Cura 4.13.1 - Can not ungroup stl objects saved from Solidworks

[CrushGrind_Sam 1]

Hi all, 

 

I used to import directly from solidworks but this no longer works. It always says that the file is corrupt or doesn't exist. 

So I thought I would just save as stl file and but I cannot ungroup the objects in Cura. 

 

Any help or ideas will be greatly appreciated! 

 

Thanks,

 

Sam

Saving as a 3mf is always superior. As for the rest, download the meshtools plugin.

An STL file does not support multiple "bodies". In the STL file, your objects become one combined mesh, even if not all parts of that mesh are connected. They are not so much grouped, they are one mesh. That is why you cannot ungroup.

 

The Mesh Tools plugin, available from the Marketplace, adds a function to split such meshes that consist of multiple "non-connected parts".
