How to make a pyramid?

[PEU]

Im trying to model a pyramid like the egiptian pyramids, Im probably missing something, but I tried angled planes 3dsketches and other aproaches and I can't get what I want.

Any help would be greatly appreciated. Thanks

Sketch a square, extrude with a Draft.

1) Create sketch of whatever base pyramid shape you need and close the sketch.
2) Create a 3D sketch and place a point at the required apex position and close the sketch.
3) Use the Loft tool and select the two sketches.

Similar to CBL's suggestion, without the 3D sketch.

Thanks a lot Guys! I found corblymey way easier, mostly because Im more familiar with the loft command!

Cheers!

Jeff, I'll have to wait for a few more weeks before I can open your file. Can you save it as a SW07 file?

I can't open your SW08 model.

The Great Pyramid is 755.5ft at the base and 485ft tall. Does SW08 still have that 1024m limitation?

Here's a screen capture of the pyramid, showing dimensions.
I wasn't thinking about the '08 thing, it was simply open at the time, so I used it.

PEU - I still created a loft, but didn't use a 3D sketch. I simply offset a plane the distance needed (

Ugh...wrong button...

PEU - I still created a loft, but didn't use a 3D sketch. I simply offset a plane (from the top plane) the distance needed (5820 inches) and put a sketch point on the origin, while using a centered square on the top plane.

Ahhh, I see. I was being uber lazy and didn't want to waste all that effort creating another plane.

How about even lazier yet, create the base on the top plane, create a point on either the front or right plane at the height required and then loft between the 2. Only requires 2 regular sketches and a loft.

Yeah, but then you have to select a plane ... and that involves another click.
