Ok, picture a broom handle and then slicing an end off at a 45degree angle.

I was trying to use a boolean with a cylinder and a plane rotated at 45.

The option of A intersect B with the Cylinder as A and the plane as B is the exact opposite of what I'm trying to do.

Is there an easy way to do this besides the more meticulous of editing points? Keeping a radius while editing points is proving to be quite a task

Well, after a nights rest, I saw that I could use a circle spline, rotate it -45, extrude, make it an object then use the knife in plane mode to cut off a straight end leaving the other end angled.

I'd still appreciate any other ways to do the same thing but I figured out a way.

Thanks!

For future reference, here are a couple other ways you could go about it:

1. Create two identical circle splines. Use the Mesh>Spline>Project command to project one of them against a plane or cube rotated to 45 degrees. Use a loftNurbs to loft the two splines together;

2. Create a cylinder and make it editable. Use the knife tool in line mode to cut a 45 degree edge loop into the cylinder (holding down shift restricts to 0 and 45 degrees). Delete the unwanted polygons and then use the "close polygon hole" command to create a new cap.

Thanks Adam, that kind of thinking is what helps me learn!
