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:

- Fillet

- Change radius type to Variable

- Select the lines, add points where desired

- Enter values or drag the handles

I will upload my screencast once it is approved

Hi. This doesn't really get the forms I'm looking to achieve. This is just a uniform fillet.

You want me to accept the solution before I see the result? I have tried these steps and can't get it to look correct. Curious to see your result 🙂

@Anonymous Why can't I show my screencast?!

Copy the link below to see the screencast I did earlier.

It does look like the part has a small uniform radius with a chamfer. For that one there are many ways. If below does not make sense please notify and I will screencast.

Here is the easiest;

Create a plane on the desired angle (where you want it to start, end, depth, etc) then use that plane to split the body and delete the extra. Then uniformly radius the edges.

I don't mean to interupt but I'm new and haven't seen a screencast before. That was amazing.

Hi Ryan. Thanks for sharing that technique and the shared link worked good for me to see the screencast. 🙂

I'm not entirely convinced though by the method as it produced a similar but not the same forms. Perhaps there is no way to exactly reproduce the shapes seen in fusion. I'm using this project as a way to learn fusion so taking the time to learn some more advances techniques for creating these shapes would pay dividends in the long run. Apologies if it seems like I'm being too particular or obtuse 🙂

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!

Hi, apologies for this piece offending you so much. As mentioned I'm using this project to learn fusion 360 so any advice would help more than just telling me I'm being sloppy. It's not very constructive to improving the way I work.

I attempted to resolve the issue you highlighted and was unable to. How can I remove this artefact? This is one piece out of many for a gun I'm producing so I need it to stay the same size and shape.

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.

That's some great advice and you hit the nail on the head with the game props comment 😁 That's exactly what I'm doing. That said I try model things in a way that makes sense as it results in a more grounded and believable game assest in the end. I'll go through the tutorials in your link though, thank you.
