Hey. I'm presented with a unique challenge in my project where an edge needs rounding off in varying amounts. I would really appreciate any help with how a form like this is produced. (The weapon in question is the Korth NXR Revolver if you're curious.)
Here's a reference image of the part:
And this is how I'd expect it to look.
Here is my basic shape without the fillet.
And the cad file:
The thing it that this isn't just a fillet.
In general, your modeling workflow is incredibly sloppy and imprecise, and creates artifacts that can cause a number for problems later. More precision is needed!
I am not offended by your modeling technique. Frankly, most of the folks that I've seen modeling weapons do this to create game props. For that, accuracy is only needed not to hinder further modeling. It is also irrelevant if parts line up perfectly as the model is only used for visuals.
If you really want to manufacture this thing, I would strongly recommend going through one of the tutorial courses here. 3D modeling and Assemblies is what you need first. I've not watched these for obvious reasons, bit I hope the 3D modeling course includes a solid introduction to proper sketching techniques.
That is what your first focus should be.: Develop sound sketching techniques and habits. Simple, fully defined (dimensioned and constrained) sketches build the very foundation for good CAD models.
Once you have gone through some courses and tutorials you will still have questions, perhaps even more than before, but you will be much better equipped to ask these questions and this is where we can really help guide you.
