Not exactly sure what you mean? You may need to create a series of planes to get the final one you want. Insert an angled plane then a plane offset from the angled plane. And how far is it offset from the existing plane.
The "final" plane is spaced .31" from the first. I have been able to accomplish the desired result but the method seemed rather crude. I had to add geometry in the interim plane which had nothing to do with the desired geometry in the final plane.
Unless you need the offset plane for some other feature I think you could have sketched on Plane <2> and created an Extrude Cut Through All and gotten the same result.
And how far is it offset from the existing plane.
