SW 2008 - Export to dwg/dxf scaling

I just got a bunch of parts from a vendor scaled 1:4. I have been
exporting parts like this for a long time and have never had this
problem before. Here is what SW did:

On the second sheet of my print I had no title block visible and the
sheet scale was set to 1:1. The view the part was on was set to sheet
scale. In the past this would result in a dxf/dwg file 1:1. What
happened is that SW put this view into paper space in dxf/dwg and
scaled it to match the other drawing sheet in the SW file. When opened
in DWGEditor the part measured OK (because it was in paper space) and
I had to really dig to find the setting that told me the part had been
scaled. In addition the other sheet in the SW drawing was in model
space with title block. The result was the vendor burning parts 1/4
actual size. Fortunately there were only 8 parts in the order.

In speaking with the vendor's CAD jocky he has been seeing this
problem from SW in the last little while.

Why wasn't this caught by SW, beta or anybody? When SW starts making
bad parts that is a problem.

Quite the savings on material & processing costs.

 

Thanks for info.

We havent changed to 2008, dont have the time to deal with that many
bugs atm. Will be testing it soon though so info like this is
essential we make lots of stuff based on dxf export and have tried in
older versions that the scale was wrong.

What are you doing to get it to the right scale? Does the scaling come
from the scale on the initial sheet (Sheet 1)? Even if you only save
the sheet which you want the DXF from?

We are doing the same. Making a sheet called "DXF" A4 sheet with no
frame or anything scaled 1:1. And we just save it as DXF and our
workshop load it into their CAM.

 

We just had the same problem after sending a DFX file from Solidworks
to a supplier!

To be fair to Solidworks, there is a popup window, that warns of this
possible error.
Hold on though! How is the programmer/operator ment to know?
Hmmmmm......

How it works:
1, export DXF file
2, email to supplier with a note warning of possible scale errors if
entering straight into cam.
3, supplier's office bod, sends DFX file to programmer/operator,
obmitting the warning note. ( too busy, forgot ect....)
4, programmer/operator enter DFX data into cam, makes cockedup job,
lol

Option 1,
If the DXF is loaded straight into cam, then I think that it is the
programmer/operator's job to check a couple of dimensions, just to be
sure.
"DO NOT SCALE" is the thing to have on any exported or translated
file, as a minimum!

Option 2,
Solidwork's gets their arse into gear and sorts out the hundreds of
cockups in their program.

I think option 1 is the only workable one

 

I'm not seeing the popup.

I checked last night with 2004 and SW used to put a dxf into model
space, not paper space. In my case it put the drawing sheet into model
space and the second, CNC sheet into paper space at the scale of the
sheet in model space. I don't think the pop up (that isn't there)
warns about this.

I have the second sheet go into paper space in 2007. The scaling
problem has been on going for years. 2007 was better and it rarely
happened. I usually open in AutoCAD if it is likely to cause an
error.

Sorry top, to be a bit clearer, the popup window apprears when saving
as a DFX file.

Quote:-

One or more drawing views are scaled differently from the sheet.
Some dimensions translated from these drawing views may appear
out of scale with any new dimensions created in the target system

unquote.

Clear as mud!

lol

 

And this make sense because? For detail parts the second sheet is most
likely going to be the 1:1 CNC geometry. Arrrgh.

Anybody want some really cool paperweights before they rust?
