Error while importing 3D obj file in Cura

798 6

FabianoRiccardi 3 years ago

Hi, I would try to 3d-print the mechanics of a circuit. So I had exported the 3D model in obj and imported in Cura (v4.8). However it say that the obj file is corrupted. I had tried with different PCBs, but Cura always fails to open them. Does anyone experience the same problem? ![Immagine 2021-02-11 155126.png](//image.easyeda.com/pullimage/CUdt5YNRq7efFPLjefTbZwCogPlFqlFRToBpvyVE.png)

I just tried it in Cura 4.8 and got the same error message.

Importing it into Autodesk Fusion 360 works, but it looks weird. Doesn't have the proper shape. Anyway, from Fusion 360 you can save it as STL for Cura. ![Screen Shot 02-11-21 at 10.22 PM.png](//image.easyeda.com/pullimage/rrHEZOsd9lnrYSElyO9einaCwHmy3XWz7kZh5e0R.png)

@Miraculix200 I can confirm that the file is not imported correctly in Fusion 360. The shape in not the same (some holes are missing) and the scale is wrong (Fusion 360 allows to set differents measure units but not mils, and I suppose that EasyEDA exports only mils)

Even Blender seems to have problems to display obj files from EasyEDA...

@fabiano.riccardi The 3D export scale of EasyEDA is not mil but 1% of the Inch. ( mil x 10 ). This is strange.

> 1% of the Inch. ( mil x 10 ). I assumed it was mils since it is "standard". Hence yet another measurement unit
