Export Logo & Text in Inventor to a DXF-file with polylines (NOT segmented lines)

amanda.pehrson — Thu, 05 Sep 2024 12:08:24 GMT

I received a logo and text from a customer that will be milled with CNC into the steel for their product. I got this as a STEP. I want to export logo and text as a dxf file with polylines for the CNC workshop.

I have tried projecting their logo and text in a sketch and exporting the sketch as dxf. The result => segmented lines
I have tried making the letters into a inverted surface and exporting as a surface. The result => segmented lines

I search this community and there are similar problems and also claimed solutions (which doesn't solve the issue).

Help me! For the moment I need to join all the different lines/curves in Illustrator. Letter by letter...

If the logo is a .stp file, you can just set it inside another piece of Go and do a boolean, which will give you a new face with that "logo shape." Then you'll have a profile, or you can export that face as a dxf.

That is what I have done in one of the examples. When exporting the dxf-file I still get segmented curves (many seperate curves/lines for each letter) , not a continuous curve for each letter (polyline). So it is still a problem.

Hello,

Illustrator should work with DWGs too. There might be a better curve description and a better outcome to be had that way. I know this works in some cases and- if you still have a copy of Illustrator CS2- it might just work perfectly. The more modern Illustrator´s DWG readers have changed a bit when it comes to curve description.

I hope this helps.

I tried exporting as DWG instead and I still have the same problem, both when exporting from sketch and exporting from face. The letters and logo are still segmented curves/lines.

Hey,

sorry that didn´t work. Can you share a sample dataset? I can have a look, even though I have tried a similar workflow with Illustrator CS2 and the most actual version already and got nothing other than segmented output files either. They can be seamlessly joined though.

You can try and export a really high resolution TIFF from Inventor and vectorize this in Illustrator or convert the selection to a path in Photoshop. All you have to do is a DPI to pixels output calculation for Inventor and aim for 900 to 1200 dpi TIFF files at a 1:1 scale for Illustrator. The outcome should be useable.

Kind regards

Daniel

Thanks for the suggestions! I ended up joining all segmented lines in Illustrator but had to do it one letter loop at a time. It is too time consuming, should be possible to get each part of the letter as one loop just exporting it from Inventor.

Attached you find a "test file" with an example with what I try to export from Inventor as polylines in dxf/dwg.
