MakeModelEffect Error. The file cannot be saved.

Operating system: window10
Slicer version:4.10.2
Expected behavior: Save the cropped as a STL file.
Actual behavior: Fail in the last step.(Model Maker)

I want to use this program to extract the ears from the CT as a STL file.
But I keep getting errors in the last step.
Here’s what I did.

1.Load Dicom data
2.Select Modules -> Volume Rendering
3.Select Modules ->Crop Volume(Crop only necessary)
4.Select Modules ->Editor
ThresholdEffect(Select right external ear)

But, failed to apply last step continuously.
This is error massage.

Model Maker standard error:

Model scene file doesn’t exist yet: C:/Users/??/AppData/Local/Temp/Slicer/DEGI_AAAAACDCEECDBBHA.mrml
Error: no model hierarchy node at ID “vtkMRMLModelHierarchyNode1”, creating one

What should i do? Please help me.

Hi @11127 -

It looks like your login name is not ascii (and alas Slicer can’t handle that). You should be able to manually change the temp directory in the Edit->Application Settings dialog to someplace with only English characters.

Also, you can update to using the Segment Editor and you’ll have a better set of tools and more STL export options.
