Crash when trying to export sketch as DXF

FreezeS — Fri, 15 Apr 2016 17:14:52 GMT

Hi guys,

I imported a DXF from Autocad, modified it a bit and now I'm trying to export it.

I select the sketch, right click on it and Export to DXF, then it crashes.

The document is the following: http://a360.co/1VuTzE7

I tried to use an extension but that still fails.

I open the sketch and then try to use Export to DXF (Splines as polylines) I just get an empty window with the text "Number of sections to split splines into" and if I click Ok it exports an empty file.

Please let me know if you can fix it or find a workaround.

Cheers,

Bruno

Tried it on my iMac and the "save as DXF" worked fine here.

Of course it it's used for laser cuting it still need some cleanup as that exported DXF incudes all the construction lines that are likely not to be cut with a laser.

Sorry, forgot to mention. Win7 64bit, fusion version 2.0.1980.

PS: Can you send me that file? I can clean it up and I need it. 🙂

Sure. PLese find it attached.

In general I am noticing that the imported file has a lot of sketch elements that shoud reperesent closed profiles but for some reason are not.

I've found the in Fusion 360 the easiest and fail save method to create outlines for laser cuting is to extrude somesolid geometry, then create a sketch on top od that geometry with projected sketch elements.

That's the problem, some lines were linked, some not.

However, with the file you send me (as with the one I managed to export using the extension), the model is empty, the drawing is actually in the layout.

When I exported it to dwg it changed the dimensions slightly. Where I had 20 now I have 0.2102.

Should I scale it until I have the right dimension or is there a better way to do it?

I opened the DXF file I exported from Fusion 360 in Geomagic Design and it shows exactly the dimensions I see in Fusion 360, so at the moment I am not sure what I can change.

However, moving forward I'd love to show you how to design this in Fusion 360, possibly much more efficiently than it's done currently.
