zipper Posted September 15, 2009 Share Posted September 15, 2009 Hi everyone, I need to draw a flange which has to be cut out at an engineering shop, its a basic shape and easy to draw. Now here is my problem: I need to draw in mm, as the measurments I have are in mm. I do know that autocad doesnt see mm/inches/cm etc...it just sees units, from my research, it states that I have to tell autocad that I want 1mm to equal 1 unit...but I cannot get it right.. I was told to goto to the dimension tab=> dimension style => modify => primary units and then type 25.4 in the scale factor box...so I did it.....and re-drew my whole drawing...then after I printed it, the measurments on the paper was incorrect! Its frustrating, confusing and the more I research about it, the confusing its getting Can someone please help me by giving me a full explanation on how to take my measurments I have (which is in mm), draw it on autocad, and then print it onto a A4 piece of paper in 1:1 scale... Please, please I really need the help Quote Link to comment Share on other sites More sharing options...
cedwards Posted September 15, 2009 Share Posted September 15, 2009 Go to Format>>Units or just type units in the commandline Change the type to "Engineering" Change the insertion scale to "Millimeter" Then everything you draw will be in mm Quote Link to comment Share on other sites More sharing options...
zipper Posted September 15, 2009 Author Share Posted September 15, 2009 Thanks for your response! But its still not working :-( Let me explain to you what I did from the very beginning: I open up AutoCAD2007; i then went to file=> new; I then opened "acad"; then went to Format=>units; changed it to "Engineering" and changed the insertion scale to millimeters; I then drew a line of 10 units; printed it; after measureing it with my ruler, the line is 24mm (not 10mm) So what am I doing wrong?

JD Mather Posted September 15, 2009 Share Posted September 15, 2009 File New and select Metric template or Open new metric without template. Quote Link to comment Share on other sites More sharing options...
chelsea1307 Posted September 15, 2009 Share Posted September 15, 2009 did you plot to scale? Quote Link to comment Share on other sites More sharing options...

Did you dimension the line in CAD? What result did you get? Your problem might be in the way you printed... Quote Link to comment Share on other sites More sharing options...
cedwards Posted September 15, 2009 Share Posted September 15, 2009 Well I'm amusing you are plotting to a 8.5x11. when you plot change the plot scale to 1:1 Quote Link to comment Share on other sites More sharing options...
nukecad Posted September 16, 2009 Share Posted September 16, 2009 Are you plotting at 1:1 or Scale to Fit? By the way; if anyone is looking for metric drawing templates I posted a full set at this link- http://www.autocadeverything.com/help/showthread.php?t=4380&highlight=templates Quote Link to comment Share on other sites More sharing options...
