Design help for curved pyramid

Hello everyone, could someone tell me how to design a curved square based pyramid with chopped off top,

You description could be many things. An image would help to get an answer.

basically i want to make a pyramid from a squircle, is that possible?

Draw a squircle, whatever that is, make it 3D and scale the top face down.

i tried, it is a sqaure with curved edges, i’m new to sketchup so I might be doing it wrong

Show us what you have tried to do.

Something like this?

Wolfram defines a squircle: Squircle -- from Wolfram MathWorld

ye sort of, think of the base like a squashed circle

It’s like pulling teeth. Do you mean an oval.
Just give us a screen shot. Why make us guess.

If you had posted an image with your question you would have got the answer straight away.

Or asked how to draw an ice cream cone😊
