This how-to is for correcting axis orientations or rotation issues when exporting a file from Inventor to Cura.
improper orientation causes this issue in Cura
Export as an STL and import into Cura (how to export a STL here)
Do not rotate the model in Cura
Rotate your view in Inventor to match the Cura model. This will make the next steps more intuitive.
In the “Move Bodies” dialog box, select the last item from the drop-down – “Rotate about line”
Select the line you’d like to rotate around.
This should be the same rotation you’d like the part in Cura to rotate.
Click “Bodies”, then click your part.
You can change the angle, if needed.
Press OK to rotate the model.
Export a new STL and import into Cura
The model should now be properly oriented in Cura!
