First you have to have the Scale set properly in Document Properties. For units in mm, that Scale should be set to 3.77953.
You might have to either re-draw the rectangle, or scale it to the proper size, after making that change.
If that was not the problem, or if you still have the wrong size results after making those changes, we'll need to investigate further. Possibly the native resolution of Inkscape and the software where you're using the DXF image could be different. Or maybe something else. But one step at a time.
Before you imported the DXF, did you check the rectangle was the right size, after changing the scale? Because if the scale was different than 3.77953 when you created the rectangle, the rectangle probably changed size and needs to be fixed.
Here's the routine:
set the Scale properly (as you did)
make sure the rectangle is still the right size, and if not, fix it
either save a new DXF file, or overwrite the first one
Now when you open the DXF file in Inkscape, it should be the same size as when you saved it.
Oh, actually I see that's not really a rectangle. But you can still scale it if necessary. You should not have to draw it again. (I just suggested re-drawing because a rectangle is very fast to draw.)
BTW how do save properties like scale to be default?
Set the document properties to the desired values, then save as default.svg to your user templates file: C:/Users/your-username/AppData/Roaming/Inkscape/Templates.
Ok, let's make sure we're both doing the same thing. I see you're using 1.0 beta.
When you save the DXF file, are you using DXF12 or DXF14 ? If using 14, do you choose ROBO-Master or LWPOLYLINE option, or both or neither?
Are you opening or importing back into Inkscape? Or into some other software?
Using 12, opening my DXF file in Inkscape, it appears to be blank. There are no objects visible or selectable. Using 14 (neither ROBO or LWPOLYLINE checked on save), it saves the paths of the rectangle, but they aren't connected. They are just 4 paths in the shape of a rectangle. Notably, whether I use Manual Scale or Read from File, the rectangular paths are 4 times larger than the original rectangle! (A 2nd test with a star shape, the paths in the DXF file are approx 7 times larger than the original!)
Note that I'm using px, but I don't think that should matter for this test. So unless there's something fundamental about DXF that I don't understand, this would be unexpected, and possibly a bug.
For comparison and testing, would you please share either your SVG or DXF file? Or even both, if you saved an SVG?

Inkscape's native unit is mm. So to make sure the Scale is set properly, you don't need to do anything to keep it that way. But if there are other things you want to customize in your default, you can make either a custom default document or a special template. (Those are almost the same thing.)

Maren or anyone else following this. Should this be reported for 1.0 beta? Or is it already known?
I have not searched, because I'm confused exactly where to search in GL. I know about the Inbox account. But after some time, bugs are moved to Issues somewhere else, and I'm not sure where that is.
The problem hasn't been described with enough detail yet to know whether it's a bug or not. Could be just a different default template - or could be the dxf import extension being broken in some way. What we'd need first would be a step-by-step description of how to reproduce this. Then we'd need to actually be able to reproduce it, to exclude any local reasons.
Confirmed, dxf 12 is empty, dxf 14 changes the square's size (in my case, using mm and 'read from file', it was shrunk) and moves it to a different place.
I would not expect DXF r12 to have a readable scale; $MEASUREMENT is not part of the spec for that dxf version. (spec attached below)
DXF is regularly regarded as a unitless format. That said, the file headers can carry some unit and scale information, but it can vary from version to version.
I suggest testing import/export workflows that provide reliable results with the other software being used.
LibreCad edits DXF natively and has a few choices of DXF version to save-as, so it can be helpful for conversion.
If there is an Inkscape "native unit", it would be the "user unit", which has a 1:1 scale relationship with the SVG standard pixel, which is set currently at 96/in.
- also, the reason that DXF 12 sometimes returns an empty file is because it does not support the <rect> tag or the <circle> tag, it only supports the <path> tag.

Aaahh, that explains my confusing results!
Will have to try and remember that for the future. But unfortunately, probably won't remember 🤔
Beginners' Questions export SVG to DXF with dimension?
Inkscape.org
Hi
I created svg file (recatngle 100X200 mm)
Saved as DXF
And then import the DXF with the option of read scale from file, but the imported one is different dimetions (very small)
How can I maintain the dimentions?

for first note, I changed the scale to be 3.77953 (is it as attached?)
I tried then importing xdf to same inkscape, but I get smaller image (see attached)

I changed scale in SVG and needed to change the rectangle size
I overwritten teh DXF
I opened new document, changed scale and then imported DXF, still small
BTW how do save properties like scale to be default?
Set the document properties to the desired values, then save as default.svg to your user templates file: C:/Users/your-username/AppData/Roaming/Inkscape/Templates.
Here is a round-trip: Inkscape>DXF>Inkscape.

cheers
I think there is less point in trying to resolve issues when using beta version.
I wil revert to official realse
i n official release all working well
Ok, that sounds like good news for now!

Using 1.0beta2 (1.0beta2 (1c3732b, 2019-12-09)) on Windows 7 Pro, 64-bit and attached dxftest.svg
When I tested the other day, I had different results for DXF 12. But now, I get the same results for both DXF 12 and 14.
Confirmed, dxf 12 is empty, dxf 14 changes the square's size (in my case, using mm and 'read from file', it was shrunk) and moves it to a different place.
I'll make a bug report.

for the Inkscape 1.1-dev branch, a patch has been applied to make it compatible with Inkscape 0.92.4.
see https://gitlab.com/inkscape/extensions/issues/174
and https://gitlab.com/inkscape/extensions/commit/959619d12736c9742b7b2dc175b85fffd30ae269
the code for the 1.1beta branch has been modified again to make the scaling compatible with 0.92.4.
if you are using this branch, please re-test using the latest extension code at:
https://gitlab.com/inkscape/extensions/
- also, the reason that DXF 12 sometimes returns an empty file is because it does not support the <rect> tag or the <circle> tag, it only supports the <path> tag.
Aaahh, that explains my confusing results!

I guess it would make sense to either auto-convert those elements or to warn the user.
if font utf-8, all ok,
@volatile Bug report link is https://inkscape.org/report - the forum will not be useful for bug reports.
@volatile, it is not clear if there is a stroke on the Inkscape object, and/or if the bounding box is set to "visible".
Please share the Inkscape svg file or a complete screenshot.
