Hello. I can not find how I can bulge a cone in my project. I need to put these cones on top of each other after 3d printing.

Could you advice me please.

Many thx. Ondrej

Not sure what you mean by ‘bulge’. Where do you want the bulge to be?  
If you want to stack them, like the traffic cone you made (right cone w/square base), simply shell out the bottom and then they can stack.

Yes, I must have translated it wrong. I was thinking of a traffic cone and I need to put them on, but I don’t know how to make the hole down there to copy the outer shape. Can someone please edit it or show me the function? Thank you, Ondra

Use the **Shell** tool to hollow out the cone.
