Cut with two or more surfaces. Possible? e.g. A pyramid from a cube

Is it possible to cut with two or more surfaces at the same time? E.g.
If you have a cube you could cut a pyramid shaped hole in it. Three
surfaces could be defined to intersect at a point within the cube.
Then if you could cut to the three surfaces, the pyramid would be
removed. Is there an easy way to do something like this? Thanks

 

I think you would need to knit the surfaces into a coherent body before you
could cut with them all in one go.

 

The knitting Lee refers to would also require that the surfaces be
trimmed beforehand (if any of their edges overlap).

You may want to consider an alternate approach of cutting the "pyramid
shaped hole" by inserting a Lofted Feature which cuts between a sketch
(for the base of the pyramid and a second sketch which represents the
tip with only a single point. (Strangely enough, a point can be used as
a profile at the beginning or end of a series of loft sections.)

How about sketching a triangle on a plane or surface and cut-extrude with
enough draft to get a point.

The easiers thing you can do is do a mutual trim with the surfaces, I
dont see why you would want to knit them together before you have even
trimmed them up

insert, surface, trim....

 

Have you tried this? If you make the pyramid by lofting from a point to
a triangle, the three surfaces are all knit together into a single body,
and yes, you can cut with it as long as the faces are knit into a single
body.

Of course you could do a lofted solid cut as well.
