Hi Brian, yeah I think you understood it better than me re: cutting edge.

If you want something like thin metal, you can select the bottom face and use Construct > Offset > Shell:





or maybe like this, here with another offset to make a middle piece, move that in Z and then Construct > Loft between the 3 profiles using Loft style = Straight.

Hi Michael,

Cool techniques your are showing!

I particularly like your Shell design. It seems more "historical memory" correct, IMHO.

If these are for a Twitter party, perhaps one half should be broader...

Many thanks! I am light-years away from knowing what I do, that's a painful insight. ;(

Btw, nothing to do with Twitter or X, just an extreme form with many sharp angles,

Ok, to work now. My wife is preparing Christmas, not.

Thanks again !

Hi,

Sweep (two rails) is a good and easy way for me.
Profile is the red polyline and rails are the magenta polylines.

You can chose the profile too...
Because the printability could have be done by a minimum of material.



If the shape of your cookie cutter is less simple, you can rebuild the shape to have something softer.
Cookies don't need a millimetric precision.

You could cheat a little.
Select just a face and extrude-tapered. A "Perfect point" will fail and disappear, but you can zoom in and stop just before it is a perfect point.

In real life there is no such thing as a perfect point.

Then you can separate all the pieces and show points and just grab and stretch the bottom points down for as tall of an extrusion as you need.

Here's another way to do it as well.

Maybe advantageous to have a straight cutting edge inside the cookie cutter ?

I like this one vic

And then the machine mechanism would have a little “pimp walk” on the way up… seperation!
