unit problems

Anonymous

Hello,

I have got a problem with my autocad. I have constantly that my numbers are in a weird unit. Everywhere where i look, the units, setting its always in milimeters but it doesn’t do it in milimeters when i want to make a square or something it constantly gives this same unit. U can see in the screenshot under the units.

It should be in millimeter but it is not. We checked the units and its all in millimeter and in decimal can someone help me with this problem?

Try -dwgunits and choose mm, or you should use metric template when start a new drawing.

Hi,

 

You have the units set to the millimeter, but you are drawing at a very far distance from UCS. 

Try this:

Delete everything from drawing and then type in the command "REC" and then specify the first corner "0,0" and press enter and then specify the other corner "200,200". Next type in the command "ZOOM" and then press "E" enter. Now you would see the RECTANGLE close the UCS. You can now draw the rectangle and you would not see that Exponential power near the cursor(E+17)🙂

@vinodkl is correct that you are drawing very far from the origin.  To elaborate:

 

The "weird unit" is scientific notation2.1E+17 mean 2.1 times 10 to the 17th power  drawing units from the drawing origin of 0,0.  [The E stands for the Exponent that 10 is raised to.]

 

The distance from the Sun to the Earth is "only" about 150 million km, or converted to millimeters and in AutoCAD's version of scientific notation, about 1.5E+14 drawing units.  So where you're drawing is [if my quickie calculation is correct] roughly 1400 times the distance from the Sun to the Earth.  That can cause all kinds of difficulties in drawing.  Move close(r) to the origin.

 

And see if you can determine why or how you've gotten way out there.  Do your drawing template files have you starting beyond the solar system?
