Polygon representation of circles when exporting as DXF/DWG

Hi everyone :-)

I am running Solidworks SP3 2013 and trying to export a 2D design as a DXF which has been sketched in the 3D representation area. The only problem is that some of the splines and the outer circle is not expressed as a continuous curve and instead as a very rough polyline when exporting as a DXF. Of course I have messed around in the DXF "options" changing all the logical parameters like "high Q DWG export", "Export splines as splines" and using the latest version R2010 and older versions like R14. The issue is still there.

I read that perhaps changing the image quality in "document properties" might help, but still no luck.

Come on Solidworks, I have bigged you up to my peers, don't let me down! Pro-Engineer does not have the same issue!!

Best Regards

Nick

What are your Image Quality settings under Document Properties? Crank them up higher.

Hi there :-)

The settings are as follows:

Shaded and draft quality HLR: 0.1515mm

Wireframe and High quality HLR: High(slower)

Improve curve quality at higher settings.

What is wierd is I do have some designs which do not show this polygon related issue, even if they are pretty similar in size??!

Best Regards

Did you ever get a resolution to this? Upgrading the display settings seems to have no effect.

Others recommend extruding the curves and then selecting the edges. In my case, I don't have closed curves, just lines I want traced so this is not an option.

Agree with Nick, this should not be a challenge, yet somehow it is.

Answering my own question, I've found a potential workaround that I haven't seen mentioned elsewhere.

I noticed that when I export a part file as a dxf, solidworks creates a drawing in the background to accomplish the task.

I realized that this might help me accomplish what I was trying to. So rather than use the part file, I created a drawing using the part file with only the line art I wanted to export visible. Then, exporting the drawing file to a dxf creates a file of acceptable resolution with properly curving splines.

In my searching I've found several forum topics that address this basic question, and i believe this would answer them all.

One additional note, I added a point in the drawing at the origin, this way when the line art is imported with the part file for machining it will be easier to line up.

Maybe the problem isnt in your dxf file. If you are using Autocad or Draftsight to open your DXF files, try :

Viewres enter

do you want fast zoom (yes or no doesnt matter)

20000 enter

It used to be well documented in Autocad
