Hello: I have a drawing files which originally had its units set to Decimal/Meters. I need to change them to Architectural/inches. I changed the units (Format/Units...), but then everthing that was 1m long is now 1" long. I've been told to scale all the drawing entities, but I would like to know if there is any command that can do this automatically? Thanks |

Hi enemigoman,
To convert from meters to inches you need to scale your drawing down by 0.0254 Then copy it into an architectural/inches drawing. Hope that helps, nameci

Stop! You don't need to do this. Scaling is not what you need to change or Units. You need to change the Dimension style from Metric to Engineering or Architectural. (i.e. Imperial). What you've drawn, on the Model tab is the correct length, all you need to do is effectively measure it in inches not millimetres! The above should do that. |

rossassociates, Is it really? Tell us more about the step how to . I always did the same what nameci did.

I take it you are drawing in the Model tab and then printing from the Layout tab? If you draw a 1000mm line. It is 3' 3" long... i.e. 1 metre. If you then print this off at 1:100 or 1:50 on paper, you would expect it to scale.... I think you may well need to put the multiplier in the alternative dimension style, 0.03937, so that it displays correctly. But if you multiply the linesize in model space and then want to print at 1:100 you will have to zoom at some odd multiplier... I guess it depends on where you want to do the odd multiplier part. For me it seems more sensible, especially if the drawing you have is decimal, to leave the model space at 1:1 and then adjust everything else around it. This means that translating to the Layout space is easily done. Zoom, Scale 1:100 is 1:100 not some other scale... HTH |

You can change the scale in dimension style but that doesnot change the actual length of object if measured. I would still prefer to scale whole drawing as mentioned in earlier post instead of changing the dimension scale.

Hello If you still need that metric unit, just modify your dim styles' alternate units. It will show your meric and english units both on your dimension.
