360 revolve has irregular surfaces

[Anonymous]

Hello there! 

Creating what I thought was a simple bowl from a profile sketch - sketch from center axis, profile of half the bowl - but when I do a 360 degree revolve there are some irregularities in the surface of the body it creates. Even when I do a 180 degree revolve, mirror, and combine, there are still some irregularities. My sketch has several splines, but it is relatively simple and shouldn't be causing issues from what I can see. Any ideas? Thanks!

What is your realistic manufacturing tolerance?

In these two examples - the max difference between my revolve and your revolve is about the thickness of a sheet of paper.

Hello!

Thank you for this - can you tell me what you did to create this from my sketch? Do you have any ideas why mine was creating this irregularity? Just trying to figure out how to prevent this in the future.

Thank you again,

Ali

I think it's just a display meshing artifact. If you right click the body in the browser and select Display Detail Control from the menu then select Fixed and set Display Detail Level to High the artifacts go away.
