Import DXF file in Eagle Pro 6.2.0

I tried using the ULP "dxfimport".  It worked on a .dxf file that I exported from Visio, but it did not work on a file I exported from a mechanical engineering program.  In the latter case, it said there were zero wires, etc; zero of everything.  The file that worked had Imperial units and the one that didn't was metric.  I did remember to select the correct units in the dialog box.  What other reason would explain a file being DOA?  BTW, the file imports into Visio OK.

Hi Rick,

I hope you're doing well. The DXF standard supports many types of

objects, texts, lines, arcs, polylines, etc. The dxfimport.ulp currently

implements the most common objects. However there are still programs

that export designs as SPLINES or other less frequent object types and

the ULP currently can't handle them. Also Binary DXFs exist versus the

text based ones the ULP is setup to handle so you have to make sure

you're using a text based DXF file.

If you're program can export various types of DXF files try the

different forms out and see what you get.

Both the successful and unsuccessful .dxf files use splines.  They are not binary files.  The only unique type in the unsuccessful one is "CEPSN TYPE".  However, shouldn't the ULP at least import the types it knows about, or produce some sort of error message?  It just happily reports zero lines, zero circles, etc.  The .dxf files are being produced by my mechanical engineer with his CAD program, so I am not in a position to waste his time with endless experimentation with .dxf files.  He already tried several different CAD programs that output .dxf.   I guess there is no documentation as to what is or is not supported.

Hi Richard,

There's more to it than that. The SPLINES are never imported because the

ULP doesn't support that yet. As of now the ULP supports the following:

LINES,

ARCS

CIRCLES,

POLYLINES,

and

LWPOLYLINES

That's it, the file that imports properly has one or more of these

elements. The one that doesn't lacks these completely.
