FUSION 360 FORUM ARCHIVE

The f3d archive also contains the sketches in what appears to be the same format, so hopefully that would work as well.

As the InventorLoader project clearly contains code to parse the SAT file, perhaps it won't be a huge deal to modify it to parse this slightly different format in the f3d archive.

All the ASCII text looks pretty much the same, just the numbers are encoded in a different way it seems. However, the format of the SAT file looks extremely similar to one of the formats inside the f3d archive. I did also try exporting a SAT file from Fusion and importing it into FreeCAD using InventorLoader, which didn't bring over the sketches either. This export option will probably also go away with the new Fusion licensing stuff. Additionally, Fusion says the IPT conversion must be done on the cloud which means it took 5 minutes to convert a file with a single cube. I tried with one of the example IPT files from the github repo and it did work correctly, so it seems like Fusion IPT export is basically the same thing as exporting to STEP (or its IPT format is slightly different). Unfortunately, the sketches and design history didn't come through. I was able to export an IPT file from Fusion and import it into FreeCAD. I don't know the state of it, but it's probably a good starting point.

There was an effort to write a parser for inventor files (.ipt?), these can be exported from fusion360. Do you think it's achievable? Are there any major problems you foresee? Would you be interested in working on it? etc. I was just curious on hearing what other people think about this idea.

I've also never done any significant software reverse engineering or dealt with non-tesselated geometry file formats. I'm very new to FreeCAD (only been messing around for a few hours), so I'm not particularly familiar with how everything works. I also put Fusion into Ghidra to have a look around at the decompilation and there looks to be some interesting stuff going on in libASMkern226A.dylib (Mac version).Д®ven if Autodesk ends up significantly changing the format in the future, I think it would still be worthwhile to pursue this to allow people to transition to FreeCAD more easily and to possibly maintain the ability to export useful formats from Fusion. There's stuff like 'face' 'loop' 'edge' in there along with a bunch of repeated bytes and some bytes that are probably a set of coordnates encoded in some way. There is some ASCII text that can hopefully help with reverse engineering the format. The files inside the archive do not appear to be entirely binary.

Perhaps, for example, an F360 sketch could be broken up into multiple smaller ones for each extrude/pad, allowing some parametricness to be retained. I know many of the features of Fusion 360 are not supported in FreeCAD and that there are some fundamentally different ways things are modeled, but it seems like there would be some additional information to be gained when compared to just importing a STEP file. There's a directory with what appears to be some kind of BREP representation of each of the project's objects and some other files that seem to encode the design history.

Ideally, this would allow preservation of at least some of the sketch and operation history.ДЄn f3d file is a compressed zip file with a number of binary-ish files inside. As many people are coming over from Fusion 360, including me, I was wondering if it would be possible to create a converter to allow importing of Fusion 360 archive files (f3d) to FreeCAD.
