Why importing from other onshape docs convert from mm to inches?

pieri70

Hello
I'm beginning to use OS
I was attempting to copy a public document and then make some mods.
Until today all went fine.
Then I cancelled by mistake a piece and  tried to copy another one from a public document.

My problem is that when I copy the part studio to clipbord an then paste in My document by import function, the part studio is converted to inches...
In my preferences I set mm/deg/gram under preferences.
If I examine the code of my previous parts I can see:

*******************************

FeatureScript 370;

import(path : "onshape/std/geometry.fs", version : "370.0");

annotation { "Default Units" : ["degree", "millimeter", "pound"] }

export function main()

{

    return build();

}

export function build()

{

    const context is Context = newContextWithDefaults(millimeter);
**************************




The part to import code is:

***************************

FeatureScript 370;

import(path : "onshape/std/geometry.fs", version : "370.0");

annotation { "Default Units" : ["degree", "millimeter", "pound"] }

export function main()

{

    return build();

}

export function build()

{

    const context is Context = newContextWithDefaults(millimeter);

    const id is Id = newId();
*****************

Once I import it the code changes to:
********************

FeatureScript 370;

import(path : "onshape/std/geometry.fs", version : "370.0");

annotation { "Default Units" : ["degree", "inch", "pound"] }

export function main()

{

    return build();

}

export function build()

{

    const context is Context = newContextWithDefaults(inch);
************************

Why?????

Then
My document was 80MB, I eliminate almost everything unnecessary and it is as big as it was.
As I eliminate things the dimension rises...
Why???

Thanks

Ok, got it
it was the document units...

But I'm almost sure I didn't change them...

Document units are default inches. Each new document must be changed. Or you can change the default units in your account settings.

Yes I realized this..
But my document was a private copy of a document found in Onshape, and it was originally in millimeters...
And I was making mods in millimeters for a period..

Then at some point OS decided, by itself,  that some pieces imported were in inches..
And all new Part Studios had to be in inches..

For the dimension problem..
I copied/pasted all pieces in a new document and magically the new document went from 80MB to 12MB.
