Elliptical cutting path of Cylinder at an angle

I am trying to obtain the elliptical shape or cutter path that is formed when slicing through a cylinder at an angle. I would like to be able to select the angle and do a cross-sectional cut and then have a way to copy/extract the shape of the ellipse on the cut surface to be able to cut it on a CNC cutting machine. This will allow us to accurate cut the hole for a cylinder to be welded into at an angle.

 

Thank in advance.

Draw cylinder.

Draw plane (oblique to cylinder) where you will make the cut with NC

Copy plane parallel so that it intersects the cylindere

Go to Surfacing tab and choose Intersect command (and intersect cyl and copied plane)

Then either:

1. Draw a sketch on the original plane and choose the "Include Edge" command to copy the intersection onto the plane.

2. On the surfacing tab, choose the project to surface command and project the intersection curve onto the target plane.

After the angled plane is made, when the cylinder is created as a solid using the Extrude command, the Intersect command is disabled. When the cylinder is created as an 'Extruded Surface', Intersect is available.

May be this is a no-brainer for many but I spent some time figuring this out, hence thought of sharing.

Hi Tushar,

Yes, Intersect command is disabled, because You have only one surface. You need more than one. I think Dan was thinkig of Intersection Curve (Surface tab -> Curves group).

Hi Imi, you are absolutely correct. When I first tried the solution given by Dan and was stuck with the Intersect command, Intersection did not occur to me. My bad Smiley Embarassed

I must not be getting something because this seems backwards. Why don't you make a plate in solid edge and then cut it with a cylinder? If you do in sheet metal it will automatically compensate for the thickness, too. Then you can take the part directly to the CNC software.
