Sharp edge for complex shape

fusionDFG47

I'm trying to make a custom cookie cutter. For that I imported an svg file (had to clean it up a bit first) and then extruded away. The last step would now be to make the outer edges sharp. I tried chamfer, loft and sweeping tool but I can't get it to work. The outlines are somewhat complex but I just can't imagine that this is too much to ask from fusion. There must be a way and I'm just too inexperienced to get this done.

I would greatly apreciate it if someone could help me figure this one out. What is the best way to do this?


I attached the file if that helps.

Hi,

 

I am unable to open your file as my fusion is currently updating however let's have a look.

 

My first impression is that at present what you have is a cookie stamp that will push an

impression into the cookie dough but not actually cut it. If you want the impression of the

inside but to cut out the shape then all you need to do is put a sharp edge on the outside

edge.

 

To do this I would change to the SURFACE tools.

Select the outside edge that you want to cut with and extrude a new surface the thickness

of the dough you want to cut. So 10mm dough you want a 5mm impression and cut the rest.

This means a surface 5mm tall and 10mm deep.

Go back to SOLID Tools and select the Thicken command and thicken up the surface to about 1mm.

Join the two bodies together with the Combine tool

Then use the Chamfer tool to put s small edge on the cutter.

I would use the Two Distance version and only cut half way or it will not

3D print very well.

It would probably be very useful to put tiny Fillets on the inside of the Cutter

so the dough doesn't stick so easily.

If you want to get fancy then you could either put a handle on the other side.

Or you could get really fancy and create a Block for Mass Produced Cookies.

A Quick and Dirty solution but should work.

 

Cheers

This is deceptively tricky to do. The reason for that, as so often, is the quality of the imported svg file. The curves in that file are not tangent. But that isn't the only reason a simple chamfer is failing 😉

The video explains a method to complete that. The model is attached.

Hey everyone

Thank you @Drewpan and @TrippyLighting for your help. I spent a lot of hours trying stuff out before I came asking here and really didn't do a good job of explaining everything. Your assumptions @Drewpan were correct ofcourse and the block for "massproduction" is exactly where I want to go once I'm happy with my prototype. Thank you so much for your detailed description with screenshots and step for step guide. That must have taken quite some time and I really apreciate it a lot. I realize now that it would have made a lot of sense the upload the svg I used too. Sorry about that. Unfortunately your method didn't work either. Maybe it's the tight corners.

@TrippyLighting You're probably correct about the svg being of subpar quality. This was my first time editing an svg file. I went over it again after I read your post and found some more errors and I tried to smooth things out as best as I could after watching some tutorials. It made the process a bit smoother than what you had to go through to make it work. Again, I should have uploaded the svg for you, sorry. Unfortunately your video isn't uploading fully. It's stuck at 157.14MB for me. However thanks to the file you provided I was able to figure thigns out with the timeline. I've never used the surfaces tab before. Always stuck to Solids so I learned a great deal from this. Thank you so much. The only things I changed were having the cutting edge on the inside and I cut a bit off the top in the end as to not have an infinitely small ("sharp") edge but having a width of about .2mm instead.

Thank you both for taking time out of your day to help me out and for being so friendly.

I appreciate your help with all my ... fusionDFG47_0-1769196323592.png

Yes, unfortunately, the company that maintains the forum software seems to forego proper testing before releasing changes, which are also always unannounced.

This has been an issue for many, many years.

For the last few days, when editing posts, they time out, and you'll have to start over. So did this post while I was typing it!

This timed out while uploading the video.

I don't have the video anymore. If you can share your model, I'll create another one.

Mine is a simple cookie cutter and I want it with a V-shaped edge ay the bottom , but i can't figure it out since the figure is complex an I'm a beginner, but would like to earn. I've tried chamfering, extruding with an angle, lofting, surface lofting with no results. Here is my file, many thanks for your help

You need to strongly simplify the curves you sketched, so only larger radii are left.

How much detail do you think a baked cookie can retain?

I would attempt to reduce the number of spline fit points by 30%-50% and ensure that curves remain as large as possible.
