normal cut on cylindrical thin wall (NOT sheet metal)

I am trying to make a cut on a cylindrical thin wall such that the cut
surface is normal to the cylindrical surface.

The shape of the cut is from a wrapped elipse on the cylindrical
surface.

I cannot figure out a way to do this. Anyone know how??

 

Off the top of my hide - try this.

Assuming you used the scribe option of the wrap feature.

Use the face inside your wrapped ellipse profile to create a surface
(using offset surface at 0.00). Then insert feature - cut - thicken
with surface and this will create a normal cut.

Otherwise, as you mentioned, make your part as sheet metal and cut
through with normal cut checked, although sometimes this will fail - at
least it will warn you when it does.

 

thanks, that is the ticket.

I found and used a slightly different, (longer) way by offsetting
surfaces on either side of the cyclidrical wall and built a lofted
surface from the edges of those surface and made a surface cut with
that surface. Your way is cleaner and I will change it to that.
