Tiger Posted October 17, 2012 Share Posted October 17, 2012 If you want to draw in meters, you change the Units to Meters (type UNITS to open the Units dialogue box) and then you draw in meters. Or change it to centimeters. Or whatever you like. One thing to keep in mind though, is that if you change UNITS, that doesn't affect what you have aldready drawn. You can't use Units to scale your objects from millimeters to meters. The Units-command controls how AutoCAD scales content (blocks and externals references) that you insert in your drawing.

ReMark Posted October 17, 2012 Share Posted October 17, 2012 Have you seen this tutorial re: Units and Scales? http://www.cadtutor.net/tutorials/autocad/units-and-scales.php The only way I know that you can specify the units (mm, cm or m) you are drawing in is via the -DWGUNITS command. There you can select from the three most common metric units (millimeters, centimeters and meters) as well as imperial units. Type the command at the Command Line and follow the prompts. This is what you will see: Drawing units: 1. Inches 2. Feet 3. Millimeters 4. Centimeters 5. Decimeters 6. Meters Unit for length : 4 Drawing unit display formats: 1. Scientific 2. Decimal Linear display format : accept the default Linear display precision : accept the default Scale objects from other drawings upon insert? [Yes/No] : accept the default Match INSUNITS to drawing units? [Yes/No] : accept the default ** WARNING: you have changed the unit for this drawing database. ** ** All new objects will be drawn according to the new unit, but ** ** existing objects will not change size unless you specifically ** ** ask to have automatic scaling occur. ** Scale objects in current drawing to reflect change in units? [Yes/No] : in an empty drawing this is of no consequence Quote Link to comment Share on other sites More sharing options...
rkent Posted October 17, 2012 Share Posted October 17, 2012 If you are in a blank drawing then simply use UNITS command, set Length to Decimal. Now when you draw you will be thinking in mm or Meters, just as the tutorial talks about, see Remark's post with the link. That is it, change to Decimal, draw in the unit you want. Enter 1 unit for a line length and it is a mm, or it can be 1 Meter, but not both in the same drawing. In a drawing assumed to be mm then if a meter is needed you will input 1000 in a command, if the unit is Meters then you will input 1 in a command for 1 meter. Plot scales will be vastly different depending on which unit you are assuming for your drawing as title blocks in a layout will be in mm regardless of your model space assumed unit of mm or M. Text height will be set depending on whether your drawing is mm or M, and whether or not you are using Annotative scaling. Ditto for dimstyles.
