Unit problem when exporting DWG

Rhino
1

Hi,

I am having problems when exporting to DWG.
Everything in my rhino file is setup to meters.

But the dwg files i create in rhino always get setup to millimeters when i open them in autocad.
The result is that i have to manually open each exported file in autocad and manually change units to meters.

Is there a fix to this ?

Thanks,
Chears

Hi Raouf,

Rhino has a very complete list of unit types that select for your model.
AutoCAD has units: Architectural, Decimal, Engineering, Fractional and Scientific.
Decimal is unitless while the Architectural format assumes inches is the base unit.
Because of these difference, you will have less work, if you model in mm in Rhino.

This FAQ article is written for the feet to inch issue.
You can apply it to the meter to mm issue that you are experiencing.

Hi,

thanks for your answer.
But i’m afraid it does not solve the problem. I have already tried it and wether the units setup the exported DWG will always be in millimeters when opened in autocad.

Wich is not possible when working with diffeent contractants and companies that require dwg files in meters.

Hi,
I have the same issue with exports from Rhino 8 to Autocad DWG.
Did you find any solution for this?

Thank you.

Hi, for now we just convert the units once in autocad… No solution for this and it causes huge interoperability prblems since dwg still is the most common format

Hi @raoufdjema15 ,

Help me understand your issue better.
Please send mary@mcneel.com:

  1. small 3DM file
  2. also end me the DWG that you exported as well.
  3. send any marked up images and details that will show us what is not working for you once you get to AutoCAD.
  4. Also send your SystemInfo: open Rhino, type SystemInfo command. You can paste it here or email it to me.

Make sure and reference this thread in your email.
I will see if I can think of any thing that will help.
There may not be, but I want to see a file that does not work for you.

Thanks,
Mary Ann Fugier
