how to determine the scale of the drawing?

[eldon]

And I am always told how non-confusing the metric system is compared to Imperial.

 

I think there have been more threads sorting out inches, feet, decimal inches, decimal feet, and others that I forget, than sorting out metric units.

 

Metric is simpler because there is only a decimal multiplier. (Ignoring the scientific unit) there three Imperial unit settings (Architectural, Engineering and Fractional) and only one Metric unit setting (Decimal)

 

A bit of common sense on the context of the drawing usually leads to the correct metric unit.

I've problem in determine the dwg drawing with no scale. How could I determine the scale of the .dwg? Because I couldn't ask the person who send me the drawing.

Welcome to CADTutor atiqah.

 

You mention no frame, which makes me think you are talking about linework in modelspace.

You can run the -dwgunits command, which will report the current units of the drawing.

 

Expand your commandline before running the -dwgunits command, to about 10 lines, so you can better understand the wealth of information which will be displayed.

 

Typically, anything drawn in Modelspace should be drawn full scale 1:1.

 

Are you used to working in Imperial or Metric units?

In theory the scale of the drawing should be 1:1. It is generally not a good idea to create a drawing "to scale" as one might do manually on a drafting board. If you can't figure it out on your own attach a copy of the .dwg file to your next post and someone here will take a look at it.

Find a known distance and measure it in AutoCAD, then divide the measured distance by the known distance = scale, you can also use the scale command with the relative option.

Drawing 1:1 is relative to the units used, if the units are not known, then the drawing might still be "scaled".
