Cookie cutter with edge

[mnsh.varshney]

Hi,

Learned a lot in last few months, but today stuck on something that could be really easy, but I am having trouble. I will try my best to explain.

So what I need is a cookie cutter with the shape of a ship anchor (image attached). So, I have been able to make the design but getting stuck when it comes to making a nice edge on the cutter so that it can cut, I have been able to do this previously using chamfer with radius and angle (stl attached of that), but this time due to the too many curves its failing or giving some weird result. 

I want to obviously get help on how to complete it but little understand if there is another way this can be achieved as well. 

Huge thanks in advance for any help I can get.

Maybe you could use a sweep along a path to cut out the angle you want.  I would just create a thinner shell rather than trying to make it thinner as it goes down.

I tried to sweep but it is failing too, maybe for the same reason as for chamfer. I will eventually have to make thinner shells, but its just nagging me and I want to get it done.

can you post the file?

Hi,

I tried the chamfer and it worked well

Here is a shot of my try ( file is attached )

Hi thanks for the try, but chamfer is after getting a kind of shell and that too on the outer edge. Then you will see the problem, highlighted one of the edges that give trouble. Thanks.

Hi, I am sorry how do I do that, so naive I am. Would a step file work?

Just to update, I gave up on trying to make an angled edge and then just used thin walls for the part I wanted to serve as cutting edge. But still, would love to know if that could be achieved and how.

From the File menu click on Export, then choose Archive (*.f3d) and attach the output to your post.

Attached the file. 

Thanks.

Here's the cutting edge. Tip: next time only sketch half of the shape and complete half of he solid model.\, then mirror the solid. that sees a lot of work in this model!

1. I created an offset line between the two small profiles to define the cutting edge.

2. I created a 1mm offset plane on top of that flat section where that curling etc would sir on.

3. I projected that new offset line into that sketch.

4. I went into the patch workspace and created an offset surface of that top surface.

5. I create many simple surface lofts between the edges of the offset surface and the projected sketch lines.

6. I stitched it all together to get a solid.

7. I combined it with the rest of the cookie cutter.

Sorry to respond to such an old thread but I was wondering if you can show me a quick video on how you did this? I'm very new and I'm also trying to make a cutter that has a sharp edge.

This is an old screencast so Fusion 360's UI might not be exactly the same anymore. But the genreal approach is still the same.
