Extruding a thingiverse .stl file in Audodesk Fusion 360 is not working

Question

I am trying to extrude this end of my thingiverse file in fusion 360. It is not letting me extrude it when I am in the model view.

Is this typical of thingiverse files? (not being able to extrude/modify?) Or am I missing some steps?

Thanks,

Joe

I found this https://forums.autodesk.com/t5/fusion-360-design-validate/import-and-edit-stl-file/td-p/7899170.

It states the following which I tried and was able to extrude the stl.

"Another option is to convert the STL to a brep object. Do this by changing to Direct Modeling mode by right clicking on the top node in the Browser, then selecting 'Do not capture design history'. Right click on the mesh body and select 'Mesh to Brep'. You can now edit the Brep model."
