quote Link to comment Share on other sites More sharing options...
