FILLET - How to make a tapered tip

[dburchLYG4N]

Hello Everyone.

I am very new to Fusion 360 and am trying to teach myself by working on a simple project, but am coming across an issue I can't solve myself.

I have a rectangular box made and I figured out how to fillet the edges so that I created rounded corners on one side, but on the opposite side, I want to create more of a tapered edge that goes back about 12mm from the middle tip.

Here is my quick drawing I made to give you an idea of what I want (the bottom part is figured out by using fillet with an amount of 10, but the top tapered part is where I am having issues).

Thanks in advance for any and all help.

Hi, Douglas

  I am also fully understand what the final result you want. I create some snapshots for your reference. If that is what you want. I think you can use sketch constraint to make the model like that. Sketch can make a line tangent to an arc line. Let me know if that is not you want.

Hello chencon,

Thanks for the help.  The 2 pictures you linked are basically what I am going for.

Can you give me a quick run down on how to do this?

I appreciate your help.

You can use a two direction chamfer on the end, then finish with a fillet to get that shape.

+1 for the chamfer approach

@dburchLYG4N - Everyone has their own style but the reason I wanted to chime in is that generally I prefer to keep my sketches as simple as possible. This makes it easier to ensure that my sketches are fully constrained to give me the most predictable behaviour later on as the model gets more complex. Adding the chamfer as a separate feature follows that approach to creating stable geometry 🙂

Hi, Douglas

  I am actually draw an arc first, make the arc center point with distance 12 mm and then create two line to link with them. After that I use tangent constraint applied on them. And Trim useless lines. Add fillet to round the horizontal line and line link with arc if needed.

  Trim, Fillet and Constraint are available in Sketch Mode, 

  I attached a list of screen shot in sequence. Please have a reference.

Thanks

I appreciate the responses!

I will try both ways later tonight (once the little one is asleep) and see which I like best.

I do agree that I want to keep things as "simple" as possible as this is just the first step in learning how to model and I know that things will get much more complex in the future.

Well,  as I literally just started to learn today I guess I am doing OK.

My goal is to be able to build/make functional 3D models that I can then print on a 3D printer by March of 2018 so I guess I have time.

And Conan, thanks for the multiple screen shots... it makes more sense now that I can see how you went about your approach.

Nice! Please post back on the forum with pictures of your prints, it would be great to see how they come out. Just remember that 3d printing can take a few attempts, March will be here before you know it

OK, I didn't have time last night but had a bit this morning and went with the chamfer approach.

I think it turned out well, just had to do 3 chamfer's then fillet the edges and play with the values until things looked good.

Here is what it looks like now.

I will now start playing around with the length so I can make multiple versions (45mm, 50mm, 55mm, and 60mm).. just need to double check the width as well to see if those need modifying too.

Then, I can put them into the same file and convert for 3D printing and see how it goes.

Thanks for the help everyone, I know I will be back with more questions in the near future (I am sure) as I will start on the next learning project in a few days (once I am sure this one is correct).
