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 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)
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 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
