risberg Posted December 13, 2011 Share Posted December 13, 2011 I recieved a drawing in which the coordinate values are a thousand times too high; they are in millimeters and I need them in meters. I checked the settings of the drawing, and it clearly says that it´s in millimeters, but it doesn't help to change the setting or to copy the whole drawing into a new file with meter settings. Does anyone know how I can change the coordinates to meters? Quote Link to comment Share on other sites More sharing options...
sparkyuk Posted December 13, 2011 Share Posted December 13, 2011 (edited) Are you saying its incorrectly scaled in model space or paper space ? if so below will fix it The easiest way is by scaling all objects in the AutoCAD drawing. if you receive a drawing in mm, you can convert it to metres by selecting all the object's, and scale them by 0.001 (or 1/1000). To keep the drawing origin you use 0,0 as the base point. Command: scale Select objects: ALL Specify base point: 0,0 Specify scale factor or [Copy/Reference]: 0.001 Edited December 13, 2011 by sparkyuk added found solution i hope Quote Link to comment Share on other sites More sharing options...
Tiger Posted December 13, 2011 Share Posted December 13, 2011 If you use the drawing as an X-ref then you can change the scale when you insert the file - or by highlighting the X-ref and bringing up the PRoperties-window. Quote Link to comment Share on other sites More sharing options...
AlinOz Posted December 14, 2011 Share Posted December 14, 2011 There is another option available too... Unfortunately, not everyone behaves themselves when they produce their drawings, so no promises here. If the original drawing has its units set to millimeters and you set up your drawing units to metres, if you insert their drawing as a block, it should automatically resize it according to your units. After it is in there as a block, you can explode it to return it to individual objects you can work on. This is a feature built in to AutoCAD and if someone like me in good old Metric Australia gets a block from dear old Imperial (well half) USA, I should be able to just insert it into my drawing and it will automatically scale up 25.4 times... Well that's all well intheory, but 99.9% of the time, these drawings show up as 'Unitless'... If it has the units set correctly, all should work fine and dandy Quote Link to comment Share on other sites More sharing options...

karim el said Posted February 22, 2016 Share Posted February 22, 2016 but when i scaled my drawing all my dimension got distorted any advice Quote Link to comment Share on other sites More sharing options...
SLW210 Posted February 23, 2016 Share Posted February 23, 2016 Try using -dwgunits (notice use of the hyphen) instead of scaling. Quote Link to comment Share on other sites More sharing options...
