I'm new to using STL's. I've watched several videos but still cannot figure this out. I imported an STL file. It had an issue of "No Volume" and per another post, I did a repair with the 'Wrap' option which took care of that. The STL model is now a beige color. I go back to the Solid Menu, right click on it, and I still do not have the option to BREP it to a solid. My Design History is off so its not that. Not sure what else I'm missing. Here's a picture of what it looks like on my screen.
BREP of STL Not Showing

The option's not in the solid workspace, it's in the mesh workspace. Also no need to turn history off, you never need to even in the past, that hack was just a lack of knowledge!

I had an incomplete BRep conversion (hence the yellow warning), but could fix it afterwards:
File is attached.
Edit: I must note the converted body has problems; I'd rather design it from scratch...

I am not at computer, but remember that side faces of the neck had a curvature so it seems to me it was made by Loft.
But first you should consider the goal of this part. If the usage allows you can make a simpler version (e.g. by Extrude and then cutting side faces with an angle. this will make a flat face)
@hamid.sh. I tried the conversion as well but there are some real odd anomalies in this part that don't add up. Would be nice to see the original solid.
If you look down from the top, the part with the hole through has parallel sides but the neck is tapered with no split between the 2 areas.
And the sides at the bottom also have odd faces that don't make much sense, the face groups in the image above are the beast I could come up with but don't convert well.
Stuff like this where the small fillets are don't make sense, the fillets are parallel but the face is tapered.
I've attached my file so you can inspect the face groupings I came up with. The sides at the base should really be parallel so the clamping screw has flat faces to sit on. This would simplify the model.

@BardutIonut You are not going to have a lot of luck with this I'm afraid! Fillets just kill any chance of an easy conversion and fillets on curved face with more fillets just make it impossible.
This area for example is not going to convert. You might be able to create face groupes manually for all the fillets here but from my experience so far with conversions, for all but the most simple of parts it'll be quicker to model from scratch rather than waste time trying to convert (and failing).

The issue isn't necessarily fillets in general, but fillets that blend into each other.
Thanks Hamid! I found out that my Fusion 360 wasn't updating. It wasn't even showing available updates when I clicked on the clock. So I followed Fusion 360's clean unistall and reinstaller. That got me to the latest version and I was able to open your file. I saved the solid you made vs. trying to re-draw and started to CAM it.
Wondering the best way to do this. I first was just going to do a 2D Adaptive around the contour with the part laying on its side. Then I was going to do a 2nd setup with the part at an angle to cut the slow, thinning the part up the neck portion. I had trouble. I could not get a 2D Contour to go around it though as a finish cut. Not sure why. I backed up and did a 3D Adaptive and thought I'd have the whole thing done. It generated a toolpath but it looked pretty messy. Anyone have any suggestions on the best way to attack this? Below is a pic of the 3D Adaptive toolpath it made. I've attached the file too.
Thanks,
Tom
@SobtzakEngineeringTechnologies I thought you were going to remodel it and not use the converted one as we saw it has problems. Actually I regretted uploading that conversion so I just tried to remodel a simpler version for you. I suggest not going further with the converted model and use the recreated one. I don't know the purpose of this part so I relied on visual clue from the mesh and preferred numbers. Especially side faces are not similar to the mesh but you already mentioned a basic model is enough so I did it with a simple 2D cut of side faces. You should check if the final shape serves the goal of this part:
As for the CAM, I also see that in the converted model even though I can select the contour it won't generate toolpath (one more reason not to use the converted model...). But for the recreated part it works OK:
