Plane "projection" to sphere

Hi everyone, I’ve got a problem I can’t seem to solve…
How can I “spherify” my plane in order to project it on my sphere afterwards?
Basically I want to cut the sphere with the plane, but if I do this with the Knife Projector…well by getting projected the plane gets really distorted, while I’d like it to keep its proportions…do not realy know if I explained it good enough, probably not :rolleyes:

Shrinkwrap Modifier!

Extrude plane, join both objects and in edit mode select all, Intersect, Self Intersect option. Delete not needed vertices.

I believe shift-numpad7 will give the frontal projection view of a selected face. And then using ortho view mode (numpad 5) will give the correct projection. Knife projection is definetly handy, but I don’t consider it one of those tools that’s as straight-forward to use as it sounds.

So before doing the knife projection, you align your view with the object that you’re using to make cut and switch to ortho.

@pauljs75_ this nearly works, but I should taper the object at the top before before using this method, otherwise the top gets projected too big since I am projecting to a sphere… thanks anyway!
@eppo already tried that way, but as you can see it gets “distorted”…if I do what you suggest I lose all the proportions of the object.
@PyroGXPilot that’s what I was looking for! The problem with this though is that I lose resolution of my object, even applying a SubSurface modifier to the sphere in order to improve the density of the points…is there a way to solve this ?

Thanks to everyone.

According to this i can think of one more way you could project plane onto the sphere (which you could start off in a first place, project and then scale - distort). I’m not quite sure what are the “proportion distortions” you want get rid of though.

also this would be valid at one specific 3D angle
otherwise would look distorted !
