Are you printing multiple parts? Try selecting all, merge then slice.

commenting to confirm that Selecting all then merging made it work to slice my stuff. I was adding generic cylinder to make a small ad-hoc support on my model

<p>I tried to slice an stl file using the PrusaSlicer console and I got the <code>No layers were detected. You might want to repair your STL file(s) or check their size or thickness and retry.</code> message. I tried repairing the model with 3 different services and I still get the same error.

Then I manually fixed the model using Netfabb and the model is no longer broken according to the gui version.<br />

Yet when I try to slice the repaired model using the console, it fails again.

Yes I know that the files are fine, I don't get why the console slicer is still producing that error.

degenerate faces are faces that do have no surface area... maybe internal geometry?

# Still getting "no layers detected" after repairing model in PrusaSlicer console

(Asked by: username_0 on 2021-04-06)

I tried to slice an stl file using the PrusaSlicer console and I got the `No layers were detected. You might want to repair your STL file(s) or check their size or thickness and retry.` message. I tried repairing the model with 3 different services and I still get the same error. When I load the fixed stl file into the PrusaSlicer gui, it doesn't say that the model is broken. How can the console and gui give 2 different results and how can I fix this?

Here's an image of the model being loaded into the gui version. It states that the model is broken but was automatically fixed.

Then I manually fixed the model using Netfabb and the model is no longer broken according to the gui version.  
[![fixed model](https://i.sstatic.net/I2Cp3.png)](https://i.sstatic.net/I2Cp3.png)  
Yet when I try to slice the repaired model using the console, it fails again.

Still don't have an actual answer as to why repairing the stl file didn't seem to work, but since my stl file was a combination of different stl files I tried repairing the individual stl files before combining them, which resolved the problem.
