Scaling when saved to dxf/dwg

I know this question has come up many times, but mine is very specific.

I am trying to save a drawing to dxf/dwg, but the scale is coming out EXACTLY THREE times larger.

So if a tank has a 10 ft diameter, the e-drawings measurement shows it as 30 ft.

I have tried all the usual methods and options (scaling, etc.), and it ALWAYS comes out to exactly three times larger.

The funny thing is - this only happens when I try to convert large layouts.

When I convert small parts, the scale is correct.

Also - this only happened after I switched to 2015. I have never had trouble with this scaling before.

Does anybody know what is going on or is having similar problems? Any suggestions? Thanks in advance.

Correct Answer

Matthew,

Thank you for that suggestion. I opened my dwg file in Draftsight, and all my dimensions are correct. So it wasn't the export process that was the problem.

The E-Drawings 2015 measuring tool is incorrect......

Do you have scale 1:1 output enabled in the options of the .dwg save as, plus have the correct reference scale selected (either global sheet scale or individual view scale)?

I'm almost positive that I needed to re-enable that option when I went from 2013-2014, so maybe it's that?

Yes, I have that option enabled. In fact I've tried unchecking it and re-enabling it multiple times... Still comes out as exactly 1:3 scale.

If you have all the main views in sheet scale and choose to enable scale 1:1 and sheet scale for base scale like Matthew showed you it should come out correct. i.e. you might have your views in custom scale that does not match your sheet scale.

I have my only view, and it is in sheet scale. I have the 1:1 scale enabled.

Still coming out as 3:1 scale.

By any chance could it be my e-drawings 2015 not reading the dimension correctly? Or an option within e-drawings itself?

I don't have AutoCAD so I can't test it out within AutoCAD.

Ok I actually am thinking this may an e-drawings issue.

When I import my DWG, that is scaled wrong (according to e-drawings), back into a solidworks drawing, the dimension shows as correct (NOT scaled 3:1 from my original drawing).

Do you have the ability to install Draftsight on your computer? You could use that to test instead of AutoCAD.
