Issues with DXF's

[matthewZYUPT]

I'm constantly having issues with getting DXF's. I always have to do something weird to get them to work. So far the best method I've seen that works is. 

Working method:
Open part.

select fact.

export face to DXF.

This method works however there are some issue..
If there are 3D fillets that are not grabbed and cut at there line resulting in inaccurate silhouettes
I can only select one surface to export 

Sometimes I can manage to export the part as a dwg open in autocad then copy and paste it into a file that worked and resave it as a different part number but I'm still working on figuring out what file formats work for it. So far it looks like the dxf type of " autocad R12/LT2 DXF" sometimes works but not all the time. I've even tried just a plan "export to cad format" to dxf, open in a drawing and save as a dxf, save as a dwg and open in autocad and save as a dxf

Maybe its just the machines we are using at my company that are picky but it would be nice to just have a Ilogic rule that I can just hit run and it will export a 1 : 1 scale dxf but deciding on what face might be the hold up so preferably something I can hit run and it will export the top , front and side views as 1 : 1 dxf's would be nice as it would be "right click left click"

If you have the templates and units set up correctly then the dxf must come out 1:1.
Check program, document and export settings.

I use "export surface as (RMB)" when the flat pattern is enabled, though for bulk I use Drawing Porter for example.
I usually use DXF 2007 or 2010. This has never been a problem and I work with plants within 500 km radius.

Which does not change the fact that I always attach a pdf drawing with the overall dimensions of the cutting and all bending dimensions. This is an important good practice to avoid mistakes, just in case.

If the pattern is not flat, for example you have sloping walls, then a step format would be a better choice.

What is the end result you are looking for?

2D dxf or 3D dxf?

If it's 2D, typically you would create a drawing first, either idw or dwg.  Then export that out to dxf.

The scale isn't the issue. The type of format isn't being accepted by the machine or it isn't grabbing the wrong face. I might want to try step files next but the type of machines we use here are pretty old and might not like that as a format (like late 2001 to early 1980-1990).

Check the layer line types in the export template. And then check in AutoCAD that the contour is a closed loop.

[matthewZYUPT]

2D dxf to be used to machine that flat plane. The export is either not working or the file formats provided don't work for the machines.

Can you send a sample plate?

Hi Matthew,

Maybe there are iLogic related solutions. You might want to google it ("Autodesk Inventor iLogic DXF Face").

Here are two related apps on the App store.
